The Open Protocol for Access Control Identification and Ticketing with privacY, is a standard suite of Key Establishment and Authentication protocols based on ECC and AES, for optimized contactless transactions and simple PKI based Key management.
The project Jaulp is jet another utility library project written in Java. It contains utility classes for Date ,Calendar, Collections, Resources, Files, IO for Random data, and many more. This is the last version for this project.
Blocked based Multi Identity Cryptographic Storage (BMICS) is a storage method that stores encrypted data of multiple users within a BMICS file without giving away details of the users in an explicit manner unless decrypted with the correct key.
NimpSmartCard is a framework to interact with smart cards through PC/SC readers as well as test/production readers such as Micropross and Smartware. The framework comes with sample tasks and a sample terminal manager which supports scripts and logs
JCrypTool moved to GitHub! See https://groups.google.com/d/topic/jcryptool-developers/nauEXL6vsbk/discussion for more information and visit our new project home at https://github.com/jcryptool
This project aims at porting visual cryptography, which only works with transparent slides, to ordinary 80g/m^2 white paper. Please read the documentation before using the program.
ShredBitz is a free and simple file shredder tool that can wipe selected files from any hard disk drive. ShredBitz is written in the java programming language and uses a custom written algorithm for shredding.
ShredBitz is a very powerful tool.
A web-based system to assign a set of known persons anonymous ids, such that every person only receives one id. The ids cannot be mapped to the corresponding persons afterwards.
Kotak is just another cracking tool which is based on Java. It is used to crack various types of hash functions with various types of attacks. It's developed to be as simple as possible, so that anyone can use this tool easily.
Kryptographie is a student project to implement historic encryption methods. It has a linux style command line interface. This project will also include the notes for my talk I'll hold on cryptography in school. (in German).
Software solution for creation and verification of digitral signatures. Can replace tokens and smart cards with mobile phones. Components included are client and server. Can creates, verifiy and store content and signatures. Offers secure sharing.
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.
SeCURePass password manager. A flexible, secure password manager for use in many situations, applicable for storing personal information. Integration with Firefox is available via an included extension.
If you need to protect your confidential files in office or shared desktops, here is the robust command line and GUI utility to do password based encryption using AES. It can encrypt and decrypt a folder structure containing any number of files.
Cryptography Workshop is a small yet powerful tool for cryptography and cryptanalysis. It's focused more on classic cryptography. It is currently in alpha and under development.
Backup P2P is a peer to peer application doing automated and secured backups inside a community (Jabber, XMPP). Each user shares some available space on his disk with others, to be able in return to remotely backup some of his own data.
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.
sanesigner is a high level digital signature api component. it support generating and verifying digital signatures as well as encryption and decryption using public keys, and lots of other features in between.
This tool encrypts text using polyalphabetic codetables, like the encryption systems in the middle ages. It can be used for simple text encryption with a small password or as a One-Time-Pad with a random codetable for 100% secure text encryption.
