|
* This is the header file for 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.
|
|
*
|
|
* Changed so as no longer to depend on Colin Plumb's `usual.h'
|
|
* header definitions; now uses stuff from dpkg's config.h
|
|
* - Ian Jackson <ijackson@nyx.cs.du.edu>.
|
|
* Still in the public domain.
|
|
*
|
|
* Josh Coalson: made some changes to integrate with libFLAC.
|
|
* Still in the public domain.
