* Starter PKI CA Storage API (#14796)
* Simple starting PKI storage api for CA rotation
* Add key and issuer storage apis
* Add listKeys and listIssuers storage implementations
* Add simple keys and issuers configuration storage api methods
* Handle resolving key, issuer references
The API context will usually have a user-specified reference to the key.
This is either the literal string "default" to select the default key,
an identifier of the key, or a slug name for the key. Here, we wish to
resolve this reference to an actual identifier that can be understood by
storage.
Also adds the missing Name field to keys.

* Add method to fetch an issuer's cert bundle
This adds a method to construct a certutil.CertBundle from the specified
issuer identifier, optionally loading its corresponding key for signing.
Signed-off-by: Alexander Scheel <alex.scheel@hashicorp.com>
* Refactor certutil PrivateKey PEM handling
This refactors the parsing of PrivateKeys from PEM blobs into shared
methods (ParsePEMKey, ParseDERKey) that can be reused by the existing
Bundle parsing logic (ParsePEMBundle) or independently in the new
issuers/key-based PKI storage code.
Signed-off-by: Alexander Scheel <alex.scheel@hashicorp.com>
* Add importKey, importCert to PKI storage
importKey is generally preferable to the low-level writeKey for adding
new entries. This takes only the contents of the private key (as a
string -- so a PEM bundle or a managed key handle) and checks if it
already exists in the storage.
If it does, it returns the existing key instance.
Otherwise, we create a new one. In the process, we detect any issuers
using this key and link them back to the new key entry.
The same holds for importCert over importKey, with the note that keys
are not modified when importing certificates.
Signed-off-by: Alexander Scheel <alex.scheel@hashicorp.com>
* Add tests for importing issuers, keys
This adds tests for importing keys and issuers into the new storage
layout, ensuring that identifiers are correctly inferred and linked.
Note that directly writing entries to storage (writeKey/writeissuer)
will take KeyID links from the parent entry and should not be used for
import; only existing entries should be updated with this info.

* Implement PKI storage migration.
- Hook into the backend::initialize function, calling the migration on a primary only.
- Migrate an existing certificate bundle to the new issuers and key layout
* Make fetchCAInfo aware of new storage layout
This allows fetchCAInfo to fetch a specified issuer, via a reference
parameter provided by the user. We pass that into the storage layer and
have it return a cert bundle for us. Finally, we need to validate that
it truly has the key desired.

* Begin /issuers API endpoints
This implements the fetch operations around issuers in the PKI Secrets
Engine. We implement the following operations:
- LIST /issuers - returns a list of known issuers' IDs and names.
- GET /issuer/:ref - returns a JSON blob with information about this
issuer.
- POST /issuer/:ref - allows configuring information about issuers,
presently just its name.
- DELETE /issuer/:ref - allows deleting the specified issuer.
- GET /issuer/:ref/{der,pem} - returns a raw API response with just
the DER (or PEM) of the issuer's certificate.

* Add import to PKI Issuers API
This adds the two core import code paths to the API:
/issuers/import/cert and /issuers/import/bundle. The former differs from
the latter in that the latter allows the import of keys. This allows
operators to restrict importing of keys to privileged roles, while
allowing more operators permission to import additional certificates
(not used for signing, but instead for path/chain building).

* Add /issuer/:ref/sign-intermediate endpoint
This endpoint allows existing issuers to be used to sign intermediate
CA certificates. In the process, we've updated the existing
/root/sign-intermediate endpoint to be equivalent to a call to
/issuer/default/sign-intermediate.
Signed-off-by: Alexander Scheel <alex.scheel@hashicorp.com>
* Add /issuer/:ref/sign-self-issued endpoint
This endpoint allows existing issuers to be used to sign self-signed
certificates. In the process, we've updated the existing
/root/sign-self-issued endpoint to be equivalent to a call to
/issuer/default/sign-self-issued.
Signed-off-by: Alexander Scheel <alex.scheel@hashicorp.com>
* Add /issuer/:ref/sign-verbatim endpoint
This endpoint allows existing issuers to be used to directly sign CSRs.
In the process, we've updated the existing /sign-verbatim endpoint to be
equivalent to a call to /issuer/:ref/sign-verbatim.

