The theta Encryption System is a TI-83-based encryption program. It has four main modes of operation: Standard Encrypt, which is a relatively secure triple-transposition cipher, Simple Shift, a replication of Caesar's Code providing basic security, List Encrypt, a one-for-one transposition cipher, and Cryptogrammer, a Cryptogram creator.

ASCIIEnc is a Macintosh conversion of the Theta Encryption System, with faster processing and increased security. This suite of programs allows you to encrypt with a 1 to 255-character passphrase, or a code block which can serve as a virtually unbreakable one-time pad. It also includes quick-encryption from the clipboard and direct-entry encryption in IRC.

ASCIIWeb is a new javascript-based implementation of the ASCIIEnc algorithm, with a few improvements over the AppleScript version! Now, you can pull ASCIIEnc up in your browser, and transfer text direct to your web-based email! Verison 1.0 Public release also includes multiple iterations for added security, support for linefeeds, and the ability to create fully-encrypted, password-protected webpages. ASCIIWeb also includes random code block and RLPassword generation.

NEW RELEASE 1.5 This program creates quick 'n dirty thumbnail galleries, which are mainly useful for on-disk image browsing and organization. The galleries are created by resizing the actual images into preview mode, so that they load immediately when clicked, but the broswer has to load all of the images for the preview page. It is recommended that IE be used in conjunction with this program, not because it's better (which it isn't), but because it caches pictures faster.

RLPassword is designed to create natural language passwords. These passwords are nonsensical words, and so cannot be guessed using a dictionary attack, yet at the same time are phonetically memorable so you won't forget them. Here's an example of eight-character passwords generated by the program: emicemaw, evowinaw, idelufah, upodiwit, utinegym, enumigev, abetapid, and orilodek. As you can see, none of them are actual words, but they are much easier to remember than something like axzvkbvo or gzxtm4n.

Cryptogrammer is a program designed to automatically create cryptogram puzzles, similar to the "Celebrity Cipher" column in most newspapers. A letter-for-letter transposition code, you can solve a cryptogram with a letter-frequency table and a knowledge of grammar and common words. Cryptogrammer generates the cryptograms, along with a full equivalency table for including hints (i.e. A equals E).

Steg is designed to be an assistant to ASCIIEnc, but can be used for other purposes. It is designed to mask sensitive data by hiding it within application files, by utilizing the data fork that is rarely used in Mac programs.
