- * This code implements the MD5 message-digest algorithm.

- * 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 MHD_MD5Init, call MHD_MD5Update as
- * needed on buffers full of bytes, and then call MHD_MD5Final, which
- * will fill a supplied 16-byte array with the digest.
