|
* Reference:
|
|
*
|
|
* 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
|
|
* md5_context_s structure, pass it to md5_init, call md5_update as
|
|
* needed on buffers full of bytes, and then call md5_final, which
|
|
* will fill a supplied 16-byte array with the digest.
|
|
*
