/**@defgroup su_md5 MD5 Digest
|
|
*
|
|
* The MD5 message digest algorithm is described in RFC 1321 by R. Rivest,
|
|
* 1992. The algorithm takes as input a octet string of arbitrary length
|
|
* and generates a 128-bit hash value, "message digest" from the message
|
|
* contents.
|
|
*
|
|
* While some message collisions (different messages with same MD5 digest)
|
|
* has been generated, using collisions in an actual attack is much harder
|
|
* and MD5 can be considered as cryptographically strong.
