John The Ripper MPI is an updated version of Ryan Lim's patch for John the Ripper to support MPI, in addition to a large number of third party patches to support additional ciphers and other features. MPI allows you to use multiple processors on a single system, or a cluster of systems for cracking passwords using John the Ripper.
A reasonable way to achieve a long term backup of OpenPGP (GnuPG, PGP, etc) keys is to print them out on paper. Due to metadata and redundancy, OpenPGP secret keys are significantly larger than just the "secret bits". In fact, the secret key contains a complete copy of the public key. Since the public key generally doesn't need to be backed up in this way (most people have many copies of it on various keyservers, Web pages, etc), only extracting the secret parts can be a real advantage. Paperkey extracts just those secret bytes and prints them. To reconstruct, you re-enter those bytes (whether by hand or via OCR), and paperkey can use them to transform your existing public key into a secret key.
FreeOTFE4PDA is an "on-the-fly" (OTFE) transparent disk encryption program. Using this software, you can create one or more "virtual memory cards" on your PDA. Anything written to one of these cards will be automatically and securely encrypted before being stored. A PC version is also available, allowing data encrypted on your PC to be read/written on your PDA, and vice-versa.
FlexiCA is a certification authority tool. It is implemented using Java and the Eclipse Rich Client Platform. FlexiCA is extensible and supports RSA, DSA, and Elliptic Curve cryptography out of the box. Other crypto-systems may be added easily, if ASN.1 structures for encoding are available. All cryptographic functions are provided by FlexiProvider.
SILC Crypto Toolkit (SCT) is a high performance multipurpose cryptographic toolkit for application programmers. It provides ciphers, hash functions, public key cryptosystems, MAC algorithms, multi-precision integers, cryptographic accelerators, an ASN.1 encoder and decoder, and many other features.
mnkPasswordKeeper is a simple password manager. The goal of this project is to permit the saving of passwords/notes on a USB key and be able to use the software on many platforms. It uses the Qt framework for GUI and XML reading. It uses Camellia from NTT as cipher. It has been run successfully on MS Windows, GNU/Linux, and Mac OS X.
Proto Balance SSL negotiates an SSL connection and forwards the plain HTTP connection to your Web server. Certificate management like request generation, vendor certificate installation, and key generation are all done from an easy-to-use Web interface. It load balances connections over multiple Web servers. It performs 1000 SSL transaction per second. Traffic management and on-the-fly redirection of traffic. On-the-fly adding and removal of servers. Traffic accounting and client-connection-rate limits. Denial of server protection. Layer 7 inspection and X-Forwarded-For support.
