# md5.tcl - MD5 in Tcl
|
||||
# Author: Don Libes <libes@nist.gov>, July 1999
|
||||
# Version 1.2.0
|
||||
#
|
||||
# MD5 defined by RFC 1321, "The MD5 Message-Digest Algorithm"
|
||||
# HMAC defined by RFC 2104, "Keyed-Hashing for Message Authentication"
|
||||
#
|
||||
# Most of the comments below come right out of RFC 1321; That's why
|
||||
# they have such peculiar numbers. In addition, I have retained
|
||||
# original syntax, bugs in documentation (yes, really), etc. from the
|
||||
# RFC. All remaining bugs are mine.
|
||||
#
|
||||
# HMAC implementation by D. J. Hagberg <dhagberg@millibits.com> and
|
||||
# is based on C code in RFC 2104.
|
||||
#
|
||||
# For more info, see: http://expect.nist.gov/md5pure
