ccrypt is a command-line tool for encrypting and decrypting files and streams. It provides strong encryption based on the Rijndael cipher, a version of which is also used in the Advanced Encryption Standard.

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.

xxHash is an extremely fast non-cryptographic hash algorithm, working at RAM speed limit. It is proposed in four flavors (XXH32, XXH64, XXH3_64bits and XXH3_128bits). The latest variant, XXH3, offers improved performance across the board, especially on small data. It successfully completes the SMHasher test suite which evaluates collision, dispersion and randomness qualities of hash functions. Code is highly portable, and hashes are identical across all platforms (little / big endian). Performance on large data is only one part of the picture. Hashing is also very useful in constructions like hash tables and bloom filters. In these use cases, it's frequent to hash a lot of small data (starting at a few bytes). Algorithm's performance can be very different for such scenarios, since parts of the algorithm, such as initialization or finalization, become fixed cost. The impact of branch misprediction also becomes much more present.

HT is a file editor/viewer/analyzer for executables. The goal is to combine the low-level functionality of a debugger and the usability of IDEs. We plan to implement all (hex-)editing features and support of the most important file formats.

pamtester is a tiny utility program to test the pluggable authentication modules (PAM) facility, specifically designed to help PAM module authors to intensively test their own modules.

What is DracOS GNU/Linux Remastered ? DracOS GNU/Linux Remastered ( https://github.com/dracos-linux ) is the Linux operating system from Indonesia , open source is built based on Debian live project under the protection of the GNU General Public License v3.0. This operating system is one variant of Linux distributions, which is used to perform security testing (penetration testing). Dracos linux in Arm by hundreds hydraulic pentest, forensics and reverse engineering. Use a GUI-based tools-tools the software using the CLI (command line interface) and GUI (graphical user interface) to perform its operations. Now Dracos currently already up to version 3.1.5 with the code name "KUNTILANAK WITH REMASTERED".

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

Run executable from command line, akagi32 [Key] [Param] or akagi64 [Key] [Param]. First parameter is a number of methods to use, second is an optional command (executable file name including full path) to run. The second parameter can be empty - in this case, the program will execute elevated cmd.exe from the system32 folder. Since 3.5.0 version all "fixed" methods are considered obsolete and removed altogether with all supporting code/units. If you still need them. This tool shows ONLY popular UAC bypass method used by malware, and re-implement some of them in a different way improving original concepts. There are different, not yet known to the general public, methods. This tool is not intended for AV tests and not tested to work in aggressive AV environment, if you still plan to use it with installed bloatware AV soft, use it at your own risk.

ArpON (ARP handler inspection) is a Host-based solution that make the ARP standardized protocol secure in order to avoid the Man In The Middle (MITM) attack through the ARP spoofing, ARP cache poisoning or ARP poison routing attack.

PHP Screw is a PHP script encryption tool. When you are developing a commercial package using PHP, the script can be distributed as encrypted up until just before execution, preserving your intellectual property.

BitVisor is a tiny hypervisor initially designed for mediating I/O access from a single guest OS. Its implementation is mature enough to run Windows and Linux, and can be used as a generic platform for various research and development projects.

SSLScan queries SSL services, such as HTTPS, in order to determine the ciphers that are supported. SSLScan is designed to be easy, lean and fast. The output includes prefered ciphers of the SSL service, the certificate and is in Text and XML formats.

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.

The Safe C Library provides bound checking memory and string functions per ISO/IEC TR24731. These functions are alternative functions to the existing standard C library that promote safer, more secure programming. The ISO/IEC Programming languages — C spec, C11, now includes the bounded APIs in Appendix K, "Bounds-checking interfaces". This latest upload supports building static library, a shared library and a linux kernel module.
