The reasoning behind this, is that if we are consistent in our documentation about the uint*_t stuff, people will be less tempted to write new code that uses the non-standard types. I am not going to bump the man page dates, as these changes can be considered style nits. The meaning of the man pages is unaffected. MFC after: 1 month

.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
module implements the RSA Data Security, Inc.\& MD5 Message-Digest Algorithm
|
|
(MD5).
|
|
It produces 128-bit MD5 Digest of data.
|
|
.Bl -hang -width MD5Transformxxx
|
|
.It Pa MD5Init
|
|
must be called just before
|
|
.Fn MD5Transform
|
|
will be used to produce a digest.
|
|
The
|
|
.Fa buf
|
|
argument is the storage for the digest being produced on subsequent
|
|
calls to the
|
|
.Fn MD5Transform
|
|
routine.
|
|
.It Pa MD5Transform
|
|
is the core of the MD5 algorithm, this alters an existing MD5 hash
|
|
kept in
|
|
.Fa buf
|
|
to reflect the addition of 64 characters
|
|
of new data passed in
|
|
.Fa block
|
|
argument.

.Sh COPYRIGHTS
|
|
The code for MD5 transform was taken from Colin Plumb's
|
|
implementation, which has been placed in the public domain.
|
|
The MD5 cryptographic checksum was devised by Ronald Rivest, and is
|
|
documented in RFC 1321, "The MD5 Message Digest Algorithm".
