This operation allows a security object to be encrypted by another key for export and transfer out of Fortanix DSM to other systems.
Requirements:
- The target key to be wrapped, need to be marked Exportable.
- The wrapping key needs to have WRAPKEY operation enabled.
- Symmetric keys (AES, DES, DES3), HMAC keys, Opaque objects, and Secret objects can be wrapped with other symmetric or asymmetric keys.
- Note: Asymmetric Keys (RSA/DSA), cannot wrap keys/secrets with a size larger than the key size.
- Asymmetric keys (RSA/DSA) can be wrapped with symmetric keys (AES etc) only. Wrapping an asymmetric key with an asymmetric key is not supported.
- The wrapping parameters will follow the same guidelines as general Encryption operation by the wrapping key. See the Encryption section for more details.
