Struct ClearModeCrypto 

pub struct ClearModeCrypto;

A no-op crypto provider for “clear mode” testing.

Per CCSDS 355.0-B-2, a clear-mode SA uses a no-op algorithm so the Security Header and Trailer are present but no actual crypto is performed. Useful for development and integration testing.

Trait Implementations

impl CryptoProvider for ClearModeCrypto

fn encrypt( &self, _sa: &SecurityAssociation, _iv: &[u8], _aad: &[u8], _data: &mut [u8], _tag_out: &mut [u8], ) -> Result<usize, Error>

Encrypt data in place (AEAD). aad is additional authenticated data (frame headers). The authentication tag is written to tag_out. Returns padding byte count (0 for GCM/CTR).

fn decrypt( &self, _sa: &SecurityAssociation, _iv: &[u8], _aad: &[u8], _data: &mut [u8], _tag: &[u8], ) -> Result<usize, Error>

Decrypt data in place (AEAD). Verifies the authentication tag against aad and ciphertext. Returns padding byte count.

fn compute_mac( &self, sa: &SecurityAssociation, _iv: &[u8], _payload: &[u8], mac_out: &mut [u8], ) -> Result<(), Error>

Compute a MAC for authentication-only mode. The iv is passed for algorithms that need it (e.g. GMAC).
