Type Alias DryocAeadEnvelope 

pub type DryocAeadEnvelope<Nonce, Mac, Data> = AeadEnvelope<XChaCha20Poly1305Ietf, Nonce, Mac, Data>;

XChaCha20-Poly1305-IETF AEAD envelope with stored nonce.

Aliased Type

pub struct DryocAeadEnvelope<Nonce, Mac, Data> { /* private fields */ }

Implementations

impl DryocAeadEnvelope<Nonce, Mac, Vec<u8>>

pub fn seal_to_vec<Message: Bytes + ?Sized, SecretKey: ByteArray<CRYPTO_AEAD_XCHACHA20POLY1305_IETF_KEYBYTES>>( message: &Message, associated_data: Option<&[u8]>, key: &SecretKey, ) -> Result<Self, Error>

Encrypts a message with a generated nonce and returns a VecEnvelope.

Errors

Returns an error if the message exceeds the construction’s maximum length.

Panics

Panics if the operating system’s random number generator fails.

pub fn open_to_vec<SecretKey: ByteArray<CRYPTO_AEAD_XCHACHA20POLY1305_IETF_KEYBYTES>>( &self, associated_data: Option<&[u8]>, key: &SecretKey, ) -> Result<Vec<u8>, Error>

Decrypts this envelope and returns the plaintext as a Vec.

Errors

Returns an error if the ciphertext exceeds the construction’s maximum length or authentication fails because the key, associated data, stored nonce, ciphertext, or tag does not match.

pub fn into_vec(self) -> Vec<u8>

Consumes this envelope and returns it as nonce || ciphertext || tag.
