keys: Encryption keys in Key Vault
In cloudyr/AzureKeyVault: Key and Secret Management in 'Azure'

Description Methods Arguments Value See Also Examples

This class represents the collection of encryption keys stored in a vault. It provides methods for managing keys, including creating, importing and deleting keys, and doing backups and restores. For operations with a specific key, see key.

This class provides the following methods:

create(name, type=c("RSA", "EC"), hardware=FALSE,
       ec_curve=NULL, rsa_key_size=NULL, key_ops=NULL,
       attributes=vault_object_attrs(), ...)
import(name, key, hardware=FALSE,
       attributes=vault_object_attrs(), ...)
get(name)
delete(name, confirm=TRUE)
list(include_managed=FALSE)
backup(name)
restore(backup)

name: The name of the key.
type: For create, the type of key to create: RSA or elliptic curve (EC). Note that for keys backing a certificate, only RSA is allowed.
hardware: For create, Whether to use a hardware key or software key. The former requires a premium key vault.
ec_curve: For an EC key, the type of elliptic curve.
rsa_key_size: For an RSA key, the key size, either 2048, 3072 or 4096.
key_ops: A character vector of operations that the key supports. The possible operations are "encrypt", "decrypt", "sign", "verify", "wrapkey" and "unwrapkey". See key for more information.
attributes: Optional attributes for the key, such as the expiry date and activation date. A convenient way to provide this is via the vault_object_attrs helper function.
key: For import, the key to import. This can be the name of a PEM file, a JSON web key (JWK) string, or a key object generated by the openssl package. See the examples below.
hardware: For import, whether to import this key as a hardware key (HSM). Only supported for a premium key vault.
...: For create and import, other named arguments which will be treated as tags.
include_managed: For list, whether to include keys that were created by Key Vault to support a managed certificate.
backup: For restore, a string representing the backup blob for a key.

For get, create and import, an object of class stored_key, representing the key itself. This has methods for carrying out the operations given by the key_ops argument.

For list, a vector of key names.

For backup, a string representing the backup blob for a key. If the key has multiple versions, the blob will contain all versions.
