2499 As of LibTomCrypt v1.15, XCBC-MAC (RFC 3566) has been provided to support TLS encryption suites. Like OMAC, it computes a message authentication code
2500 by using a cipher in CBC mode. It also uses a single key which it expands into the requisite three keys for the MAC function. A XCBC--MAC state is
2503 \index{xcbc\_init()}
2505 int xcbc_init( xcbc_state *xcbc,
2511 This will initialize the XCBC--MAC state \textit{xcbc}, with the key specified in \textit{key} of length \textit{keylen} octets. The cipher indicated
2514 To process data through XCBC--MAC use the following function:
2516 \index{xcbc\_process()}
2523 This will add the message octets pointed to by \textit{in} of length \textit{inlen} to the XCBC--MAC state pointed to by \textit{state}. Like the other MAC functions,
2528 \index{xcbc\_done()}
2535 This will retrieve the XCBC--MAC tag from the state pointed to by \textit{state}, and store it in the array pointed to by \textit{out}. The \textit{outlen} parameter
2540 \index{xcbc\_memory()}
2548 This will compute the XCBC--MAC of \textit{msglen} bytes of \textit{msg}, using the key \textit{key} of length \textit{keylen} bytes, and the cipher
2549 specified by the \textit{cipher}'th entry in the cipher\_descriptor table. It will store the MAC in \textit{out} with the same rules as xcbc\_done().
2551 To xcbc a file use
2552 \index{xcbc\_file()}
2561 Which will XCBC--MAC the entire contents of the file specified by \textit{filename} using the key \textit{key} of length \textit{keylen} bytes, and the cipher
2562 specified by the \textit{cipher}'th entry in the cipher\_descriptor table. It will store the MAC in \textit{out} with the same rules as xcbc\_done().
2565 To test XCBC--MAC for RFC 3566 compliance use the following function:
2567 \index{xcbc\_test()}
5600 /** Accelerated one shot XCBC
5747 \subsubsection{Accelerated XCBC-MAC}
5748 \index{xcbc\_memory()}
5749 This function is meant to perform an optimized XCBC-MAC message authentication code computation when the user calls xcbc\_memory().
