A JavaScript implementation of the Secure Hash Algorithm

Version 2.2 Copyright Anonymous Contributor, Paul Johnston 2000 - 2009.

See <http://pajhome.org.uk/crypt/md5> for details.

This package adds javascripts capable of performing md5 and
sha1 hashes, and makes them available at /jshash on the local
webserver.

To use them add the following block of code to your pages:

    <script type="text/javascript" src="/jshash/sha1.js"></script>

# Tcl package index file, version 1.1
# This file is generated by the "pkg_mkIndex" command
# and sourced either when an application starts up or
# by a "package unknown" script.  It invokes the
# "package ifneeded" command to set up package-related
# information so that packages will be loaded automatically
# in response to "package require" commands.  When this
# script is sourced, the variable $dir must contain the
# full path name of this file's directory.

package ifneeded httpd::jshash 0.1 [list source [file join $dir jshash.tcl]]
