Kypeless
Fully decentralised secure p2p communication program
Kypeless encapsulates strong symmetric and asymmetric cryptography so you can get the benefits of secure communication following some simple steps. Right now, Kypeless is unstable pre-alpha software, published only for testing purposes. Kypeless allows you to exchange instant messages, long not-so-instant messages and files, but a lot more features are planned to be implemented later. -

MOTE CSPRNG & Stream Cipher
A family of small-state CSPRNGs and Stream Ciphers
MOTE is a fast, small-state, cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. MOTE exhibits uniform distribution, mixes extremely rapidly, has no detected bias, and comes in three variants: MOTE8, with an internal state array of 8+4 32-bit words; MOTE16, with an internal state of 16+4 words; and MOTE32 with a 32+4-word state. The former permit seeding with a key of up to 256 or 512 bits, the latter with a 1024-bit key. Reduced to essentials, MOTE is only... -

BEDBUG CSPRNG & Stream Cipher
A family of FLEA-inspired CSPRNGs and Stream Ciphers
BEDBUG is a small, fast, cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. It exhibits uniform distribution, mixes rapidly (with worst-case avalanche better than 16-bits), has no detected bias, and comes in three variants: BEDBUG128, with an internal state array of 128+3 32-bit words; BEDBUG256, with an internal state of 256+3 words; and BEDBUG512 with a 512+3-word state. The former permit seeding with a key of up to 4096 or 8192 bits, the latter with a... -

SES Super-Encypherment Scrambler
SES brings back the uncrackable onetime pad, with a digital twist.
SES brings back the uncrackable onetime pad, with a digital twist. It is well known that a random key of message-length is the only provably unbreakable cipher. SES uses cryptographic strength pseudo-random keys of message-length for its many encipherments, in addition to offering true one-time pad capability for the intrepid. SES is built on ISAAC, Bob Jenkins' unbroken CSPRNG, a fast and simple stream cipher placed in the Public Domain in 1996. SES now gives you the ability to... -

ISC - The ISAAC Stream Cipher
ISC lets you encrypt & decrypt text and files of any type up to 4GB
ISAAC is a cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. It was developed by Bob Jenkins from 1993-1996 and placed in the Public Domain. ISAAC is fast - especially when optimised - and portable to most architectures in nearly all programming and scripting languages. After more than 20 years of existence ISAAC has not been broken, and the little program you have here allows you to use it to encrypt and decrypt text of arbitrary length, files of any... -

xxteac - XXTEA Encrypter/Decrypter
xxteac - XXTEA Encrypter/Decrypter
This xxteac program utilizes the "Corrected Block TEA" encryption/decryption algorithm by Roger Needham and David Wheeler. The original algorithm has been slightly modified to allow arbitary length passwords / password files. -

Bigram Table Generator
A program to generate random reciprocal bigram tables
A command-line program to encrypt/decrypt a message using a random reciprocal bigram table and write a bigram table to a text file. Executing the program without any command-line arguments starts bigram in message encryption/decryption mode. The program prompts for a password or passphrase and a message to encrypt/ decrypt. After the message is entered the ciphertext is displayed. Executing the program with command-line arguments causes bigram to generate a random bigram table to... -

inKey
inKey - small & strong encryption utility (> 800 000 bit).
inKey - small encryption utility with big encryption block (> 800 000 bit). This program can protect very sensitive data, such e-mail, which has size up to 100 kilobytes, but processing speed might be too small with the bigger size of source data. ProcessingTime(data) = O(data ^ 2); USE IT ONLY TO PROTECT SMALL FILES (~ 100 Kb or a bit bigger). You can use "PaperBack" to print your 100 Kb encrypted *.iK file to A4 paper and get strong encrypted digital... -

MLCrypt
Simple, lightweight, standalone command-line single file encryption.
Simple, lightweight, cross-platform (Windows / Linux / ARM6 Linux), cross-arch (x32 / x64), standalone command line file encryption program. GnuPG is probably the best application for cross-platform encryption. However, its usage on Windows PCs may be inconvenient (installation administrator rights; large executable size for perhaps just a one-time file decryption, complicated command-line switches for stronger encryption). NCrypt would fulfill this task, but does not operate on 64-bit... -

Substitution Cipher Decryption
Decrypt messages encrypted with a substitution cipher
The provided program helps the user with the deciphering of a substitution cipher with the 26 letter alphabet by providing the following features • Dynamic entering of ciphertext. Ciphertext can be modified at any point of the process. • Easy location of corresponding characters in the ciphertext and the substituted text by selection. • Fast frequency analysis for single letters, bigrams, trigrams and quadgrams (more N -grams can be made available by adding a single line of code). •... -

Chaos Encrypter
Encrypter that use chaos system
This project contain two program: one is a text encrypter, this program can encrypt any file. Another is image encrypter, this program is designed to encrypt picture that can include alpha channel. You'd better use png format to save if you use image encrypter. Note: These programs are still experimental. If you want to use these programs, be care. -

FreeOTFE
A free "on-the-fly" transparent disk encryption program for PC & PDAs.
An upstream source site housing the original files for this mirror is no longer available. With this software, you can create one or more "virtual disks" on your PC/PDA. These disks operate exactly like a normal disk, with the exception that anything written to one of them is transparently, and securely, encrypted before being stored on your computer's hard drive. -
