Struct DecryptionContext 

pub struct DecryptionContext(/* private fields */);

A block cipher state and AEAD mode for decryption.

Implementations

impl DecryptionContext

pub fn decrypt_verify(&mut self, dst: &mut [u8], src: &[u8]) -> Result<()>

Decrypts src to dst.

Decrypts the given plaintext, and checks the authentication tag. If the authentication tag is not correct, an error is returned.

src contains both the ciphertext and the digest, i.e. its length must be exactly dst.len() + self.digest_size().

pub fn digest_size(&self) -> usize

Length of the digest in bytes.