* Allow configuration of default issuers
Using the new updateDefaultIssuerId(...) from the storage migration PR
allows for easy implementation of configuring the default issuer. We
restrict callers from setting blank defaults and setting default to
default.
Signed-off-by: Alexander Scheel <alex.scheel@hashicorp.com>
* Fix fetching default issuers
After setting a default issuer, one should be able to use the old /ca,
/ca_chain, and /cert/{ca,ca_chain} endpoints to fetch the default issuer
(and its chain). Update the fetchCertBySerial helper to no longer
support fetching the ca and prefer fetchCAInfo for that instead (as
we've already updated that to support fetching the new issuer location).
Signed-off-by: Alexander Scheel <alex.scheel@hashicorp.com>
* Add /issuer/:ref/{sign,issue}/:role
This updates the /sign and /issue endpoints, allowing them to take the
default issuer (if none is provided by a role) and adding
issuer-specific versions of them.
Note that at this point in time, the behavior isn't yet ideal (as
/sign/:role allows adding the ref=... parameter to override the default
issuer); a later change adding role-based issuer specification will fix
this incorrect behavior.

* Add support root issuer generation
* Add support for issuer generate intermediate end-point
* Update issuer and key arguments to consistent values
- Update all new API endpoints to use the new agreed upon argument names.
- issuer_ref & key_ref to refer to existing
- issuer_name & key_name for new definitions
- Update returned values to always user issuer_id and key_id
* Add utility methods to fetch common ref and name arguments
- Add utility methods to fetch the issuer_name, issuer_ref, key_name and key_ref arguments from data fields.
- Centralize the logic to clean up these inputs and apply various validations to all of them.
* Rename common PKI backend handlers
- Use the buildPath convention for the function name instead of common...
* Move setting PKI defaults from writeCaBundle to proper import{keys,issuer} methods
- PR feedback, move setting up the default configuration references within
the import methods instead of within the writeCaBundle method. This should
now cover all use cases of us setting up the defaults properly.
* Introduce constants for issuer_ref, rename isKeyDefaultSet...
* Fix legacy PKI sign-verbatim api path
- Addresses some test failures due to an incorrect refactoring of a legacy api
path /sign-verbatim within PKI
* Use import code to handle intermediate, config/ca
The existing bundle import code will satisfy the intermediate import;
use it instead of the old ca_bundle import logic. Additionally, update
/config/ca to use the new import code as well.
While testing, a panic was discovered:
> reflect.Value.SetMapIndex: value of type string is not assignable to type pki.keyId
This was caused by returning a map with type issuerId->keyId; instead
switch to returning string->string maps so the audit log can properly
HMAC them.

* Clarify error message on missing defaults
When the default issuer and key are missing (and haven't yet been
specified), we should clarify that error message.

* Update test semantics for new changes
This makes two minor changes to the existing test suite:
1. Importing partial bundles should now succeed, where they'd
previously error.
2. fetchCertBySerial no longer handles CA certificates.

* Add support for deleting all keys, issuers
The old DELETE /root code must now delete all keys and issuers for
backwards compatibility. We strongly suggest calling individual delete
methods (DELETE /key/:key_ref or DELETE /issuer/:issuer_ref) instead,
for finer control.
In the process, we detect whether the deleted key/issuers was set as the
default. This will allow us to warn (from the single key/deletion issuer
code) whether or not the default was deleted (while allowing the
operation to succeed).
Signed-off-by: Alexander Scheel <alex.scheel@hashicorp.com>
* Introduce defaultRef constant within PKI
- Replace hardcoded "default" references with a constant to easily identify various usages.
- Use the addIssuerRefField function instead of redefining the field in various locations.
* Rework PKI test TestBackend_Root_Idempotency
- Validate that generate/root calls are no longer idempotent, but the bundle importing
does not generate new keys/issuers
- As before make sure that the delete root api resets everything
- Address a bug within the storage that we bombed when we had multiple different
key types within storage.
* Assign Name=current to migrated key and issuer
- Detail I missed from the RFC was to assign the Name field as "current" for migrated key and issuer.
* Build CRL upon PKI intermediary set-signed api called
- Add a call to buildCRL if we created an issuer within pathImportIssuers
- Augment existing FullCAChain to verify we have a proper CRL post set-signed api call
- Remove a code block writing out "ca" storage entry that is no longer used.
* Identify which certificate or key failed
When importing complex chains, we should identify in which certificate
or key the failure occurred.
Signed-off-by: Alexander Scheel <alex.scheel@hashicorp.com>
* PKI migration writes out empty migration log entry
- Since the elements of the struct were not exported we serialized an empty
migration log to disk and would re-run the migration
* Add chain-building logic to PKI issuers path
With the one-entry-per-issuer approach, CA Chains become implicitly
constructed from the pool of issuers. This roughly matches the existing
expectations from /config/ca (wherein a chain could be provided) and
/intemediate/set-signed (where a chain may be provided). However, in
both of those cases, we simply accepted a chain. Here, we need to be
able to reconstruct the chain from parts on disk.
However, with potential rotation of roots, we need to be aware of
disparate chains. Simply concating together all issuers isn't
sufficient. Thus we need to be able to parse a certificate's Issuer and
Subject field and reconstruct valid (and potentially parallel)
parent<->child mappings.
This attempts to handle roots, intermediates, cross-signed
intermediates, cross-signed roots, and rotated keys (wherein one might
not have a valid signature due to changed key material with the same
subject).

