Rebase #14178 / Add not_before_duration API parameter to Root/Intermediate CA generation (#15511)
* PKI - Add not_before_duration API parameter to:
  - Root CA generation
  - Intermediate CA generation
  - Intermediate CA signing

* Move not_before_duration to addCACommonFields

This gets applied on both root generation and intermediate signing,
which is the correct place to apply this.

Allow Multiple Issuers in PKI Secret Engine Mounts - PKI Pod (#15277)
* 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.

* 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.

* 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).

* 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.

* 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.

* 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.

* 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.

* Add stricter tests for full chain construction

* 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.

* Allow fetching the specified issuer's CRL

We add a new API endpoint to fetch the specified issuer's CRL directly

add a new test to validate the CRL in a multi-root scenario and ensure
it is signed with the correct keys.

* 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.

Signed-off-by: Alexander Scheel <alex.scheel@hashicorp.com>

* 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).

* Update PKI to new Operations framework (#15180)

The backend Framework has updated Callbacks (used extensively in PKI) to
become deprecated; Operations takes their place and clarifies forwarding
of requests.

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
having their own separate CRL).

* Remove deleted issuers' CRL entries

Since CRLs are no longer resolvable after deletion (due to missing

In the event that this issuer comes back (with key material), we can
simply rebuild the CRL at that time (from the remaining revoked storage
entries).

* Add issuer usage restrictions bitset

This allows issuers to have usage restrictions, limiting whether they
can be used to issue certificates or if they can generate CRLs. This
allows certain issuers to not generate a CRL (if the global config is

(but potentially letting the CRL generation continue).

Setting both fields to false effectively forms a soft delete capability.

Sync PKI API and FrameworkField descriptions (#14286)
As pointed out internally, a lot of the API docs and FrameworkField
descriptions of parameters were out of date. This syncs a number of
them, updating their descriptions where relevant.

Add universal default key_bits value for PKI endpoints (#13080)
* Allow universal default for key_bits

This allows the key_bits field to take a universal default value, 0,
which, depending on key_type, gets adjusted appropriately into a
specific default value (rsa->2048, ec->256, ignored under ed25519).

* Re-add fix for ed25519 from #13254

Ed25519 internally specifies a hash length; by changing the default from
256 to 0, we fail validation in ValidateSignatureLength(...) unless we
specify the key algorithm.

Restrict ECDSA/NIST P-Curve hash function sizes for cert signing (#12872)
* Restrict ECDSA signatures with NIST P-Curve hashes

When using an ECDSA signature with a NIST P-Curve, we should follow
recommendations from BIS (Section 4.2) and Mozilla's root store policy
(section 5.1.2) to ensure that arbitrary selection of signature_bits
does not exceed what the curve is capable of signing.

* Switch to certutil.ValidateKeyTypeSignatureLength(...)

Replaces previous calls to certutil.ValidateKeyTypeLength(...) and
certutil.ValidateSignatureLength(...) with a single call, allowing for
curve<->hash validation.

Signed-off-by: Alexander Scheel <alex.scheel@hashicorp.com>

* Switch to autodetection of signature_bits

This enables detection of whether the caller manually specified a value
for signature_bits or not; when not manually specified, we can provision
a value that complies with new NIST P-Curve policy.

Signed-off-by: Alexander Scheel <alex.scheel@hashicorp.com>

* Select hash function length automatically

Due to our change in behavior (to default to -1 as the value to
signature_bits to allow for automatic hash selection), switch
ValidateKeyTypeSignatureLength(...) to accept a pointer to hashBits and
provision it with valid default values.

improvement: add signature_bits field to CA and signers (#11245)
This change adds the ability to set the signature algorithm of the
CAs that Vault generates and any certificates it signs.  This is a
potentially useful stepping stone for a SHA3 transition down the line.

Summary:
* Adds the field "signature_bits" to CA and Sign endpoints
* Adds support for SHA256, SHA384 and SHA512 signatures on EC and RSA
keytypes.

Among other things this now means PKI will output durations in seconds

* Add a warning when refusing to blow away an existing root instead of just returning success

* Fix another issue found while debugging this...

The reason it wasn't caught on tests in the first place is that the ttl
and max ttl were only being compared if in addition to a provided csr, a
role was also provided. This was because the check was in the role !=
nil block instead of outside of it. This has been fixed, which made the
problem occur in all sign-verbatim cases and the changes in this PR have
now verified the fix.
