Conversion tool that will convert a standard RSA key in OpenSSL PEM format into a PVK file and vice versa.

Fail2ban scans log files like /var/log/pwdfail or /var/log/apache/error_log and bans IP that makes too many password failures. It updates firewall rules to reject the IP address.

fchksum is a Python module to find the checksum of files. Currently it supports crc32 and md5 checksums. The advantage of using fchksum over the python md5 and zlib(.crc32) modules is both ease of use and speed. You only need to tell it the filename and the actual work is done by C code. Compared to the implementing a read loop in python with the standard python modules, fchksum is approximatly 2.0x faster in md5 and 1.1x faster in crc32.

These tools are used to test a PC/SC driver, card or reader or send commands in a friendly environment (text or graphical user interface).

Replacement for htpasswd. This port will install htpasswd.py that can be found in trac contrib directory.

The gnupg module allows Python programs to make use of the functionality provided by the GNU Privacy Guard (abbreviated GPG or GnuPG). Using this module, Python programs can encrypt and decrypt data, digitally sign documents and verify digital signatures, manage (generate, list and delete) encryption keys, using proven Public Key Infrastructure (PKI) encryption technology based on OpenPGP.

This is a small command-line utility for encryption and decryption using the principle of one-time pads (OTPs). One or more data files given to pad are XORd with each other and with RNG output, resulting in two or more output files. The output files are indistinguishable from random noise, except that when the pad utility is used to XOR them together again, the original data files may be recovered.

This is RATS, a rough auditing tool for security, developed by Secure Software Solutions. It is a tool for scanning source code (C, C++, Perl, and Python) and flagging common security related programming errors such as buffer overflows and TOCTOU (Time Of Check, Time Of Use) race conditions. As its name implies, the tool performs only a rough analysis of source code. It will not find every error and will also find things that are not errors. Manual inspection of your code is still necessary, but greatly aided with this tool.

Ruby/Password comprises a set of useful methods for creating, verifying and manipulating passwords. It includes an interface to CrackLib, a library commonly used for checking password strength.

xspy is a utility for monitoring keypresses on remote X servers. It takes advantage of an oversight in X Windows (R5 & R6) to find out about keypresses even in "secure mode". It works by polling the keyboard, by default every hundredth of a second.