* Return CA Chain when fetching issuers
This returns the CA Chain attribute of an issuer, showing its computed
chain based on other issuers in the database, when fetching a specific
issuer.
Signed-off-by: Alexander Scheel <alex.scheel@hashicorp.com>
* Add testing for chain building
Using the issuance infrastructure, we generate new certificates (either
roots or intermediates), positing that this is roughly equivalent to
importing an external bundle (minus error handling during partial
imports). This allows us to incrementally construct complex chains,
creating reissuance cliques and cross-signing cycles.
By using ECDSA certificates, we avoid high signature verification and
key generation times.

* Allow manual construction of issuer chain
Signed-off-by: Alexander Scheel <alex.scheel@hashicorp.com>
* Fix handling of duplicate names
With the new issuer field (manual_chain), we can no longer err when a
name already exists: we might be updating the existing issuer (with the
same name), but changing its manual_chain field. Detect this error and
correctly handle it.
Signed-off-by: Alexander Scheel <alex.scheel@hashicorp.com>
* Add tests for manual chain building
We break the clique, instead building these chains manually, ensuring
that the remaining chains do not change and only the modified certs
change. We then reset them (back to implicit chain building) and ensure
we get the same results as earlier.
Signed-off-by: Alexander Scheel <alex.scheel@hashicorp.com>
* Add stricter verification of issuers PEM format
This ensures each issuer is only a single certificate entry (as
validated by count and parsing) without any trailing data.
We further ensure that each certificate PEM has leading and trailing
spaces removed with only a single trailing new line remaining.
Signed-off-by: Alexander Scheel <alex.scheel@hashicorp.com>
* Fix full chain building
Don't set the legacy IssuingCA field on the certificate bundle, as we
prefer the CAChain field over it.
Additionally, building the full chain could result in duplicate
certificates when the CAChain included the leaf certificate itself. When
building the full chain, ensure we don't include the bundle's
certificate twice.

* Rename PKI types to avoid constant variable name collisions
keyId -> keyID
issuerId -> issuerID
key -> keyEntry
issuer -> issuerEntry
keyConfig -> keyConfigEntry
issuerConfig -> issuerConfigEntry
* Update CRL handling for multiple issuers
When building CRLs, we've gotta make sure certs issued by that issuer
land up on that issuer's CRL and not some other CRL. If no CRL is
found (matching a cert), we'll place it on the default CRL.
However, in the event of equivalent issuers (those with the same subject
AND the same key material) -- perhaps due to reissuance -- we'll only
create a single (unified) CRL for them.

CRL.

* Remove legacy CRL storage location test case
Signed-off-by: Alexander Scheel <alex.scheel@hashicorp.com>
* Update to CRLv2 Format to copy RawIssuer
When using the older Certificate.CreateCRL(...) call, Go's x509 library
copies the parsed pkix.Name version of the CRL Issuer's Subject field.
For certain constructed CAs, this fails since pkix.Name is not suitable
for round-tripping. This also builds a CRLv1 (per RFC 5280) CRL.
In updating to the newer x509.CreateRevocationList(...) call, we can
construct the CRL in the CRLv2 format and correctly copy the issuer's
name. However, this requires holding an additional field per-CRL, the
CRLNumber field, which is required in Go's implementation of CRLv2
(though OPTIONAL in the spec). We store this on the new
LocalCRLConfigEntry object, per-CRL.

