Create Key - Create Key

Service:

Key Vault

API Version:

7.4

Creates a new key, stores it, then returns key parameters and attributes to the client.
The create key operation can be used to create any key type in Azure Key Vault. If the named key already exists, Azure Key Vault creates a new version of the key. It requires the keys/create permission.

POST {vaultBaseUrl}/keys/{key-name}/create?api-version=7.4

Error	The key vault server error.
JsonWebKey	As of http://tools.ietf.org/html/draft-ietf-jose-json-web-key-18
JsonWebKeyCurveName	Elliptic curve name. For valid values, see JsonWebKeyCurveName.

JsonWebKeyType	JsonWebKey Key Type (kty), as defined in https://tools.ietf.org/html/draft-ietf-jose-json-web-algorithms-40.
KeyAttributes	The attributes of a key managed by the key vault service.
KeyBundle	A KeyBundle consisting of a WebKey plus its attributes.
KeyCreateParameters	The key create parameters.
KeyReleasePolicy	The policy rules under which the key can be exported.
KeyVaultError	The key vault error exception.

DeletionRecoveryLevel

Reflects the deletion recovery level currently in effect for keys in the current vault. If it contains 'Purgeable' the key can be permanently deleted by a privileged user; otherwise, only the system can purge the key, at the end of the retention interval.

Name	Type	Description
CustomizedRecoverable	string	Denotes a vault state in which deletion is recoverable without the possibility for immediate and permanent deletion (i.e. purge when 7<= SoftDeleteRetentionInDays < 90).This level guarantees the recoverability of the deleted entity during the retention interval and while the subscription is still available.
CustomizedRecoverable+ProtectedSubscription	string	Denotes a vault and subscription state in which deletion is recoverable, immediate and permanent deletion (i.e. purge) is not permitted, and in which the subscription itself cannot be permanently canceled when 7<= SoftDeleteRetentionInDays < 90. This level guarantees the recoverability of the deleted entity during the retention interval, and also reflects the fact that the subscription itself cannot be cancelled.
CustomizedRecoverable+Purgeable	string	Denotes a vault state in which deletion is recoverable, and which also permits immediate and permanent deletion (i.e. purge when 7<= SoftDeleteRetentionInDays < 90). This level guarantees the recoverability of the deleted entity during the retention interval, unless a Purge operation is requested, or the subscription is cancelled.
Purgeable	string	Denotes a vault state in which deletion is an irreversible operation, without the possibility for recovery. This level corresponds to no protection being available against a Delete operation; the data is irretrievably lost upon accepting a Delete operation at the entity level or higher (vault, resource group, subscription etc.)
Recoverable	string	Denotes a vault state in which deletion is recoverable without the possibility for immediate and permanent deletion (i.e. purge). This level guarantees the recoverability of the deleted entity during the retention interval(90 days) and while the subscription is still available. System wil permanently delete it after 90 days, if not recovered
Recoverable+ProtectedSubscription	string	Denotes a vault and subscription state in which deletion is recoverable within retention interval (90 days), immediate and permanent deletion (i.e. purge) is not permitted, and in which the subscription itself cannot be permanently canceled. System wil permanently delete it after 90 days, if not recovered
Recoverable+Purgeable	string	Denotes a vault state in which deletion is recoverable, and which also permits immediate and permanent deletion (i.e. purge). This level guarantees the recoverability of the deleted entity during the retention interval (90 days), unless a Purge operation is requested, or the subscription is cancelled. System wil permanently delete it after 90 days, if not recovered
