Lawrie's Source Area

Its used to supply copies of a few things I've written, including:

The following are programs I use in my Cryptography course:

• AES Calculator - an applet used to encrypt or decrypt data values using the AES block cipher.
• DES Calculator - an applet used to encrypt or decrypt data values using the DES block cipher.
• IDEA Calculator - an applet used to encrypt or decrypt data values using the IDEA block cipher.
• XOR Calculator - an applet used to XOR two hex data values together and compute the hamming weight of the result.
• jkrypto - a program to create and analyse classical substitution and transposition ciphers.

  The following programs are used in my data communications and Cisco CCNA courses:

• DummyBrowser - a very simple minimalist web browser, written in Java, using the JEditPane swing component to render HTML pages, and to follow links to other pages.
• DummyDNS - a very minimal authorative, non-recursive, non-hierarchical DNS server, for use on small, isolated, test/lab networks.
• DummyServer - a simple TCP server program in Java, which can listen on one or more ports for client connections.

  And some other things I've written along the way:

• htbl.shar - a suite of simple perl scripts for managing a bibliography database kept using HTML like tags
• htol2ss - a perl script to convert files of HTML nested list lecture outlines to HTML slide-shows
• muck2html.tar.gz - a program for parsing a MUCK textual-VR database and turning into a set of HTML files
• vh - a shell script to start vi with a bunch of input mappings for HTML constructs
