◆ Decrypt()

virtual bool NetworkEncryptionHandler::Decrypt ( std::span< std::uint8_t >  mac,
std::span< std::uint8_t >  message 
)
pure virtual

Decrypt the given message in-place, validating against the given MAC.

Parameters
macThe message authentication code (MAC).
messageThe location of the message to decrypt.
Returns
Whether decryption and authentication/validation of the message succeeded.

Implemented in X25519EncryptionHandler.

◆ Encrypt()

virtual void NetworkEncryptionHandler::Encrypt ( std::span< std::uint8_t >  mac,
std::span< std::uint8_t >  message 
)
pure virtual

Encrypt the given message in-place, and write the associated MAC.

Parameters
macThe location to write the message authentication code (MAC) to.
messageThe location of the message to encrypt.

Implemented in X25519EncryptionHandler.

◆ MACSize()

virtual size_t NetworkEncryptionHandler::MACSize ( ) const
pure virtual

Get the size of the MAC (Message Authentication Code) used by the underlying encryption protocol.

Returns
The size, in bytes, of the MACs.

Implemented in X25519EncryptionHandler.
