This is keyprint: a quick hack for printing S/Key keys on a small piece of paper, twice the size of a credit card for easy storage in a wallet, card holder, etc. It produces a PostScript file which can be printed and then trimmed to size: hn38925 +----------------------------------------+ | 1 af fd alfal 26 fd s fdas da | | 2 af fd alfal 27 fd s fdas da | | 3 af fd alfal 28 fd s fdas da | | . . | | . . | | 74 af fd alfal 98 fd s fdas da | | 75 af fd alfal 99 fd s fdas da | +----------------------------------------+ Warning: If you don't have a secure network, then it is not a good idea to print this key set on a network printer. It might be obvious, but you never know.

Gpasman is a password manager. People working with the internet have to remember lots of passwords. Saving them in a textfile is not a secure idea. Gpasman is a GTK solution to this problem since it saves the password information encrypted, so now you have to remember only one password instead of ten (or more). http://gpasman.sourceforge.net/

Knocker is a simple and easy to use TCP (no UDP yet) security port scanner which is able to analyze hosts and all of the different services started on them. (GTK+ version)

ClamSMTP is an SMTP filter that allows you to check for viruses using the ClamAV anti-virus software. It accepts SMTP connections and forwards the SMTP commands and responses to another SMTP server. The 'DATA' email body is intercepted and scanned before forwarding. ClamSMTP aims to be lightweight, reliable, and simple rather than have a myriad of options. It's written in C without major dependencies. If you need more options then you could use something big like AMaViS which is written in PERL and can do almost anything.

Google's Certificate Transparency project is an open framework for monitoring and auditing SSL certificates in nearly real time. It makes it possible to detect SSL certificates that have been mistakenly issued by a certificate authority or maliciously acquired from an otherwise unimpeachable certificate authority. It also makes it possible to identify certificate authorities that have gone rogue and are maliciously issuing certificates.

This program can convert your Checkpoint FW1 rulesets into XML files which can then be processed by Firewall Builder.

httprint is a web server fingerprinting tool. It relies on web server characteristics to accurately identify web servers, despite the fact that they may have been obfuscated by changing the server banner strings, or by plug-ins such as mod_security or servermask. httprint can also be used to detect web enabled devices which do not have a server banner string, such as wireless access points, routers, switches, cable modems, etc. httprint uses text signature strings and it is very easy to add signatures to the signature database.

This is a port of aimsniff, which sniffs Aol Instant Messanger conversations. It can also be setup to collect statistics on instant messaging traffic and display useful information using mysql and Web AIM Sniff
