--- layout: "api" page_title: "Transit - Secrets Engines - HTTP API" sidebar_current: "docs-http-secret-transit" description: |- This is the API documentation for the Vault Transit secrets engine. --- # Transit Secrets Engine (API) This is the API documentation for the Vault Transit secrets engine. For general information about the usage and operation of the Transit secrets engine, please see the [transit documentation](/docs/secrets/transit/index.html). This documentation assumes the transit secrets engine is enabled at the `/transit` path in Vault. Since it is possible to enable secrets engines at any location, please update your API calls accordingly. ## Create Key This endpoint creates a new named encryption key of the specified type. The values set here cannot be changed after key creation. | Method | Path | Produces | | :------- | :--------------------------- | :--------------------- | | `POST` | `/transit/keys/:name` | `204 (empty body)` | ### Parameters - `name` `(string: )` – Specifies the name of the encryption key to create. This is specified as part of the URL. - `convergent_encryption` `(bool: false)` – If enabled, the key will support convergent encryption, where the same plaintext creates the same ciphertext. This requires _derived_ to be set to `true`. When enabled, each encryption(/decryption/rewrap/datakey) operation will derive a `nonce` value rather than randomly generate it. - `derived` `(bool: false)` – Specifies if key derivation is to be used. If enabled, all encrypt/decrypt requests to this named key must provide a context which is used for key derivation. - `exportable` `(bool: false)` - Enables keys to be exportable. This allows for all the valid keys in the key ring to be exported. Once set, this cannot be disabled. - `allow_plaintext_backup` `(bool: false)` - If set, enables taking backup of named key in the plaintext format. Once set, this cannot be disabled. - `type` `(string: "aes256-gcm96")` – Specifies the type of key to create. The currently-supported types are: - `aes256-gcm96` – AES-256 wrapped with GCM using a 96-bit nonce size AEAD (symmetric, supports derivation and convergent encryption) - `chacha20-poly1305` – ChaCha20-Poly1305 AEAD (symmetric, supports derivation and convergent encryption) - `ed25519` – ED25519 (asymmetric, supports derivation). When using derivation, a sign operation with the same context will derive the same key and signature; this is a signing analogue to `convergent_encryption`. - `ecdsa-p256` – ECDSA using the P-256 elliptic curve (asymmetric) - `rsa-2048` - RSA with bit size of 2048 (asymmetric) - `rsa-4096` - RSA with bit size of 4096 (asymmetric) ### Sample Payload ```json { "type": "ecdsa-p256", "derived": true } ``` ### Sample Request ``` $ curl \ --header "X-Vault-Token: ..." \ --request POST \ --data @payload.json \ http://127.0.0.1:8200/v1/transit/keys/my-key ``` ## Read Key This endpoint returns information about a named encryption key. The `keys` object shows the creation time of each key version; the values are not the keys themselves. Depending on the type of key, different information may be returned, e.g. an asymmetric key will return its public key in a standard format for the type. | Method | Path | Produces | | :------- | :--------------------------- | :--------------------- | | `GET` | `/transit/keys/:name` | `200 application/json` | ### Parameters - `name` `(string: )` – Specifies the name of the encryption key to read. This is specified as part of the URL. ### Sample Request ``` $ curl \ --header "X-Vault-Token: ..." \ http://127.0.0.1:8200/v1/transit/keys/my-key ``` ### Sample Response ```json { "data": { "type": "aes256-gcm96", "deletion_allowed": false, "derived": false, "exportable": false, "allow_plaintext_backup": false, "keys": { "1": 1442851412 }, "min_decryption_version": 1, "min_encryption_version": 0, "name": "foo", "supports_encryption": true, "supports_decryption": true, "supports_derivation": true, "supports_signing": false } } ``` ## List Keys This endpoint returns a list of keys. Only the key names are returned (not the actual keys themselves). | Method | Path | Produces | | :------- | :--------------------------- | :--------------------- | | `LIST` | `/transit/keys` | `200 application/json` | ### Sample Request ``` $ curl \ --header "X-Vault-Token: ..." \ --request LIST \ http://127.0.0.1:8200/v1/transit/keys ``` ### Sample Response ```json { "data": { "keys": ["foo", "bar"] }, "lease_duration": 0, "lease_id": "", "renewable": false } ``` ## Delete Key This endpoint deletes a named encryption key. It will no longer be possible to decrypt any data encrypted with the named key. Because this is a potentially catastrophic operation, the `deletion_allowed` tunable must be set in the key's `/config` endpoint. | Method | Path | Produces | | :------- | :--------------------------- | :--------------------- | | `DELETE` | `/transit/keys/:name` | `204 (empty body)` | ### Parameters - `name` `(string: )` – Specifies the name of the encryption key to delete. This is specified as part of the URL. ### Sample Request ``` $ curl \ --header "X-Vault-Token: ..." \ --request DELETE \ http://127.0.0.1:8200/v1/transit/keys/my-key ``` ## Update Key Configuration This endpoint allows tuning configuration values for a given key. (These values are returned during a read operation on the named key.) | Method | Path | Produces | | :------- | :--------------------------- | :--------------------- | | `POST` | `/transit/keys/:name/config` | `204 (empty body)` | ### Parameters - `min_decryption_version` `(int: 0)` – Specifies the minimum version of ciphertext allowed to be decrypted. Adjusting this as part of a key rotation policy can prevent old copies of ciphertext from being decrypted, should they fall into the wrong hands. For signatures, this value controls the minimum version of signature that can be verified against. For HMACs, this controls the minimum version of a key allowed to be used as the key for verification. - `min_encryption_version` `(int: 0)` – Specifies the minimum version of the key that can be used to encrypt plaintext, sign payloads, or generate HMACs. Must be `0` (which will use the latest version) or a value greater or equal to `min_decryption_version`. - `deletion_allowed` `(bool: false)` - Specifies if the key is allowed to be deleted. - `exportable` `(bool: false)` - Enables keys to be exportable. This allows for all the valid keys in the key ring to be exported. Once set, this cannot be disabled. - `allow_plaintext_backup` `(bool: false)` - If set, enables taking backup of named key in the plaintext format. Once set, this cannot be disabled. ### Sample Payload ```json { "deletion_allowed": true } ``` ### Sample Request ``` $ curl \ --header "X-Vault-Token: ..." \ --request POST \ --data @payload.json \ http://127.0.0.1:8200/v1/transit/keys/my-key/config ``` ## Rotate Key This endpoint rotates the version of the named key. After rotation, new plaintext requests will be encrypted with the new version of the key. To upgrade ciphertext to be encrypted with the latest version of the key, use the `rewrap` endpoint. This is only supported with keys that support encryption and decryption operations. | Method | Path | Produces | | :------- | :--------------------------- | :--------------------- | | `POST` | `/transit/keys/:name/rotate` | `204 (empty body)` | ### Sample Request ``` $ curl \ --header "X-Vault-Token: ..." \ --request POST \ http://127.0.0.1:8200/v1/transit/keys/my-key/rotate ``` ## Export Key This endpoint returns the named key. The `keys` object shows the value of the key for each version. If `version` is specified, the specific version will be returned. If `latest` is provided as the version, the current key will be provided. Depending on the type of key, different information may be returned. The key must be exportable to support this operation and the version must still be valid. | Method | Path | Produces | | :------- | :--------------------------- | :--------------------- | | `GET` | `/transit/export/:key_type/:name(/:version)` | `200 application/json` | ### Parameters - `key_type` `(string: )` – Specifies the type of the key to export. This is specified as part of the URL. Valid values are: - `encryption-key` - `signing-key` - `hmac-key` - `name` `(string: )` – Specifies the name of the key to read information about. This is specified as part of the URL. - `version` `(string: "")` – Specifies the version of the key to read. If omitted, all versions of the key will be returned. This is specified as part of the URL. If the version is set to `latest`, the current key will be returned. ### Sample Request ``` $ curl \ --header "X-Vault-Token: ..." \ http://127.0.0.1:8200/v1/transit/export/encryption-key/my-key/1 ``` ### Sample Response ```json { "data": { "name": "foo", "keys": { "1": "eyXYGHbTmugUJn6EtYD/yVEoF6pCxm4R/cMEutUm3MY=", "2": "Euzymqx6iXjS3/NuGKDCiM2Ev6wdhnU+rBiKnJ7YpHE=" } } } ``` ## Encrypt Data This endpoint encrypts the provided plaintext using the named key. This path supports the `create` and `update` policy capabilities as follows: if the user has the `create` capability for this endpoint in their policies, and the key does not exist, it will be upserted with default values (whether the key requires derivation depends on whether the context parameter is empty or not). If the user only has `update` capability and the key does not exist, an error will be returned. | Method | Path | Produces | | :------- | :--------------------------- | :--------------------- | | `POST` | `/transit/encrypt/:name` | `200 application/json` | ### Parameters - `name` `(string: )` – Specifies the name of the encryption key to encrypt against. This is specified as part of the URL. - `plaintext` `(string: )` – Specifies **base64 encoded** plaintext to be encoded. - `context` `(string: "")` – Specifies the **base64 encoded** context for key derivation. This is required if key derivation is enabled for this key. - `key_version` `(int: 0)` – Specifies the version of the key to use for encryption. If not set, uses the latest version. Must be greater than or equal to the key's `min_encryption_version`, if set. - `nonce` `(string: "")` – Specifies the **base64 encoded** nonce value. This must be provided if convergent encryption is enabled for this key and the key was generated with Vault 0.6.1. Not required for keys created in 0.6.2+. The value must be exactly 96 bits (12 bytes) long and the user must ensure that for any given context (and thus, any given encryption key) this nonce value is **never reused**. - `batch_input` `(array: nil)` – Specifies a list of items to be encrypted in a single batch. When this parameter is set, if the parameters 'plaintext', 'context' and 'nonce' are also set, they will be ignored. The format for the input is: ```json [ { "context": "c2FtcGxlY29udGV4dA==", "plaintext": "dGhlIHF1aWNrIGJyb3duIGZveA==" }, { "context": "YW5vdGhlcnNhbXBsZWNvbnRleHQ=", "plaintext": "dGhlIHF1aWNrIGJyb3duIGZveA==" }, ] ``` - `type` `(string: "aes256-gcm96")` –This parameter is required when encryption key is expected to be created. When performing an upsert operation, the type of key to create. - `convergent_encryption` `(string: "")` – This parameter will only be used when a key is expected to be created. Whether to support convergent encryption. This is only supported when using a key with key derivation enabled and will require all requests to carry both a context and 96-bit (12-byte) nonce. The given nonce will be used in place of a randomly generated nonce. As a result, when the same context and nonce are supplied, the same ciphertext is generated. It is _very important_ when using this mode that you ensure that all nonces are unique for a given context. Failing to do so will severely impact the ciphertext's security. ### Sample Payload ```json { "plaintext": "dGhlIHF1aWNrIGJyb3duIGZveA==" } ``` ### Sample Request ``` $ curl \ --header "X-Vault-Token: ..." \ --request POST \ --data @payload.json \ http://127.0.0.1:8200/v1/transit/encrypt/my-key ``` ### Sample Response ```json { "data": { "ciphertext": "vault:v1:abcdefgh" } } ``` ## Decrypt Data This endpoint decrypts the provided ciphertext using the named key. | Method | Path | Produces | | :------- | :--------------------------- | :--------------------- | | `POST` | `/transit/decrypt/:name` | `200 application/json` | ### Parameters - `name` `(string: )` – Specifies the name of the encryption key to decrypt against.

Optionally return the plaintext of the key as well. Whether plaintext is returned depends on the path; as a result, you can use Vault ACL policies to control whether a user is allowed to retrieve the plaintext value of a key. This is useful if you want an untrusted user or operation to generate keys that are then made available to trusted users. | Method | Path | Produces | | :------- | :--------------------------- | :--------------------- | | `POST` | `/transit/datakey/:type/:name` | `200 application/json` | ### Parameters - `type` `(string: )` – Specifies the type of key to generate.
