InvCipher                  Library Functions Manual                   InvCipher

NAME

    InvCipher  -  Decrypts  a  block  of  ciphertext  using  the  Extended  AES
                  encryption algorithm.

Synopsis

    #include "eaes.h"

    void InvCipher(unsigned char *in, unsigned char *out);

DESCRIPTION

    Decrypts  the  ciphertext  entry  pointed  by  "in"  using the Extended AES
    ecryption  algorithm,  placing  the  resulting  data in the memory location
    pointed to by "out". Both "in" and "out" buffers must be 128-bits long
    (16 bytes).

    The  decryption  key  must have been previously defined via the call to the
    function KeyExpansion(). If the provided key is 128-bit, 192-bit or 256-bit
    long,  then the result is compliant with the AES specification as described
    in FIPS-197.

NOTES

    To  use  the  Extended EAES algorithm, you must include at your source code
    the following files:

        aestypes.cpp
        multresult.c
        eaes.cpp
        aestypes.h
        eaes.h
