encryptanddecrypt.zip1k13-11-11File is not ratedEncrypt and Decrypt
These two files, encrypt and decrypt, will convert a string (any length) and a secret key into a list of numbers. The only way to decrypt is to use the decrypt function to convert back to a string. See readme for more info/instructions.
rsaencrypt.zip6k11-11-10File is not ratedRSA Encryption, Decryption, and Key Generation
Functions that can encrypt and decrypt messages in string format using the RSA encryption method. Also can generate both public and private keys. Functions are coded to handle extremely large numbers (tested to 10 digit primes, meaning 20 digit numbers to 20 digit powers).
string_encrypter.zip1k08-08-11File is not ratedString Encrypter
A simple program that encrypts and decrypts strings with a password. For a long description, look at the Read Me.
rotate13.zip1k07-04-26File is not ratedROTATE13 Tool
The ROTATE13 Tool will take a string from user input and apply ROT13 to it. Upper-case and lower-case letters are moved forward 13 places; for example, A would become N, and U would become H, and vice versa. ROTATE13 is symmetrical; re-applying ROT13 on an encoded string would return the original string. Needless to say, ROT13 has no effect on non-alphabetic characters. For more info on ROT13, such as its history, technical details, and applications, see: http://en.wikipedia.org/wiki/ROT13 ***This release is a direct port of the original TI-83+/84+ edition***
encwrap.zip1k05-04-18File is not ratedEncryption and Word Wrapper
This encryption program is completely invulnerable to Caesarian cryptanalysis, and is invulnerable to frequency analysis. It uses a key of random modifiers to alter the ASCII values of the text one character at a time. Al characters are supported, so you can use any symbol you want. The plaintext string or stringvar entered will be erased when finished, so you have to remember not to delete the key. Duh. The ciphertext and key list are both locked after they are created.
code.zip206k05-03-09File is not ratedCode
Code is, as the name implies, a code program. A very hard code, in my opinion, since you have to use ASCII to get the Hexidecimal digits of the squares of the Hexidecimal ASCII code of the digits of the code of the original string...I think...lol, even I'm not sure how to do it. THAT says something
coder.zip1k05-03-09File is not ratedCoder v1
Codes and decodes a string based on a password.
codexor.zip1k04-07-15File is not ratedThe XOR Cipher
This program is one of the best text encryption utilities available. It uses a random seed, random numbers, an encryption string that is not the same as ASCII, and the 'xor' command to turn text into gibberish. It can also turn it back.
pictenc.zip10k04-03-28File is not ratedPictoral Encryption/Decryption v1.5
This is an updated and fully functional version of its beta. The encrypting program takes text and returns a picture (really binary data). Details about the method of encryption are included in the readme. The decrypting program reverses the process. These programs were designed from a concept of applying complex computer-style algorithms to the TI-89. The programs work much faster when run on a computer implementing an emulator (reference to the hardware section of ticalc.org), but may be used on the calculator when you have the extra time. Note: these programs are large (around 18k each on the calc), so be prepared to make some space. Please read the readme file for instructions on how to quickly move the programs to archival memory.
ed.zip1k04-03-08File is not ratedSimple Decryption/Encryption

loss.zip1k03-12-09File is not ratedLoss V1.00
Loss provides lossy-encryption of strings. Lossy-encryption is designed to be both one-way and unbreakable. See the documentation for information about the encryption method. (C) 2003 Enchanted Coders.

encryption.zip1k03-03-07File is not ratedEncrypt
This program encodes/decodes a string of characters if provided with the right key, which you provide when encoding.
unbrkabl.zip1k03-03-07File is not ratedUnbreakable v1.0
String Encryptor/Decryptor written in BASIC. It will turn a string into a series of numbers! Great for password programs or just passing messages. Just tell it the variable name, and whether you want C-Spec on or off. C-Spec is a great feature that allows the string only to be decoded on the calculator it was encoded on. That way, if someone copies your strings they can't decode them (unless they steal your calculator). This is a great program that is easy to use! Please be sure to download it! Also, I like feedback, If you like it, let me know. If there are things you would like added to it, or changed on it, let me know!
