Camram is a hybrid antispam system combining multiple techniques improving the users e-mail experience.

Guncat has moved to GitHub, and can now be reached at https://fbb-git.github.io/guncat/ Please refer to github's location for the latest archive and releases.

StrongKey CryptoEngine (SKCE) 2.0 is a "crypto Swiss Army knife" server to perform cryptographic functions through web services, while freeing application developers to focus on business functionality. Its modules include: - A FIDO Engine to support FIDO U2F key registrations/authentications - An encryption engine to encrypt/decrypt files using AES/TDES keys - Escrowing keys to on-premises key management system (StrongAuth KeyAppliance/SAKA) - Integration to cloud storage services (AWS S3, Azure and Eucalyptus Walrus) - A signing engine to digitally sign documents, code, etc. with FIPS 140-2 HSM support - An LDAP Engine for AD/LDAP integration for authorization decisions SKCE is battle-tested and in production at one of the largest e-commerce companies in the world, protecting more than 50M documents within the business process; see http://bit.ly/14VPYlO for the case study. Download StrongKey CryptoCabinet (SKCC) on this site to see how to use SKCE.

This project is a C++ library which allows incorporating DKIM into an existing MTA or other application. It provides full support for signing, verifying, and SSP. It is compliant with RFC 4871.

Composed of a Java steganographic library and GUI to use steganography. Primarily intended for research communities on security and steganography to implement new dissimulation and steganalysis algorithms. More information at www.hidereveal.org

OpenSignature is an open source project for the digital signature of documents. It works with all cards supported by OpenSC and focuses on adding support for cards from accredited Italian CAs. The goal of the project is to provide a first single product

Generate RSA key pairs of arbitrary length; convert text between formats or use keys to transform/crypt text. Supports decimal, hexadecimal, base64 and text input and output. Entirely ANSI C++; no external dependencies.

Active dictionary attack on WEP keys in WLAN networks.

Web AND Mobile (Apple iPhone) based, multi user, java port of the KeePass project. A free, easy to use password manager which helps you to manage your passwords in a secure way. Focused on deep encryption and ease of use.

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.

Figaro's Password Manager (FPM) is a GNOME application that allows you to securely store & categorize your passwords, which are encrypted using the blowfish algorithm. It can launch applications using the host names, user names, and passwords you supply.

The Hopefully Uncomprehensible Shell, HUSH, is a secure shell client and programming library written in and for Java.

UnderMP3Cover is a mp3 steganography tool. It will allow you to write and read hidden messages within mp3 files without creating any audible differences to the mp3. The messages could be a text file, jpg or any other file depending on the mp3's size.

This tool can create XAdES (XML) signatures based upon ETSI TS 101 903 v1.3.2 standard. It also includes handling of ITU-T X.509 certificates and RFC 3161 timestamps.

haveged is a daemon that feeds entropy into the linux /dev/random pool using a random number generator based upon the HArdware Volatile Entropy Gathering and Expansion algorithm.

GPG is a Perl5 interface to gnupg (see http://www.gnupg.org). You can use standard scalar to communicate with gnupg. IPC is managed by IPC::Open3.

EntourageGPG provides powerful email encryption to Microsoft Entourage, using GPG as a backend.

A console-based tool for Linux that will provide simple functionalities to help decipher substitution ciphers.

Extend the functionality of the mount and the umount commands by adding support for basic device mapper devices, for key files and scripts and for filesystem checking at mount time while retaining support for loop device encryption.

This is a library for easy accessing chip cards /smart cards via a chipcard reader. It currently works under Linux, FreeBSD and Windows. It is tested with Towitoko and Kobil readers.

This is a set of programs convert a .p7m file into an .eml file. A private key of RSA would be needed when you convert an encrypted .p7m file.

Encrypt or decrypt 12, 15, 18, 21 or 24 BIP39 codewords array (so-called "seed phrase") using exclusive OR (XOR)/Vernam cipher (a.k.a. One Time Pad). If not input by a user, an encryption key is automatically generated at random. Encryption with such a key preserves integrity of BIP-39 checksums of all keys (that's distinct while also compatible with SeedXOR implementation).

CaesarCipher is a simple tool which helps you de/encrypt texts with the caesar cipher. This tool should not be used to encrypt sensitive data like passwords or personal information.

Clipperz is a web based password manager. Local encryption within the browser guarantees that no one except you can read your data. A true zero-knowledge (or host-proof) web app!

IKECrack is an IKE/IPSec crack tool designed to perform Pre-Shared-Key [password] analysis of RFC compliant aggressive mode authentication.
