DavUtils is a collection of easy to use WebDAV client tools. The built-in client-side encryption allows you to encrypt and decrypt files on the fly with AES. Currently two command line tools are available: dav is a multipurpose WebDAV client that can be used like the standard unix tools ls, mkdir and rm. The other tool is dav-sync that can synchronize local files with a WebDAV server. It is very flexible and configurable and has advanced data safety features to prevent data loss. The integrated client-side AES encryption makes it secure to use public clouds.

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 print to screen or save to disk depending on whether the -f filename argument was given. If the -p passphrase argument is given a specific table is generated and is repeatable each time the same passphrase is given. This program was written to supplement the Enigma Simulator by Dirk Rijmenants. http://users.telenet.be/d.rijmenants/en/enigmasim.htm Enigma message procedures: http://users.telenet.be/d.rijmenants/en/enigmaproc.htm

Scrambler splits your files into a disired number of chunks and puts them together in a different order. This makes the file unreadable. In order to read them again you must unscramble them. Possible Uses: 1. Protect your private files (e.g. pictures, text, source file etc.) 2. Protect your hosted file on your website. (e.g. You can scramble the file and upload it. In order for the downloader to open the file he needs to unscramble the file. For this he will need the number of scrambles)

PGP Individual UID Signer makes signing all the UIDs on all of the keys at a PGP Keysigning party much simpler. It prompts for verification fingerprints, and then signs each UID on each key separately and PGP/Mime encrypt-emails them to their recipient. NOTE: Developement now happens at GitHub: http://github.com/jaymzh/pius

Libnsa stands literally for "Library: Non Semper erit Aestas". It is a small C++ library which implements RSA encryption. The current version only creates the 4096 bit public and private keys.

Hash mode interface to the Keccak code package. This program illustrates the use of the Keccak permutation. Usage is much more than a hash function. The NIST compatible settings are subject to change when they publish FIPS PUB 180-5. I wrote this program when evaluating the permutation and developing tree hashing for the Intel(R) MIC architecture.
