OTP (One Time Pad) In case you have any questions, contact me at: crypto-munition@gmx.de When used correctly, the OTP is an information-theoretically secure and demonstrably non-breakable encryption. The encryption process is implemented as symmetrical file encryption based on XOR encryption. The integrated pseudo-random generator serves only to illustrate and check the functionality. The use of this generator for REAL OTPs is not recommended. For REAL OTPs, hardware-based key generators (e.g. thermal noise of a pn junction, transistor or diode), white noise (e.g. out of tune radio) or other stochastic decay processes should be used. If used correctly, it cannot be decrypted by any intelligence service.

siggen is a cool email signature generator for encrypted ansi c (confused), brainf*ck, ... signatures. Use it in combination with vi(m), emacs, mutt, pine, or what ever. (tested on Solaris, Linux and Windoze). Optimized only for geeks :-)

Keyring lets you securely store digital secret keys on your Palm handheld computer. This information might include computer account passwords, credit card or banking numbers, GnuPG passphrases, or OPIE pads. (Previously "GNU Keyring for PalmOS".)

The In-Browser File Encrypter is a simple web application that enables you to securely encrypt your files directly in your browser using the AES-256 encryption algorithm in CBC mode.

Ank Zipper provides you with a lightweight, Java-based application designed to provide security to your documents. Ank Zipper can compress both files and folders and create password-protected archives, in order to prevent unauthorized access to important files. Additionally, it can be used for extracting or simply browsing ZIP files.It includes AES(Advanced Encryption Standard) algorithm to encrypt/decrypt file(s). Ank Zipper is a cross-platform software that can be used on any platform that features Java compatibility (e.g. Mac OS X, Linux, Windows).

With this tool you can create and sign x509 certificates, certificate request, create self-signed certificates, RSA private and public keys with simple and intuitive GUI. This program is using OpenSSL.

This program can encrypt / decrypt strings with the Caesar's Cipher. It also can try to crack an encrypted string with brute force. (C) Daniel Steinhauer <pik-9@users.sourceforge.net>

Cryptography Tools is a project to develop demonstration tools on classic (currently Caesar and Playfair) & modern crypto-systems, including private & public key encryptions, digital signatures, cryptographic hashes and authenticated encryption.

Cygnus Editor is a basic text-editing program created entirly in Java. And it's most commonly used to view or edit text files (.txt). A text file is a file type typically identified by the .txt file name extension. In Cygnus Editor you can encrypt your text document, so nobody can see the content of your document. Also you can decrypt your document and edit it. Cygnus Editor uses AES-256 encryption. AES-256 is the most powerful encryption standard yet. AES-256 uses many applications, websites and networks to secure their data. And now you can secure your document with Cygnus Editor.

DCrypt is an encryption and decryption tool that combines in a smart way multiple algorithms. The combination of multiple strong algorithms makes it much more difficult for hackers to get the plain content of the encrypted file without the password.

DKIM for JavaMail is a small JAR that can be easily implemented in existing Java projects using JavaMail for sending DKIM signed emails.

Text encoder to ENIGMA cryptosystem

This is a simple password manager for java enabled mobile phones. It is supposed to work with all MIDP1 compatible devices. It has been around for a long time and no comatibility problems have been reported in the last few years. FreeSafe uses a TwoFish

HashSum is a .NET port from GNU's md5sum and sha1sum. It supports: hash algorithm selection between MD5 and SHA1 (more could be added later) and compatibility between HashSum and GNU's checksum file format

MD5-utils is a script for MD5 hash function manipulations. It can crypt one or more word(s) and try to crack one or more hash(es) using online servers.

Net.MD5 is a handy MD5 checker and generator. It can encode unlimited bytes of data into 32bit key, and auto compare against original key. A visual GUI will keep MD5 more friendlier. It was written in C# under .NET Framework 2.0

OpenSSL Digest frontend for Windows. This program can be used to create/verify MD2/MD4/MD5/SHA/SHA1/MDC2/RIPEMD160 checksums of your files. OpenSSL32 now supports file encryption/decryption using various encryption Ciphers, such as Blowfish, Idea, DES,

The goal of Operation Project X is to crack the 2048-bit RSA private encryption key Microsoft uses to sign Xbox media, by using distributed computing. This key could be used by Xbox owners to run homebrew code on their machines.
