PassGuard gpasman plugin
The PassGuard suite is a set of software that manages your passwords encrypted in a file. You just have to remember one, and different encrypted file formats are supported via plugins. The PassGuard gpasman plugin is the plugin that manages gpasman files encrypted with the RC2 algorithm.
PlexCrypt protects documents and folders via PKI-based encryption using secured algorithms such as AES, Blowfish, CAST, DES, ElGamal, IDEA, IES, RC4, RC6, RSA, Rijndael, Serpent Skipjack, Twofish, etc. It allows users to encrypt multiple files and folders automatically. PlexCrypt allows users to digital sign documents and folders and use that signature to verify that original document has not been maliciously or accidently altered. It supports MD5WithRSAEncryption, SHA1WithRSA/ISO9796-2, MD2WithRSAEncryption, RIPEMD160WithRSAEncryption, SHA1WithRSAEncryption, RIPEMD160WithRSAEncryption, MD5WithRSA/ISO9796-2, RIPEMD160WithRSA/ISO9796-2, RIPEMD160WithRSA/ISO9796-2 algorithms for digital signatures. PlexCrypt also allows users to archive a set of files and folders in the ZIP format and extract them later. In addition, it allows users to create and manage digital certificates and key-pairs for encryption and digital signatures.
RSA implementation in Octave
RSA implementation in Octave is a short, dirty, and very slow implementation of the cryptographic primitives of the RSA public key algorithm, using GNU Octave. It includes functions to work on big numbers, modular exponentiation, modular inversion, probabilistic prime numbers generators, key pair generators, and functions to encrypt and decrypt files using a rather insecure scheme.
CECrypt is a file encryption tool for Windows CE, that can encrypt with either 3-DES or IDEA.
guard bash is a shell wrapper that will execute an authentication phase before any command is executed. It uses a secret (user owned) algorithm method, and has a per user customizable procedure. If you need to connect to your computer from outside of your safe environment, even if you use SSH, you are vulnerable to simple attacks like key sniffing or to more complex attacks against SSH. If you have more than just one authentication method, you can more safely log in your account from an insecure Internet host.
mod_authenticache provides a simple and generic method for caching authentication information on the client side in order to enhance performance. It has been tested with several Basic HTTP authentication modules, and has an Apache 2.0.x optional function exporter for caching credentials from any custom authentication module.
imagesign is a utility to digitally sign images and store the signature within them in a comment block. This allows the images to be viewed as normal but their integrity can easily be verified with no extra information.
E-pad is a portable, commandline-driven encryption program. It is based upon the symmetric-key cryptosystem known as the one-time pad. It will encrypt or decrypt any file with any key regardless of filetype. It is designed with usability in mind, but it is also well-suited to work in batch files or shell scripts.
bcrypt is a blowfish file encryption utility which aims for cross-platform portability. In addition to providing 448-bit encryption, bcrypt overwrites input files with random garbage before deletion in order to make low-level data recovery much more difficult.
video-entropyd is a program to add entropy data from video4linux devices to the kernel random driver.
