Expand description

Elliptic-curve cryptography interface.

Required Associated Types§

source

type Tag: ArrayLength<u8>

The tag length.

Required Methods§

source

fn encrypt( key: &Array<Key>, iv: &Array<Iv>, aad: &[u8], clear: Option<&[u8]>, cipher: &mut [u8], tag: &mut Array<Self::Tag> ) -> Result<(), Error>

Encrypts and authenticates a clear text with associated data given a key and IV.

The clear- and cipher-texts must have the same length. If the clear text is omitted, then the cipher text is encrypted in place.

source

fn decrypt( key: &Array<Key>, iv: &Array<Iv>, aad: &[u8], cipher: Option<&[u8]>, tag: &Array<Self::Tag>, clear: &mut [u8] ) -> Result<(), Error>

Decrypts and authenticates a cipher text with associated data given a key and IV.

The cipher- and clear-texts must have the same length. If the cipher text is omitted, then the clear text is decrypted in place.

Object Safety§

This trait is not object safe.
