/*
* This code implements the MD5 message-digest algorithm.
* The algorithm is due to Ron Rivest. This code was
* written by Colin Plumb in 1993, no copyright is claimed.
* This code is in the public domain; do with it what you wish.
*
* Equivalent code is available from RSA Data Security, Inc.
* This code has been tested against that, and is equivalent,
* except that you don't need to include two pages of legalese
* with every copy.
*
* To compute the message digest of a chunk of bytes, declare an
* MD5Context structure, pass it to MD5Init, call MD5Update as
* needed on buffers full of bytes, and then call MD5Final, which
* will fill a supplied 16-byte array with the digest.
*/

/* Minor tweaks for use from Omega:
*
* + Include <cstdint> to get uint32_t.
* + uint32 -> uint32_t.
* + MD5Transform is an internal helper so prototype moved to md5.cc.
* + Removed MD5_CTX.
* + Changed MD5Context.in to uint32_t instead of unsigned char.