* Add new PKI key prefix to seal wrapped storage (#15126)
* Refactor common backend initialization within backend_test
- Leverage an existing helper method within the PKI backend tests to setup a PKI backend with storage.
* Add ability to read legacy cert bundle if the migration has not occurred on secondaries.
- Track the migration state forbidding an issuer/key writing api call if we have not migrated
- For operations that just need to read the CA bundle, use the same tracking variable to
switch between reading the legacy bundle or use the new key/issuer storage.
- Add an invalidation function that will listen for updates to our log path to refresh the state
on secondary clusters.
* Always write migration entry to trigger secondary clusters to wake up
- Some PR feedback and handle a case in which the primary cluster does
not have a CA bundle within storage but somehow a secondary does.
* Update CA Chain to report entire chain
This merges the ca_chain JSON field (of the /certs/ca_chain path) with
the regular certificate field, returning the root of trust always. This
also affects the non-JSON (raw) endpoints as well.
We return the default issuer's chain here, rather than all known issuers
(as that may not form a strict chain).

* Allow explicit issuer override on roles
When a role is used to generate a certificate (such as with the sign/
and issue/ legacy paths or the legacy sign-verbatim/ paths), we prefer
that issuer to the one on the request. This allows operators to set an
issuer (other than default) for requests to be issued against,
effectively making the change no different from the users' perspective
as it is "just" a different role name.

* Expand NotAfter limit enforcement behavior
Vault previously strictly enforced NotAfter/ttl values on certificate
requests, erring if the requested TTL extended past the NotAfter date of
the issuer. In the event of issuing an intermediate, this behavior was
ignored, instead permitting the issuance.
Users generally do not think to check their issuer's NotAfter date when
requesting a certificate; thus this behavior was generally surprising.
Per RFC 5280 however, issuers need to maintain status information
throughout the life cycle of the issued cert. If this leaf cert were to
be issued for a longer duration than the parent issuer, the CA must
still maintain revocation information past its expiration.
Thus, we add an option to the issuer to change the desired behavior:
- err, to err out,
- permit, to permit the longer NotAfter date, or
- truncate, to silently truncate the expiration to the issuer's
NotAfter date.
Since expiration of certificates in the system's trust store are not
generally validated (when validating an arbitrary leaf, e.g., during TLS
validation), permit should generally only be used in that case. However,
browsers usually validate intermediate's validity periods, and thus
truncate should likely be used (as with permit, the leaf's chain will
not validate towards the end of the issuance period).

The backend Framework has updated Callbacks (used extensively in PKI) to

We switch to the new format everywhere, updating some bad assumptions
about forwarding along the way. Anywhere writes are handled (that should
be propagated to all nodes in all clusters), we choose to forward the
request all the way up to the performance primary cluster's primary
node. This holds for issuers/keys, roles, and configs (such as CRL
config, which is globally set for all clusters despite all clusters

VAULT-5827 Don't prepare SQL queries before executing them
We don't support proper prepared statements, i.e., preparing once and
executing many times since we do our own templating. So preparing our
queries does not really accomplish anything, and can have severe
performance impacts (see
https://github.com/hashicorp/vault-plugin-database-snowflake/issues/13
for example).
This behavior seems to have been copy-pasted for many years but not for
any particular reason that we have been able to find. First use was in
https://github.com/hashicorp/vault/pull/15
So here we switch to new methods suffixed with `Direct` to indicate
that they don't `Prepare` before running `Exec`, and switch everything
here to use those. We maintain the older methods with the existing
behavior (with `Prepare`) for backwards compatibility.

When adding SignatureBits control logic, we incorrectly allowed
specification of SignatureBits in the case of an ECDSA issuer. As noted
in the original request, NIST and Mozilla (and others) are fairly
prescriptive in the choice of signatures (matching the size of the
NIST P-curve), and we shouldn't usually use a smaller (or worse, larger
and truncate!) hash.
Ignore the configuration of signature bits and always use autodetection
for ECDSA like ed25519.

* Add PKI test for delete role
- Create a role, validate that defaults are what we expect
and delete the role, verifying it is gone on subsequent read
attempts.
* Add PKI test for crl/rotate command
- Missing a unit test that validates the crl/rotate command works. The test validates the rotate command was successful
by checking if we have a different/new update time on the CRL.

* Additional PR feedback
* Correctly handle minimums, default SignatureBits
When using KeyType = "any" on a role (whether explicitly or implicitly
via a sign-verbatim like operation), we need to update the value of
SignatureBits from its new value 0 to a per-key-type default value. This
will allow sign operations on these paths to function correctly, having
the correctly inferred default signature bit length.
Additionally, this allows the computed default value for key type to be
used for minimum size validation in the RSA/ECDSA paths. We additionally
enforce the 2048-minimum in this case as well.

