pub struct SealingKey<N: NonceSequence> { /* private fields */ }
Expand description

An AEAD key for encrypting and signing (“sealing”), bound to a nonce sequence.

Intentionally not Clone or Copy since cloning would allow duplication of the nonce sequence.

Implementations

👎Deprecated: Renamed to seal_in_place_append_tag.

Deprecated. Renamed to seal_in_place_append_tag().

Encrypts and signs (“seals”) data in place, appending the tag to the resulting ciphertext.

key.seal_in_place_append_tag(aad, in_out) is equivalent to:

key.seal_in_place_separate_tag(aad, in_out.as_mut())
    .map(|tag| in_out.extend(tag.as_ref()))

Encrypts and signs (“seals”) data in place.

aad is the additional authenticated data (AAD), if any. This is authenticated but not encrypted. The type A could be a byte slice &[u8], a byte array [u8; N] for some constant N, Vec<u8>, etc. If there is no AAD then use Aad::empty().

The plaintext is given as the input value of in_out. seal_in_place() will overwrite the plaintext with the ciphertext and return the tag. For most protocols, the caller must append the tag to the ciphertext. The tag will be self.algorithm.tag_len() bytes long.
