Encoder.jar utility enrypts any file (containing text like .txt, .rtf, .html, .htm, .msg, .xml, etc.) and generates an encoded file. This encoded file may then be transferred via email or other medium from the source machine and can be decoded back to original on the target machine. The target machine should have Decoder.jar in order to reproduce it back to the original form. Decoder.jar decrypts an encoded file and regenerates the original file. Use : java -jar Encoder.jar java -jar Decoder.jar

Java based API (library) and console utility for cross-platform file and directory encryption and archiving. Encrypts single files up to 9.2 EB length. Directories can be encrypted as sets of single files in a single action. Uses Twofish (CBC) and SHA-256. Security level is strong and benefits from the PWS3 (Password Safe) encrypted file format. The level can be lowered to 128-bit key-length (normally 256).

Fileprivacy is a small tool which easily encrypts and decrypts files with common algorithms like AES, Blowfish, Triple DES and RSA. You can either use passwords or keyfiles. Since Fileprivacy is coded in Java it should run on all popular operating systems. #######BETA 2####### Bugfix - Beta 1 stopped working if filename was too short or long - added .exe file ####### NOTE ####### This is an early beta implying there are some issues left. The Keygenerator stops working if you change the algorithm after setting the keylength. It has to be restarted for further use. Because there are no start scripts, yet, you have to start Fileprivacy from console by typing: java -jar Fileprivacy-1.0_<version>.jar ####### ALSO NOTE ####### The author of this software is not responsible for the safety of your data. There is no guarantee that one or more of the implemented algorithms cannot be compromised.

A Security tool that will help to verify the hash codes of files . Currently,Our Hash Code verifier tool supports the following Hash types: MD5,SHA,CRC32. More details about the tool can be found in the project homepage.

This applet allows digitally sign documents with standard CMS is developed in Java using free software (libraries bouncycasttle).

A collection of useful Java classes.

This package implements the FF1, FF3, and FFX algorithms and the A2 and A10 parameter sets for format-preserving encryption. The FF1 and FF3 methods for format-preserving encryption are implementations of NIST Special Publication 800-38G, Recommendation for Block Cipher Modes of Operation: Methods for Format-Preserving Encryption. The FFX algorithm and A2 and A10 parameter sets are implementations of "The FFX Mode of Operation for Format-Preserving Encryption," by Mihir Bellare, Phillip Rogaway, and Terence Spies. For more information see the README.txt and package-info.java files in the source.

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

FroZenLight connects simple line art and mathematics. The source of light can be positioned so that either symmetric reflection patterns or secret messages (Cryptography) are created. Example light patterns and math exercises for education are provided.

The GPGUI program is GUI wrapping GnuPG functionality provided by Bouncy Castle. The program allows you to encrypt/sign/decrypt text messages and files using asymmeric PGP keys. The program can read and manage GnuPG keys if GnuPG is installed. But the program also maintains its own secret and public key files and having GnuPG installed is optional.

Eng: Digital Signature with x.509 certificates and smartcards for PDFand PAdES format documents in Spanish for Windows OS (8 and 10). Esp: Firma Digital de documents electrónicos PDF en formato PAdES con certificados digitales X.509 y tokens criptográficos en español.

The Ganymed SSH-2 for Java library (implementing the SSH-2 protocol) allows you to connect to SSH servers from within your Java programs.

Ganzúa is a cryptanalysis tool for classical ciphers (mono and polyalphabetic) that lets the user define almost completely arbitrary cipher and plain alphabets, allowing for the proper cryptanalysis of cryptograms obtained from non-English texts.

We at GCD are here to bring you ease in decoding your friends CRYPTIC GeekCode .signature files -=). Also sometime in the future we plan to eventualy start an ENCODER to help you even more!

This java tools design to decrypt and obtain the MS Windows Admin password from encrypted password get from Amazon EC2. It can run as standalone application or embedded as Java applet in HTML.

GiANT is a graphical interface for computer algebra systems (OS X/UNIX/Win). Currently GiANT lets the user work with number fields via KASH, but we aim to develop it into a GUI Library to run on top of any CAS and expose any of its functions.

A very simple file encryption tool. Release 1 is a text editor that saves encrypted files. Release 1.1 will include the ability to convert any file, even binary, to a GEF (Gulosh Encrypted File). Release 2.0 brings the strong encryption into play.

HTMF is a Java Hard Token Management Framework used to manage the complete livecycle of an organizations Smartcards and/or USB dongles. It communicates with the tokens through a PKCS11 interface.

HTTPBrute is used to calculate HTTP Digest Access Authentication as per RFC 2617. The tool will be able to perform brute force attacks to retrieve a lost password for a given Authentication response. MD5 is the only hashing algorithm implemented.

HashserGUI is a GUI interface for Jacksum. It is intended to provide a graphical tool to create hashes for files within a directory, and check the hashes generated. It works with many hash functions, as md5, sha1, sha256, sha512, md4, crc, etc.

"HelloWorld goes mobile" is a decentralized social network for mobile phones running under Google Android. It is based on XML and different JAVA encryption technologies. The software-structure is based on the desktop-orientated project "HelloWorld".
