    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 The algorithm this plugin uses is based off FIPS-181 which was withdrawn by NIST a while back.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!

    SSL Diagnos

    SSL Diagnos

    SSL Strength Evaluation and Test Utility

    SSL Diagnos is used to test SSL strength; get information about SSL protocols (pct, ssl2, ssl3, tls, dtls) and cipher suites. It can also be used for testing and rating ciphers on SSL clients. It has also specific support for pop3s, sip, smtp and explicit ftps. Tests for heartbleed (including dtls). Furthermore a separate tool, SSLPressure, not using openssl can be used to check the whole spectrum of possible SSL protocols on a server. Can also be used for testing ssl for mssql-servers (was added since nessus did not support this) and contains mitm poc for stripping ssl from mssql-connections.

    CrackThis!

    CrackThis!

    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.
