     2  * This is the header file for the MD5 message-digest algorithm.

     3  * The algorithm is due to Ron Rivest.  This code was

     4  * written by Colin Plumb in 1993, no copyright is claimed.

     5  * This code is in the public domain; do with it what you wish.

     6  *

     7  * Equivalent code is available from RSA Data Security, Inc.

     8  * This code has been tested against that, and is equivalent,

     9  * except that you don't need to include two pages of legalese

    10  * with every copy.

    11  *

    12  * To compute the message digest of a chunk of bytes, declare an

    13  * MD5Context structure, pass it to MD5Init, call MD5Update as

    14  * needed on buffers full of bytes, and then call MD5Final, which

    15  * will fill a supplied 16-byte array with the digest.

    16  *

    17  * Changed so as no longer to depend on Colin Plumb's `usual.h'

    18  * header definitions; now uses stuff from dpkg's config.h

    19  *  - Ian Jackson <ian@chiark.greenend.org.uk>.

    20  * Still in the public domain.
