This little utility dumps MSRPC endpoint information from Windows systems. Similar to the rpcdump program from Microsoft, but does not need a DCE stack and so runs on Unixes. dcetest can be very useful once inside a DMZ to fingerprint Windows machines on the network. dcetest operates over TCP port 135. (Think of it as rpcinfo -p against Windows)

The digest utility is a wrapper for the md5, sha1, sha256, sha384, sha512, rmd160, tiger and whirlpool message digest algorithms (also known as hashes, checksums or "fingerprints").

fprint_demo is a simple GTK+ application to demonstrate and test libfprint's capabilities. It can be used to enroll new finger prints as well as verify and delete existing data sets.

Fprintd is a D-Bus daemon that offers libfprint functionality over the D-Bus interprocess communication bus. By adding this daemon layer above libfprint, we solve various problems related to multiple applications simultaneously competing for fingerprint readers. While it is not very nice to think of a daemon being necessary in this scenario, fprintd will be launched by D-Bus through the activation mechanism. This means it is launched only when needed, and additionally it will shut itself down after a period of inactivity. (Text copied from link below.)

Fwipe is a secure file erasing program. fwipe0, which actually erases your files, is immune to filenames containing spaces, carriage returns, dashes, or any other special characters. You can use it in place of rm in cron jobs, together with "find ... -print0". The output of fwipe0 is specially designed to be parsed easily by machine, so it can be embedded in other applications which need secure file erasure.

The IPv6 toolkit is a portable IPv6 security assessment suite produced by Fernando Gont on behalf of the UK CPNI.

Keychain is a shell script which acts as a user-friendly front-end to ssh-agent(1), allowing you to have one long-running ssh-agent process per system rather than per login session. Please study the documentation on the keychain website carefully since incorrect usage of this script may have certain security implications.

KeyNote is a simple and flexible trust-management system designed to work well for a variety of large- and small- scale Internet-based applications. It provides a single, unified language for both local policies and credentials. KeyNote policies and credentials, called `assertions,' contain predicates that describe the trusted actions permitted by the holders of specific public keys. KeyNote assertions are essentially small, highly-structured programs. A signed assertion, which can be sent over an untrusted network, is also called a `credential assertion.' Credential assertions, which also serve the role of certificates, have the same syntax as policy assertions but are also signed by the principal delegating the trust. This is an example implementation of the KeyNote Trust-Management System as specified in IETF draft <draft-blaze-ietf-trustmgt-keynote-02.txt>.
