    VeraCrypt

    VeraCrypt

    Open source disk encryption with strong security for the Paranoid

    VeraCrypt is a free disk encryption software brought to you by IDRIX (https://www.idrix.fr) and based on TrueCrypt 7.1a. It adds enhanced security to the algorithms used for system and partitions encryption making it immune to new developments in brute-force attacks. It also solves many vulnerabilities and security issues found in TrueCrypt. This enhanced security adds some delay ONLY to the opening of encrypted partitions without any performance impact to the application use phase. This is acceptable to the legitimate owner but it makes it much harder for an attacker to gain access to the encrypted data. All released files are PGP signed with key ID=0x680D16DE, available on key servers and downloadable at https://www.idrix.fr/VeraCrypt/VeraCrypt_PGP_public_key.asc VeraCrypt can mount TrueCrypt volumes. It also can convert them to VeraCrypt format. Documentation: https://www.veracrypt.fr/en/Documentation.html FAQ : https://www.veracrypt.fr/en/FAQ.html

    A pronounceable password generator plugin for KeePass. NOTE: This project has been discontinued. It hasn't been worth it to maintain the project for a while now, so no more updates will be made to the plugin. The algorithm this plugin uses is based off FIPS-181 which was withdrawn by NIST a while back. The proliferation of password managers that seamlessly run on multiple platforms (some of which are free) has also removed almost all advantages of using randomly generated pronounceable passwords. If you have a use case for this plugin, reconsider it. If you still think using randomly generated pronounceable passwords are worth it for your use case, reconsider it some more.

    Cracx

    Cracx

    simple and light-weight archive password cracker

    Cracx allows you to crack archive passwords of any encryption using 7-zip, WinRAR or a custom command, via Brute Force or Dictionary attack. Note: You must NOT use this program with files you don't have the rights to extract/open/use them! Currently, the program requires a current version of either 7-zip or WinRAR to be installed, but you can also use it to bruteforce basically anything that is executably via command-line with custom parameters. On an i7 CPU, it runs approximately 30 combination tests per second. Feel free to make suggestions or contribute by implementing features and translating the tool into your native language!

    CSVHashCrack Suite

    CSVHashCrack Suite

    Multi hash crack suite

    This script is capable of cracking multiple hashes from a CSV-file like e.g. dumps from sqlmap. Over 17.000 md5-hashes in a CSV-file get cracked with a 14.300.000 lines wordlist in less then 1 min. Lines wich cant get cracked with the wordlist get stored in a .leftToCrack-File to further process with another Wordlist or the bruteforce-tool. In addition to the wordlist-cracker I created also a bruteforce-tool named CSVHashBrutforcer.

    AESTextCrypt

    AESTextCrypt

    Encrypt and decrypt text using AES 256 bit encryption

    AESTextCrypt is an easy-to-use open source tool for text encryption and decryption. Primarily intended for use with email, use it wherever you need to protect text from prying eyes. The encrypted text can be copy/pasted into any text-handling application (e.g. email) instead of plain text. Convenience buttons are provided for clipboard operations. AESTextCrypt uses AES-256 bit encryption which is the strongest available encryption scheme. It also employs bcrypt, which implements key-stretching and an adaptive key setup phase, the complexity (number of rounds) of which is automatically set to match the processing power of the encrypting computer. This makes it highly resistant to dictionary attack. AESTextCrypt is written in Java, so can be run on all desktop platforms - Windows, Mac and Linux.

    Vigenere Dictionary Attack

    Vigenere brute force / dictionary cracking tool

    This is a tool that uses a combination between a brute force and dictionary attack on a Vigenere cipher. At present, keys are generated using brute force (will soon try passwords generated from a dictionary first). Each key is then used to decode the encoded message input. The output is analysed and then put into a ranking table. Outputs will be ranked on a variety of factors (at present, only number of dictionary words in output are counted). For the future: Better key generation, trying combinations of dictionary words with numbers. If that fails, brute force will be used. For all attempts of the dictionary attack, only keys within the known key length range will be generated. Better ranking system and analysis of possible decoded messages. Note: The version currently released, I made in an evening! It is nowhere near ready for release but is a fun project to think about and I need more ideas for improvements mentioned above. Discuss possible solutions and ideas!

    Data Encrypton Software utilizing IMPACT

    We developed a classic solution that reflects the very nature of quantum mechanics in whole, ultimately demonstrating the raw power of numbers. We developed a truly irreversible one way algorithm which, when applied to information, both encrypts and decrypts it. That is to say that the algorithm which encrypts the information works in the same direction as the algorithm that decrypts it. This in itself is the very nature of quantum mechanics - "forward only". Through a quantum-entanglement-like operation, we created very robust encryption methodology which will secure information for some time to come through sheer numbers and flexibility. With 2^65536 possible keys a brute force attack on a key is simply infeasible. The full version, due to release March 11, 2013 will allow password protection which helps protect your information by forcing the impostor to not only produce the 65536 bit key, but have your password as well and allows for individual passwords for individual files.
