Trait aws_nitro_enclaves_cose::crypto::Encryption

pub trait Encryption {
    // Required method
    fn encrypt_aead(
        algo: EncryptionAlgorithm,
        key: &[u8],
        iv: Option<&[u8]>,

}

A trait exposing various aead encryption algorithms.

Required Methods

fn encrypt_aead( algo: EncryptionAlgorithm, key: &[u8], iv: Option<&[u8]>, aad: &[u8], data: &[u8], tag: &mut [u8] ) -> Result<Vec<u8>, CoseError>

Encryption for AEAD ciphers such as AES GCM.

Additional Authenticated Data (AEAD) can be provided in the aad field, and the authentication tag will be copied into the tag field.

The size of the tag buffer indicates the required size of the tag. While some ciphers support a range of tag sizes, it is recommended to pick the maximum size. For AES GCM, this is 16 bytes, for example.

Object Safety

This trait is not object safe.
