Implementation of GCM/CCM properties for Encrypt/Seal

Required methods

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

Sets the CCM Additional Authentication Data

• AAD length can have any positive value.
• The total plaintext length must be passed.
• Set after EncryptContext::initialize() / SealContext::initialize() and before EncryptContext::update() / SealContext::update().
• See BlockCipherMode::Ccm for more information.

Provided methods

pub fn set_property_gcm_tag_len(&self, gcm_tag_len: usize) -> Result<()>

Sets the GCM tag length (in bytes)

• Supported tag lengths: 4, 8, 12, 13, 14, 15, 16.
• Set after EncryptContext::finalize() / SealContext::finalize() and before CtxXcmEnc::get_property_gcm_tag().
• See BlockCipherMode::Gcm for more information.

pub fn get_property_gcm_tag(&self) -> Result<Vec<u8>>

Gets the GCM tag

• Get after EncryptContext::finalize() / SealContext::finalize().
• See BlockCipherMode::Gcm for more information.

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

Sets the GCM Additional Authentication Data

• AAD length can have any positive value.
• Set after EncryptContext::initialize() / SealContext::initialize() and before EncryptContext::update() / SealContext::update() in Encryption/Seal operation.
• See BlockCipherMode::Gcm for more information.

pub fn set_property_ccm_tag_len(&self, ccm_tag_len: usize) -> Result<()>

Sets the CCM Tag length in bytes

• Supported tag lengths: 4-16 bytes in steps of 2 bytes.
• Set after EncryptContext::initialize() / SealContext::initialize() and before EncryptContext::update() / SealContext::update().
• See BlockCipherMode::Ccm for more information.

pub fn get_property_ccm_tag(&self) -> Result<Vec<u8>>

Gets the CCM tag

• Get after EncryptContext::finalize() / SealContext::finalize().
• See BlockCipherMode::Ccm for more information.
