Open Source C Libraries for Linux

*NOTE* Migrated to http://github.com/cracklib/cracklib Next generation version of libCrack password checking library. As of Oct 2008 (reflected in 2.8.15 code release), licensed under LGPL.

Open source DKIM library, MTA filter implementation and associated tools.

NOTE: the libseccomp project has moved to https://github.com/seccomp/libseccomp The libseccomp library provides an easy to use, platform independent, interface to the Linux Kernel's syscall filtering mechanism: seccomp. The libseccomp API is designed to abstract away the underlying BPF based syscall filter language and present a more conventional function-call based filtering interface that should be familiar to, and easily adopted by application developers.

BBSGen is an improved Blum-Blum-Shub pseudorandom number generator. It consists of a C library (libbbsgen) and command-line tool (bbsgen). BBSGen can be used in applications and command-line as secure, unpredictable and strong PRNG.

The subject of this project is development of the Intrusion Detection System (IDS) with Artificial Neural Network (ANN). This model will allow the implementation of a system capable to analyze and to identify possible intrusions, based on the method of an

Clam AntiVirus Client Library provides a simple API to the ClamAV daemon. ClamAVC does not require ClamAV to be installed. ClamAVC communicates with clamd using clamd's documented protocol using either TCP or a local Unix domain socket.

Dunst is a lightweight replacement for the notification daemons provided by most desktop environments. It’s very customizable, isn’t dependent on any toolkits, and therefore fits into those window manager-centric setups we all love to customize to perfection. Customize fonts, icons, timeouts, and more. Are you unhappy with the default shortcuts and colors? No worries, you can change these all with a simple configuration file tweak. Change the look or behavior of notifications matching a specified pattern. You could use this to change the color of message notifications from your favorite jabber buddies, or to prevent important work email notifications from disappearing until you manually dismiss them. Specify the monitor that notifications should display on, or have them appear on the monitor with keyboard or mouse focus. Catch an unread notification disappearing from the corner of your eye? Just tap a keyboard shortcut to replay the last notification.

The Kevux Firewall program is one of the oldest Featureless Linux Library (FLL) programs. This project now exists outside of the FLL as its own distinct project and repository.

LibHideIP is a library that on-the-fly (by preloading) prevents programs from knowing your IP address. This makes them unable to know and reveal your location, thus helping keep the user's privacy. There is NO NEED to rebuild your software, because LibHideIP is a pre-loadable library, meaning you just need to RUN the software with LibHideIP loaded. LibHideIP is also a development library. See the project homepage https://libhideip.sourceforge.io and the project Wiki in the menu above.

LibNetBlock is a library that on-the-fly (by preloading) prevents a program under its control to use the network, to help to keep the user's privacy, prevent data leakage and virus spreading. You can think of LibNetBlock as a simple layer-7 (L7) firewall that simply blocks the network access for the program it controls. There is NO NEED to rebuild your software, because LibNetBlock is a pre-loadable library, meaning you just need to RUN the software with LibNetBlock loaded. LibNetBlock is also a development library. See the project homepage https://libnetblock.sourceforge.io and the project Wiki in the menu above.

LibSecRm (LIBrary for SECure ReMoval) is a set of replacements for these standard C functions which cause data removing from files. The data is first securely wiped on-the-fly, to protect the user's privacy, then the original functions are called. There is NO NEED to rebuild your software, because LibSecRm is a pre-loadable library, meaning you just need to RUN the software with LibSecRm loaded. LibSecRm is also a development library. The following wiping methods are supported: Gutmann-like, random, Schneier, DoD. See the project homepage https://libsecrm.sourceforge.io and the project Wiki in the menu above. To wipe data that was left on the drive by using "normal" delete operations, you can take a look at WipeFreeSpace (https://wipefreespace.sourceforge.io), which wipes the space used by files marked as deleted (and other things, too).

The problems of the unsafe C string functions such as the infamous strcpy() and strcat() are well-known, causing buffer overflows and leading to multiple security vulnerabilities. The SSM library is a safe and reliable alternative the old C string library.

A kind of encryption named "simple stream encrypt". The length of plaintext segment or the length of key is not limited, but must greater than zero. The lengths of every plaintext segment in a process don't require equivalency.

Libkpass is a from-scratch C implementation of reading and writing KeePass 1.x format password databases. Please check github for future updates.

PHP ClamAV - ClamAV Interface for PHP5 Scripts PHP-ClamAV is a PHP5 extension that allows to incorporate virus scanning features on your PHP5 scripts. It uses the Clam AV API for virus scanning.
