It performs simple XOR operation on files from a given key or by generating data from a given short password.

xxHash is an extremely fast non-cryptographic hash algorithm, working at RAM speed limit. It is proposed in four flavors (XXH32, XXH64, XXH3_64bits and XXH3_128bits). The latest variant, XXH3, offers improved performance across the board, especially on small data. It successfully completes the SMHasher test suite which evaluates collision, dispersion and randomness qualities of hash functions. Code is highly portable, and hashes are identical across all platforms (little / big endian). Performance on large data is only one part of the picture. Hashing is also very useful in constructions like hash tables and bloom filters. In these use cases, it's frequent to hash a lot of small data (starting at a few bytes). Algorithm's performance can be very different for such scenarios, since parts of the algorithm, such as initialization or finalization, become fixed cost. The impact of branch misprediction also becomes much more present.

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.

yaSSL, or yet another SSL, is an embedded ssl library for programmers building security functionality into their applications and devices. yaSSL is highly portable, and runs on standard as well as embedded platforms(QNX, ThreadX, VxWorks, Tron) yaSSL is still available but no longer being developed. Current development on the same project continues under wolfSSL. Visit yaSSL Home above for the latest stable release.

Yavipind is a secure tunnel aka 2 peers securely forward­ing packets toward each other.It is what most people calls a VPN (virtual private network). It forwards any kind ofpacket (IPv4, IPv6 or other) sent over the virtual network interface (e.g. t

YAWCU is a wireless LAN (WLAN) capture + WEP cracking utility. It can crack 64/128 Bit WEP keys on IEEE 802.11b/g networks by monitoring WLAN traffic and computing the resulting WEP key once enough packets have been gathered

yubikey-agent is a seamless SSH agent specifically built for secure hardware tokens such as YubiKey (and other PIV tokens). It aims to replace the standard SSH agent with a version tailored for these security devices; the key is generated on the hardware token (so it can’t be extracted), every session requires a PIN and a physical touch, and the agent is resilient to unplugging, sleep/suspend, and restarts. Setup is simple, one command and one environment variable, and then the agent just runs in the background. Because it uses pure Go and leverages libraries like go-piv/piv-go and golang it works across platforms and integrates cleanly into SSH workflows. For developers or administrators who prioritize hardware-based SSH key security, this tool lowers the friction of using secure tokens in day-to-day SSH workflows. It also supports modern best practices in SSH authentication and brings stronger guarantees of key security in a user-friendly interface.

One of the project groups in Intake 6 is planning on doing a IM client which is secure. This includes messenging, file sending, picture drawing, video transmissions by far.

HcryptoJ (Historical cryptology in Java) is a Java based programming library for implementing and analyzing historical ciphers. HcryptoJ is designed to support research and teaching in historical cryptography and computer science. Licensed under GPL.

A smart card-based public key cryptography system based on elliptic curves, using AES for session key generation and SHA for hashing. This project will include the smart card software, terminal software, and a public key server.

A simple encrypter/decrypter written in C with a graphical user interface written in Python. This tool was written to help forums' users to have their credits for the files they uploaded by putting their usernames from each forum they are active. *This encypting software generates a symetric key based in the password. The lenght of the key is variable. The rule for the length is: (Num_Of_Chars_In_Passwrd)^2 bytes .

This is a free and open source java library to generate license for your application. Use this library to make your custom license file with your own extension. It encrypts the license file with the one time pads encryption technique to make it hard to break. The generated license file can be set to expire after certain time, and also can be set to expire manually after a certain action.
