Implementation of GCM/CCM properties for Decrypt/Open

Required methods

fn set_property_ccm_aad(
    &self,
    ccm_aad: &[u8],
    ciphertext_len: usize
) -> Result<()>

Sets the CCM Additional Authentication Data

• AAD is the same data that is passed during 'Encrypt'/'Seal' operation with CtxXcmEnc::set_property_ccm_aad().
• The total ciphertext length must be passed.
• Set after DecryptContext::initialize() / OpenContext::initialize() and before DecryptContext::update() / OpenContext::update() in Decryption/Open operation.
• See BlockCipherMode::Ccm for more information.

Provided methods

fn set_property_gcm_tag(&self, gcm_tag: &[u8]) -> Result<()>

Sets the GCM tag

• The tag is gotten during 'Encrypt'/'Seal' operation with CtxXcmEnc::get_property_gcm_tag().
• Set after DecryptContext::update() / OpenContext::update() and before DecryptContext::finalize() / OpenContext::finalize().
• See BlockCipherMode::Gcm for more information.

fn set_property_gcm_aad(&self, gcm_aad: &[u8]) -> Result<()>

Sets the GCM Additional Authentication Data

• AAD is the same data that is passed during 'Encrypt'/'Seal' operation with CtxXcmEnc::set_property_gcm_aad().
• Set after DecryptContext::initialize() / OpenContext::initialize() and before DecryptContext::update() / OpenContext::update().
• See BlockCipherMode::Gcm for more information.

fn set_property_ccm_tag(&self, ccm_tag: &[u8]) -> Result<()>

Sets the CCM tag

• The tag is gotten during 'Encrypt'/'Seal' operation with CtxXcmEnc::get_property_ccm_tag().
• Set after DecryptContext::initialize() / OpenContext::initialize() and before DecryptContext::update() / OpenContext::update().
• See BlockCipherMode::Ccm for more information.
