Member Function Documentation

Decrypt()

bool X25519EncryptionHandler::Decrypt ( std::span< std::uint8_t >  mac, std::span< std::uint8_t >  message  )

inlineoverridevirtual

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

Parameters

mac	The message authentication code (MAC).
message	The location of the message to decrypt.

Returns

Whether decryption and authentication/validation of the message succeeded.

Implements NetworkEncryptionHandler.

Definition at line 124 of file network_crypto.cpp.

Encrypt()

void X25519EncryptionHandler::Encrypt ( std::span< std::uint8_t >  mac, std::span< std::uint8_t >  message  )

inlineoverridevirtual

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

Parameters

mac	The location to write the message authentication code (MAC) to.
message	The location of the message to encrypt.

Implements NetworkEncryptionHandler.

Definition at line 129 of file network_crypto.cpp.

MACSize()

size_t X25519EncryptionHandler::MACSize ( ) const

inlineoverridevirtual

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

Returns

The size, in bytes, of the MACs.

Implements NetworkEncryptionHandler.
