Object-safe trait for key types which perform AEAD encryption

Required Methods

fn encrypt_in_place( &self, buffer: &mut dyn ResizeBuffer, nonce: &[u8], aad: &[u8], ) -> Result<usize, Error>

Encrypt a secret value in place, appending the verification tag and returning the length of the ciphertext

fn decrypt_in_place( &self, buffer: &mut dyn ResizeBuffer, nonce: &[u8], aad: &[u8], ) -> Result<(), Error>

Decrypt an encrypted (verification tag appended) value in place

fn aead_params(&self) -> KeyAeadParams

Get the nonce and tag length for encryption

Provided Methods

fn aead_padding(&self, _msg_len: usize) -> usize

Get the ciphertext padding required

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
