cpm (Console Password Manager) is a small console tool to manage passwords and other sensitive data and store them in a public-key encrypted file. It also allows you to configure the whole hierarchy yourself, so it's easily adoptable for many requirements. The encryption is handled through GnuPG, and the data inside is stored as XML.
CKS is an openPGP (RFC2440) compliant public key server. It is currently under development. It is written in C, and runs on Linux. It uses PostgreSQL for key storage, and supports the hkp protocol (it can interface with GnuPG and NAI PGP). The keyserver is mostly functional, and there is a link to a running copy on the homepage.
EverCrack is a cryptanalysis engine. The overall design goal is to systematically break down complex ciphers into their simplex components for cryptanalysis (by the kernel). The kernel consists of an algebraic design (comparison and reduction) for breaking uniliteral, monoalphabetic ciphers instantaneously. Currently, it can break a 4000-word cipher in milliseconds. EverCrack currently has multi-language support for the user interface and cracking encryption in other language dictionaries (English, German, French, Spanish, Italian, Swedish, Dutch, and Portuguese).
Figaro's Password Manager 2 (FPM2) is a GTK2 port of Figaro's Password Manager, originally developed by John Conneely. It allows you to securely store your passwords, which are encrypted with the AES-256 algorithm. It allows you to copy passwords or usernames to the clipboard or primary selection. If a password is for a Web site, FPM can keep track of the URLs of your login screens and can automatically launch your browser. You can also teach FPM to launch other applications. FPM can sort your passwords into categories. Finally, it has a password generator that can help you choose good passwords.
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.
KisKis (Keep It Secret! Keep It Safe!) is an easy-to-use password manager. It allows the user to manage passwords for many different purposes, including network or Internet accounts, credit-card pin-numbers, and password-secured files. The accounts can be grouped hierarchically within a tree structure. Each account can be described by multiple attributes (such as user name or URL), file attachments, and comments. The history of each password change can be tracked. All passwords are stored in a single XML file using OpenPGP messages.
The OpenCA Project is a collaborative effort to develop a robust, full-featured and Open Source out-of-the-box Certification Authority implementing the most used protocols with full-strength cryptography world-wide. OpenCA is based on many Open-Source Projects. Among the supported software is OpenLDAP, OpenSSL, Apache Project, Apache mod_ssl.
PeaZip is a cross-platform file archiver utility that provides a unified portable GUI for many open source technologies like 7-Zip, FreeArc, PAQ, UPX, etc. Creates 7Z, ARC, BZ2, GZ, *PAQ, PEA, QUAD/BALZ, TAR, UPX, WIM, XZ, and ZIP files. It extracts more than 150 archive types: ACE, ARJ, CAB, DMG, ISO, LHA, RAR, UDF, ZIPX, and more. Features of PeaZip include extracting, creating, and converting multiple archives at once, creating self-extracting archives, split/join files, strong encryption with two factor authentication, an encrypted password manager, secure deletion, find duplicate files, calculate hashes, and export job definitions as scripts.
