inline

AES Key Unwrap — recovers plaintext key material from wrapped form.

Parameters

kek	256-bit Key Encryption Key
ciphertext	Wrapped key (must be multiple of 8 bytes, >= 24)

Returns

Unwrapped key material, or error if integrity check fails

inline

AES Key Wrap — wraps plaintext key material under a KEK.

Parameters

kek	256-bit Key Encryption Key
plaintext	Key material to wrap (must be multiple of 8 bytes, >= 16)

Returns
