| 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. |