* Fix defaults and validation of "any" KeyType
When certutil is given the placeholder any keytype, it attempts to
validate and update the default zero value. However, in lacking a
default value for SignatureBits, it cannot update the value from the
zero value, thus causing validation to fail.
Add more awareness to the placeholder "any" value to certutil.

The URL password redaction operation did not handle the case where the

its password component contained reserved characters. It attempted to

Instead of using the field FieldData.Raw, use method GetOkError() which does
type conversion but still allows to check whether a value for the parameter was
provided. Note that GetOkError() converts nil values to default or zero values,
so, for example, a nil plaintext value will result in the empty string being
encrypted.

* Refactor sanitizedName to reducedName
Per comment, this variable name was confusing during the reproduction

but portions of the entire name are removed, reducedName appears to make

* Enforce AllowWildcardCertificates during issuance
This commit adds the bulk of correctly validating wildcard certificate
Common Names during issuance according to RFC 6125 Section 6.4.3
semantics. As part of this, support for RFC 2818-conforming wildcard
certificates (wherein there are almost no restrictions on issuance) has
been removed.
Note that this flag does take precedence over AllowAnyName, giving a
little more safety in wildcard issuance in this case.

* Update test cases to conform with RFC 6125
Test cases 19, 70+71, and 83+84 didn't conform with the RFC 6125, and so
should've been rejected under strict conformance. For 70+71 and 83+84,
we previously conditioned around the value of AllowSubdomains (allowing
issuance when true), but they likely should've been rejected either way.
Additionally, update the notes about globs matching wildcard
certificates to notate this is indeed the case.

* Check AllowWildcardCertifciates in issuance tests

* Allow issuance of wildcard via glob match
From Vault v1.8.0 onwards, we would incorrectly disallow issuance of a
wildcard certificate when allow_glob_domain was enabled with a
multi-part glob domain in allowed_domains (such as *.*.foo) when
attempting to issue a wildcard for a subdomain (such as *.bar.foo).
This fixes that by reverting an errant change in the case insensitivity
patch. Here, when validating against a very powerful glob construct, we
leave the wildcard prefix (*.) from the raw common_name element, to
allow multi-part globs to match wildcard entries.
It is important to note that "sanitizedName" is an incorrect variable
naming here. Wildcard parsing (per RFC 6125 which supercedes RFC 2818)
must be in the left-most segment of the domain, but we lack validation
to ensure no internal wildcards exist. Additionally per item 3 of
section 6.4.3 of RFC 6125, wildcards MAY be internal to a domain
segment, in which case sanitizedName again leaves the wildcard in place.

This commit introduces multi-dimensional testing of PKI secrets engine's
role-based certificate issuance with the intent of preventing future
regressions.
Here, dimensions of testing include:
- AllowedDomains to decide which domains are approved for issuance,
- AllowBareDomains to decide if raw entries of AllowedDomains are
permitted,
- AllowGlobDomains to decide if glob patterns in AllowedDomains are
parsed,
- AllowSubdomains to decide if subdomains of AllowedDomains are
permitted,
- AllowLocalhost to decide if localhost identifiers are permitted, and
- CommonName of the certificate to request.

* Add checks for other error types within the PKI plugin
- The PKI plugin assumes the code it is calling always returns an error
of type errutil.UserError or errutil.InternalError. While I believe
so far this is still true, it would be easy to add a code path that
just returns a generic error and we would completely ignore it.
- This was found within some managed key testing where I forgot to wrap
an error within one of the expected types

* Allow OpenSSH-style key type identifiers
To bring better parity with the changes of #14008, wherein we allowed
OpenSSH-style key identifiers during generation. When specifying a list
of allowed keys, validate against both OpenSSH-style key identifiers
and the usual simplified names as well ("rsa" or "ecdsa"). Notably, the
PKI secrets engine prefers "ec" over "ecdsa", so we permit both as well.

In the ssh secrets engine, only a single allowed key length was allowed

values (such as RSA and ECDSA); allowing a single role to have multiple
values for a single algorithm is thus helpful.
On creation or update, roles can now specify multiple types using a list
or comma separated string of allowed values:
allowed_user_key_lengths: map[string][]int{"rsa": []int{2048, 4096}}

OpenSSH RFC 8709 format. As mentioned in this dependency's README,
support in golang.org/x/crypto/ssh is presently lacking for this.
When the associated CL is merged, we should be able to remove this dep
and rely on the (extended) standard library, however, no review progress
appears to have been made since the CL was opened by the author.
