|Up to TI-89 BASIC Misc. Programs
Codes and decodes a string based on a password.
|The 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.
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
|Word Combination Generator
This set, for the TI-83 -- V200 generates word combinations of whatever you input.
STRONGEST encryption program available
This is a algorithm for Encrypting/Decrypting strings, ideal for use in programs that need password protected encryption! It has a rate of approx .05 sec per char.
This is an advanced encryption engine. Very secure, Very small, and Very fast! A must download if u need to encrypt strings.
This is the most powerful Graphical encryption Program available. Period.
A cryptogram solver. Tell it what letters mean what, and it'll tell you what a given phrase is.
|Crypto 89 v1.0
An encryption/decryption program that uses xor and simple checksum.
An updated version to Crypt v1.0. This version does include encryption! It is impossible to figure out the password, and I challenge you to try!
This program takes a phrase, like Hi, and encrypts it to 072 105 and vice versa. See readme and screenshots for details.
This is a simple little (pointless) matrix based encryption utility. See the included readme file for how to use it. you may get a "singular matrix" error with some encryption matricies.
This programs a message in a complex code, and saves it on your calculator. The included decoder then decodes the message, exactly how you typed it!
|Text Encoder v1.0
Text Encoder for the TI-89
EncPro v1.1 is an efficient ecryption program currently supporting ROT13, RSA, and a Binary XOR. It provides user-friendly utilites to make your own keys and start encrypting now.
|Encrypt 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.
This program encodes/decodes a string of characters if provided with the right key, which you provide when encoding.
Encrypts and decrypts string data using a password
|Encryption 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.
It is a semi-good code that I made up for fun.
Enciphers a string into a code that is impossible (hopefully) to break.
Key3 is a simple string encryption/decryption function. What's new in this release: added support for using negative method numbers for encryption and positive method numbers for decryption. (C)2003, 2004 Enchanted Coders.
A function that returns the code of the key pressed on the HOME screen. Small, compact, easy to use.
crypting tool for Ti89,using a XOR.
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.
|Password Encryption v1.0
This program uses a password and a non periodic polyalphabetic encryption method to encrypt strings.
|Pictoral 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.
This program does the famous rot13 "code".
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***
This function lets you encrypt a string with the RSA algorithm. To break it, you have to factor a number with about 100 digits
|RSA 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).
RSA-Cryptor est un programme de codage tres efficace sur calculatrice utilisant l'algorithme RSA Version francaise English version for soon.
|RSA Encryption and Decryption Ti-89, Ti-92+ and Voyage 200
RSA is an Internet encryption and authentication system that uses an algorithm developed in 1977 by Ron Rivest, Adi Shamir, and Leonard Adleman.
program to generate keys and encode/decode function using the RSA algorithm
Encrypts what ever is on the graph screen and will also decrypt it. Usefull for sending messages to people.
|Shift String V1.00
Shift String is a weak string encryptor/decryptor based on shift ciphers. (C)2004 Enchanted Coders.
Uses the Solitaire Encryption Algorithm by Bruce Schneier ... also found in the book Cryptonomicon. It can encrypt and decrypt short messages.
|Spy Pics v1.0
SpyPics Version 1.0 This is an old app that i pulled outta the computer today This is the Program i wrote before CryptGUI. This one is very fast but not too powerful.. Yes, it does have Random Encryption as well as Regular passcode encryption. If you like to have little graphical encryption programs (especially ones that can make cool designs) then you need to Download this.
This is a cool encryption program I wrote that features four different encryption algorithms. One is impossible to break when used properly, the others were implemented for my math class and the rest for fun. Enjoy!
A simple program that encrypts and decrypts strings with a password. For a long description, look at the Read Me.
Will encrypt/decrypt strings using a password and the TI ASCII. No known bugs. Does long strings. Ideas to improve welcome.
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!
Converts a plaintext into a Vigenere cipher using any keyword you chose and can decrypt it.
