Detailed Description

Interface for AEAD (Authenticated Encryption with Associated Data) modes. These modes provide both encryption and message authentication, and can authenticate additional per-message data which is not included in the ciphertext (for instance a sequence number).

Member Function Documentation

◆ associated_data_requires_key()

virtual bool Botan::AEAD_Mode::associated_data_requires_key ( ) const
inlinevirtual

Most AEADs require the key to be set prior to setting the AD A few allow the AD to be set even before the cipher is keyed. Such ciphers would return false from this function.

Reimplemented in Botan::ChaCha20Poly1305_Mode, and Botan::CCM_Mode.

◆ authenticated()

bool Botan::AEAD_Mode::authenticated ( ) const

Returns
true iff this mode provides authentication as well as confidentiality.

Reimplemented from Botan::Cipher_Mode.

Process message blocks

Input must be a multiple of update_granularity

Processes msg in place and returns bytes written. Normally this will be either msg_len (indicating the entire message was processed) or for certain AEAD modes zero (indicating that the mode requires the entire message be processed in one pass).

Parameters
msgthe message to be processed
msg_lenlength of the message in bytes

Implemented in Botan::OCB_Decryption, Botan::CBC_Decryption, Botan::EAX_Decryption, Botan::GCM_Decryption, Botan::OCB_Encryption, Botan::CFB_Decryption, Botan::ChaCha20Poly1305_Decryption, Botan::XTS_Decryption, Botan::EAX_Encryption, Botan::GCM_Encryption, Botan::CBC_Encryption, Botan::CFB_Encryption, Botan::ChaCha20Poly1305_Encryption, Botan::XTS_Encryption, Botan::TLS::TLS_CBC_HMAC_AEAD_Mode, Botan::SIV_Mode, and Botan::CCM_Mode.

Set associated data that is not included in the ciphertext but that should be authenticated. Must be called after set_key and before start.

Unless reset by another call, the associated data is kept between messages. Thus, if the AD does not change, calling once (after set_key) is the optimum.

Parameters
