Harbour MiniGUI Extended Edition. HARBOUR MINIGUI SOURCE WITH HMGS-IDE (IDE VISUAL TO MAKE WIN32 APLICATIONS WITH HARBOUR) UNNOFICIAL BUILD WITH EXTENDED NEW FEATURES.

Cross-platform high-level cryptographic library. Themis helps to build simple and complex cryptographic features easily, quickly, and securely. It’s a perfect fit for multi-platform apps. Themis hides cryptographic details and eliminates popular mistakes. Themis provides ready-made building blocks (“cryptosystems”) for secure data storage, message exchange, socket connections, and authentication. Secure Cell is a multi-mode cryptographic container suitable for storing anything from encrypted files to database records. Use Secure Cell to encrypt data at rest. Secure Cell is built around AES-256-GCM, and AES-256-CTR. Secure Message is a simple encrypted messaging solution for the widest scope of applications. Use Secure Message to send encrypted and signed data from one user to another, from client to server, to prevent MITM attacks and avoid single secret leakage. Based on ECC + ECDSA / RSA + PSS + PKCS#7.

Shadowsocks-libev is a lightweight secured SOCKS5 proxy for embedded devices and low-end boxes. Shadowsocks-libev is written in pure C and depends on libev. It's designed to be a lightweight implementation of shadowsocks protocol, in order to keep the resource usage as low as possible. Snap is the recommended way to install the latest binaries. You can build shadowsocks-libev and all its dependencies by script. The latest shadowsocks-libev has provided a redir mode. You can configure your Linux-based box or router to proxy all TCP traffic transparently, which is handy if you use an OpenWRT-powered router. Although shadowsocks-libev can handle thousands of concurrent connections nicely, we still recommend setting up your server's firewall rules to limit connections from each user. We strongly encourage you to install shadowsocks-libev from jessie-backports-sloppy.

This ASN.1 compiler turns ASN.1 specifications into C code. The asn1c is shipped together with conformant BER/DER/XER/PER codecs. The X.509, GSM TAP3, MEGACO, RRC and LDAP encoding and decoding examples are part of the source code distribution. NOTE: THE asn1c PROJECT HAS LARGELY MOVED TO GITHUB: http://github.com/vlm/asn1c

readpe (formerly known as pev) is a multiplatform toolkit to work with PE (Portable Executable) binaries. Its main goal is to provide feature-rich tools for properly analyze binaries with a strong focus on suspicious ones.

Keychain Framework is an Objective C Foundation-based framework for accessing Keychain and Security services under MacOS X. It provides convenience wrappers around the CDSA library included with MacOS X, facilities for manipulating keychains, and more.

An alternative to the string library for C and C++ which is more functional and does not have buffer overflow problems.

A package of Rijndael, Twofish and Serpent encryption algorithms implemented in x86 assembly. Meant to learn basics of assembly, learn about the algorithms or to be used in a C program.

The AWS Encryption SDK for C is a client-side encryption library designed to make it easy for everyone to encrypt and decrypt data using industry standards and best practices. It uses a data format compatible with the AWS Encryption SDKs in other languages. For more information on the AWS Encryption SDKs in all languages, see the Developer Guide. We will demonstrate some simple build recipes for Linux, Mac, and Windows operating systems. These recipes assume a newly installed system with default installs of dependency packages. The Windows instructions install everything in your current directory (where you run the build process). The AWS Encryption SDK for C can be used with AWS KMS, but it is not required. For best results when doing a build with AWS KMS integration, do not install aws-c-common directly. Build and install the AWS SDK for C++, which will build and install aws-c-common for you (see the C++ SDK dependencies here).

Portable, optimised implementation of Bruce Schneier's 64-bit symmetric block cipher, Blowfish. Includes support for ECB, CBC, CFB, OFB and CTR block cipher modes, weak key detection and parallelisation using OpenMP.

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.

A simple and incredibly powerful tool for scripting and fuzzing arbitrary network protocols written using the Chicken Scheme-to-C compiler.

The IEEE 1619 Committee open-source reference implementations of encryption algorithms, plus testing and certification suites, for each encryption algorithm included in the standard.

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 MOdelchecking Programs for Security(MOPS) project produces software you can use to find security bugs in your C programs. Examples include time to check to time of use bugs, abuses of setuid, and more.

MpNT is a multi-precision number theory library that provides a base for building cryptographic applications. It may however be used in any domain where efficient integer, modular, and floating-point computations involving large numbers are required.
