In-place stateless AEAD trait.

This trait is both object safe and has no dependencies on alloc or std.

Required methods

fn encrypt_in_place_detached(
    &self,
    nonce: &Nonce<Self>,
    associated_data: &[u8],
    buffer: &mut [u8]
) -> Result<Tag<Self>, Error>

Encrypt the data in-place, returning the authentication tag

fn decrypt_in_place_detached(
    &self,
    nonce: &Nonce<Self>,
    associated_data: &[u8],
    buffer: &mut [u8],
    tag: &Tag<Self>
) -> Result<(), Error>

Decrypt the message in-place, returning an error in the event the provided authentication tag does not match the given ciphertext (i.e. ciphertext is modified/unauthentic)

Provided methods

fn encrypt_in_place(
    &self,
    nonce: &Nonce<Self>,
    associated_data: &[u8],
    buffer: &mut dyn Buffer
) -> Result<(), Error>

Encrypt the given buffer containing a plaintext message in-place.

The buffer must have sufficient capacity to store the ciphertext message, which will always be larger than the original plaintext. The exact size needed is cipher-dependent, but generally includes the size of an authentication tag.

Returns an error if the buffer has insufficient capacity to store the resulting ciphertext message.

fn decrypt_in_place(
    &self,
    nonce: &Nonce<Self>,
    associated_data: &[u8],
    buffer: &mut dyn Buffer
) -> Result<(), Error>

Decrypt the message in-place, returning an error in the event the provided authentication tag does not match the given ciphertext.

The buffer will be truncated to the length of the original plaintext message upon success.
