Module bdrck::crypto::key

key defines structures which represent cryptographic keys, and provides some generic code to implement basic operations like encryption and decryption.

Structs

Key

In this module’s terminology, a Key is a cryptographic key of any type which is suitable to use for encryption (i.e., is has not been wrapped).

Nonce

A cryptographic nonce is an arbitrary number that can be used only once (e.g. for encryption).

Constants

KEY_BYTES

xsalsa20poly1305 uses 32 byte keys.

NONCE_BYTES

This module uses xsalsa20poly1305, whose nonces are 24 bytes long.

TAG_BYTES

xsalsa20poly1305 authenticator tags are 16 bytes.

Traits

AbstractKey

An AbstractKey is any cryptographic structure which supports encryption and decryption.
