Decryption interface; implement this on decryption context

This can be the same type as Encryption but does not have to be.

Required Methods

fn init( key_id: u32, key_version: u32, key: &[u8], iv: &[u8], same_size: bool ) -> Result<Self, EncryptionError>

Initialize the decryption context object. See Encryption::init for information on parameters.

fn update( &mut self, src: &[u8], dst: &mut [u8] ) -> Result<usize, EncryptionError>

Update the encryption context with new data, return the number of bytes written.

Provided Methods

fn finish(&mut self, dst: &mut [u8]) -> Result<usize, EncryptionError>

Finish decryption. Usually this performs validation and, in some cases, can be used to write additional data.

If init was called with same_size = true, dst will likely be empty.

Object Safety

This trait is not object safe.
