27
28
1. The functions md5_init, md5_append, and md5_finish have been moved into the 'mongo'
29
namespace and given C++ linkage, so that static archives of this library may be combined
30
with other libraries that expose functions of the same name.

Independent implementation of MD5 (RFC 1321).
36
37
This code implements the MD5 Algorithm defined in RFC 1321, whose
38
text is available at
39
http://www.ietf.org/rfc/rfc1321.txt
40
The code is derived from the text of the RFC, including the test suite
41
(section A.5) but excluding the rest of Appendix A. It does not include
42
any code or documentation that is identified in the RFC as being
43
copyrighted.

The original and principal author of md5.h is L. Peter Deutsch
46
<ghost@aladdin.com>. Other authors are noted in the change history
47
that follows (in reverse chronological order):
48
49
2002-04-13 lpd Removed support for non-ANSI compilers; removed
50
references to Ghostscript; clarified derivation from RFC 1321;
51
now handles byte order either statically or dynamically.
52
1999-11-04 lpd Edited comments slightly for automatic TOC extraction.
53
1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5);
54
added conditionalization for C++ compilation from Martin
55
Purschke <purschke@bnl.gov>.
56
1999-05-03 lpd Original version.
