Structs

Aes256CbcHmacKey

Aes256CbcHmacKey is a symmetric encryption key consisting of two 256-bit keys, one for encryption and one for MAC

Aes256CbcKey

Aes256CbcKey is a symmetric encryption key, consisting of one 256-bit key, used to decrypt legacy type 0 enc strings. The data is not authenticated so this should be used with caution, and removed where possible.

XChaCha20Poly1305Key

XChaCha20Poly1305Key is a symmetric encryption key consisting of one 256-bit key, and contains a key id. In contrast to the Aes256CbcKey and Aes256CbcHmacKey, this key type is used to create CoseEncrypt0 messages.

Enums

SymmetricCryptoKey

A symmetric encryption key. Used to encrypt and decrypt EncString

Functions

pad_key 🔒

Pad a key to a minimum length using PKCS7-like padding. The last N bytes of the padded bytes all have the value N. For example, padded to size 4, the value 0,0 becomes 0,0,2,2.

unpad_key 🔒

Unpad a key that is padded using the PKCS7-like padding defined by pad_key. The last N bytes of the padded bytes all have the value N. For example, padded to size 4, the value 0,0 becomes 0,0,2,2.
