Passfilter provides you with a terminal that has certain words blacklisted. Upon entering a predefined character sequence (defined as an MD5 sum), the terminal will erase the written characters with backspace, give an error message, and wait until the line is finished with the Enter key. The use case would be to stop you from accidentally entering passwords to IRC or possibly to other hosts, which could be compromised and could be logging your entry.
passwdqc is a password/passphrase strength checking and policy enforcement tool set, including an optional PAM module (pam_passwdqc), command-line programs (pwqcheck and pwqgen), and a library (libpasswdqc). On systems with PAM, pam_passwdqc is normally invoked on password changes by programs such as passwd(1). It is capable of checking password or passphrase strength, enforcing a policy, and offering randomly-generated passphrases, with all of these features being optional and easily (re-)configurable. pwqcheck and pwqgen are standalone password/passphrase strength checking and random passphrase generator programs, respectively, and are usable from scripts. libpasswdqc is the underlying library, which may also be used from third-party programs.
pdumpq can be used to take queued packets from netfilter/iptables and dump them to a file that decoders like tcpdump, ethereal, and snort can read. You can also just pipe it through to the packet decoder and see what is in those packets as they come in. This is also an easy way to populate your snort alert database with iptables data. Its features include automatic dumpfile rotation, filter on firewall marks and issue per-mark verdicts, and optional emailing of decoded packet dumps.
RFC 2015 defines a proposed Internet standard for sending PGP-encrypted email. This PGP/MIME has been incorporated into several MUAs such as Mutt and (with the AEGYPTEN project) KMail. However, a lot of email clients still don't support it. pgp-mime-handler can decrypt/verify such messages via a pipe, so it can be used as an email filter in many programs or scripts.
phpLogin is a user login and authentication module for the phpNova framework. It contains all user authentication-related tasks and UI. Dependencies include: phpSession, phpHash, and phpSQL. This module is part of the phpNova framework for PHP, which is currently in the alpha stages of development.
