* This code implements the MD4 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.
|

|
* Todd C. Miller modified the MD5 code to do MD4 based on RFC 1186.
|
||
|
|
*
|
||
|
|
* 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.
