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.
Pam_p11 is a pluggable authentication module (PAM) package for using cryptographic tokens such as smart cards and USB crypto tokens for authentication. Pam_p11 is very simple, as it has no config file, no options other than the PKCS#11 module file, and does not know about certificate chains, certificate authorities, revocation lists, or OCSP. There is one module that uses the $HOME/.eid/authorized_certificates file (like the old pam_opensc did) and one module that uses the $HOME/.ssh/authorized_keys file (like ssh does).
OpenCT implements driver and middlerware for smart card readers. OpenCT drivers can be used via the ct-api interface, the ifdhandler interface, or its own interface/middleware. It implements drivers for several USB crypto tokens, USB smart card readers, serial smart card readers, and PCMCIA smart card readers.
Perso can handle different types of identity card numbers (e.g. German/Austrian ID-card and passport). It can check the numbers for correctness using the "7-3-1"-checksum algorithm. Also it can extract information from the numbers (e.g. birthday) or generate example numbers using custom values.
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 Shrew Soft VPN Client for Unix is a free IPsec Client for FreeBSD, NetBSD, and Linux based operating systems. It can be used to communicate with systems running ipsec-tools. The Unix client utilizes the IPsec kernel support included with the operating system, and comes with the complete Internet Key Exchange daemon and client front end application source code. A Windows version is also available.
Publimark is a command line tool to secretly embed text in an audio file (i.e. audio steganography). Like cryptography, it uses a pair of keys: the public one can be shared, whereas the private one must be kept secret. Anybody can send a steganographic message, but only the private key owner will be able to read it. Of course, marked audio files are still playable without any noticeable change.
