5 | * This is the header file for the MD5 message-digest algorithm. |
6 | * The algorithm is due to Ron Rivest. This code was |
7 | * written by Colin Plumb in 1993, no copyright is claimed. |
8 | * This code is in the public domain; do with it what you wish. |
9 | * |
10 | * Equivalent code is available from RSA Data Security, Inc. |
11 | * This code has been tested against that, and is equivalent, |
12 | * except that you don't need to include two pages of legalese |
13 | * with every copy. |
14 | * |
15 | * To compute the message digest of a chunk of bytes, declare an |
16 | * MD5Context structure, pass it to MD5Init, call MD5Update as |
17 | * needed on buffers full of bytes, and then call MD5Final, which |
18 | * will fill a supplied 16-byte array with the digest. |
19 | * |
20 | * Changed so as no longer to depend on Colin Plumb's `usual.h' |
21 | * header definitions; now uses stuff from dpkg's config.h |
22 | * - Ian Jackson <ijackson@nyx.cs.du.edu>. |
23 | * Still in the public domain. |
24 | * |
25 | * Josh Coalson: made some changes to integrate with libFLAC. |
26 | * Still in the public domain, with no warranty. |
