BeeCrypt is an open source cryptography library that contains highly optimized C and assembler implementations of many well-known algorithms including Blowfish, MD5, SHA-1, Diffie-Hellman, and ElGamal. Unlike some other crypto libraries, BeeCrypt is not designed to solve one specific problem, like file encryption, but to be a general purpose toolkit which can be used in a variety of applications. The BeeCrypt library currently includes: - Entropy sources for initializing pseudo-random generators - Pseudo-random generators: FIPS-186, Mersenne Twister - Block ciphers: Blowfish - Hash functions: MD5, SHA-1, SHA-256 - Keyed hash functions: MD5/HMAC, SHA-1/HMAC, SHA-256/HMAC - Multi-precision integer library, with assembler-optimized routines - Probabilistic primality testing, with optimized small prime trial division - Discrete logarithm parameter generation over a prime field - Diffie-Hellman key agreement - DHAES encryption scheme - ElGamal signature scheme (two variants) - Basic RSA primitives and key pair generation

Crypt::xDBM_File encrypts/decrypts the data in a gdbm, ndbm, sdbm (and maybe even berkeleyDB, but I didn't test that) file. It gets tied to a hash and you just access the hash like normal. The crypt function can be any of the CPAN modules that use encrypt, decrypt, keysize, blocksize (so Crypt::IDEA, Crypt::DES, Crypt::Blowfish, ... should all work) ***IMPORTANT*** Encryption keys (the key you pass in on the tie line) will be padded or truncated to fit the keysize(). Data (the key/values of the hash) is padded to fill complete blocks of blocksize(). The padding is stripped before being returned to the user so you shouldn't need to worry about it (except truncated keys). Read the doc that comes with crypt function to get an idea of what these sizes are. If keysize or blocksize returns a zero the default is set to 8 bytes (64 bits).

This is an alpha release of a PGP module for Perl5.This module will allow for an easy interface to both Phil Zimmermann'sPGP (v2.6.2) program and the international version of PGP (v2.6.2i). PGP.pm will allow you to sign, encrypt (w/signature), decrypt and perform key management. The only requirement being that you alreadyhave PGP installed on your system to utilize this module.There are sure to be many changes in the structure of this module overthe next couple of months--at least until a standard interface is acheived. If you find this module useful and wish to see future developments of it, the contribute to Phil Zimmermann's legal defense fund. Ifyou don't know anything about the government's attempt to wrongfully prosecute Phil, then go to Yahoo and search for "Zimmermann." After reading for a little while, you will be wondering how the governmentis getting away with it's criminal act.

The Heartbeat program is one of the core components of the Linux-HA (High-Availability Linux) project. Heartbeat is highly portable, and runs on every known Linux platform, and also on FreeBSD and Solaris. Ports to other OSes are also in progress. Heartbeat is the first piece of software which was written for the Linux-HA project. It performs death-of-node detection, communications and cluster management in one process. The Heartbeat program has been around for a while. It has a great many strengths, and yet there were a few weaknesses in version 1 that needed to be addressed: - limitation on two nodes for cluster size - inability to monitor resources for their correct operation - minimal ability to express dependency information This release removes these limitations.

Scanmem is a simple interactive debugging utility for Linux, used to locate various data in an executing process. This can be used for the analysis or modification of a hostile process on a compromised machine, help in reverse engineering, or to cheat at video games. Brief list of its features: - Interactive command mode, with internal help - Efficient and easy-to-use syntax - Support for different data types: integers, floats, bytearrays, strings - Support for different scan (comparison) types: equal, greater/less than, changed, unchanged, increased/decreased - Set any variable to any value - Detailed information about mappings, allow users to eliminate regions More in GameConqueror, optional PyGTK-based GUI: - User-friendly CheatEngline-alike interface - Modify and lock (freeze) variables - Memory viewer/editor It requires linprocfs(5) to be mounted under /compat/linux/proc to operate.

gcombust is a GTK+ frontend for mkisofs and cdrecord. At this moment every release of gcombust isn't always very well tested; it would probably be wise to test it with the -dummy option at first to check that I haven't made any stupid errors. Also, it prints the command it's executing to stdout so you can look at it and maybe spot errors. I love to receive feedback/comments/ideas/bugreports at: jmunsin@iki.fi (jmunsin@abo.fi) NOTE: If you decide to do a NLS translation of gcombust, it might be a good idea to mail me about it to make sure no one else is doing one for the same language.

http://en.wikipedia.org/wiki/MogileFS: MogileFS was created by Danga Interactive for use with LiveJournal. It is similar to the Andrew File System in its design goal. It is different than a traditional filesystem in that the user has to access files via an API. However, it's possible to implement the file system in user space using FUSE, or a similar package. MogileFS enables horizontal scaling of storage across any number of machines. Files are replicated between machines according to customizable rules such that at any time a number of drives or machines could be lost without data becoming unavailable. It is designed for high volume applications, such as high traffic websites, to spread storage across cheaper machines without relying on technologies such as NFS.

Ever wished the compactness of shell scripts be put into a real programming language? Say hello to Plumbum Shell Combinators. Plumbum (Latin for lead, which was used to create pipes back in the day) is a small yet feature-rich library for shell script-like programs in Python. The motto of the library is ?Never write shell scripts again?, and thus it attempts to mimic the shell syntax (shell combinators) where it makes sense, while keeping it all Pythonic and cross-platform. Apart from shell-like syntax and handy shortcuts, the library provides local and remote command execution (over SSH), local and remote file-system paths, easy working-directory and environment manipulation, and a programmatic Command-Line Interface (CLI) application toolkit. Now let?s see some code!

This program will help you recover disks with bad sectors. You can recover files as well complete devices. In case if finds sectors which simply cannot be recoverd, it writes an empty sector to the outputfile and continues. If you're recovering a CD or a DVD and the program cannot read the sector in "normal mode", then the program will try to read the sector in "RAW mode" (without error-checking etc.). This toolkit also has a utility called 'mergebad': mergebad merges multiple images into one. This can be usefull when you have, for example, multiple CD's with the same data which are all damaged. In such case, you can then first use recoverdm to retrieve the data from the damaged CD's into image-files and then combine them into one image with mergebad.

Terminal mixer can start processes inside a pseudo-terminal, which can be accessed through a Unix socket, TCP or even raw ethernet (not yet ported to FreeBSD). The programs can be linked to the current terminal, or they can be unlinked like in nohup. But even in this latter case you can connect to them using the mentioned protocols. tm can also start programs as if they communicate through pipes instead of terminals, and this can be quite useful for remote-controlling applications. More than one client can connect to the served pseudo-terminal, either using tm as a client or telnet for TCP. You can choose if they are only allowed to read, or they can also contribute on input.
