The wolfSSL embedded SSL library (formerly CyaSSL) is a lightweight, portable, C-language-based SSL/TLS library targeted at IoT, embedded, and RTOS environments primarily because of its size, speed, and feature set. It works seamlessly in desktop, enterprise, and cloud environments as well. wolfSSL supports industry standards up to the current TLS 1.2 and DTLS 1.2, is up to 20 times smaller than OpenSSL, offers a simple API, an OpenSSL compatibility layer, OCSP and CRL support, is backed by the robust wolfCrypt cryptography library, and much more. wolfSSL relies on the FIPS 140-2 validated wolfCrypt library for all cryptographic functionality. Visit http://wolfssl.com/wolfSSL/fips.html for more info!

yaSSL, or yet another SSL, is an embedded ssl library for programmers building security functionality into their applications and devices. yaSSL is highly portable, and runs on standard as well as embedded platforms(QNX, ThreadX, VxWorks, Tron) yaSSL is still available but no longer being developed. Current development on the same project continues under wolfSSL. Visit yaSSL Home above for the latest stable release.

[[We are in the progress of moving to github]] Metalinks is a project to facilitate data distribution over mirrors and P2P networks. It does so by defining an XML format and the tools to handle these. The metalink files contain all the information needed to download and verify files.

UFONet - Is a set of hacktivist tools that allow launching coordinated DDoS and DoS attacks and combine both in a single offensive. It also works as an encrypted DarkNET to publish and receive content by creating a global client/server network based on a direct-connect P2P architecture. + FAQ: https://ufonet.03c8.net/FAQ.html -------------------------------------------- -> UFONet-v2.0 [R3D] "R3DST4R!"

PyKCS11: a complete PKCS#11 wrapper for Python, created using the SWIG compiler. API documentation: http://pkcs11wrap.sourceforge.net/api/

AAD-50 is an open-source NVMe sanitization framework that closes a 15-year verification gap in Linux nvme-cli. The standard nvme sanitize command returns immediately after acceptance without confirming the drive actually completed the background erasure. AAD-50 fixes this by polling NVMe Log Page 0x81 (Sanitize Status) after every cycle and refusing to advance until SSTAT=0x1 confirms hardware completion. Implements a 50-cycle B→C→A phase matrix: 40 cycles NAND overwrite, 5 FTL block erase, 5 crypto key destruction. Generates a SHA-256 audit chain and PDF Certificate of Destruction aligned with NIST SP 800-88 Rev.2 Purge and IEEE 2883.1-2025. Runs on Linux CLI, Windows CLI, and Windows GUI. Supports USB enclosure passthrough via 3-tier SCSI/ATA pathway. Adopted into linux-nvme/nvme-cli master (PR #3438) in 14 days. Reviewed by Peter Gutmann (Gutmann 35-pass method) and Guido van Rossum (creator of Python). Confirmed by NVM Express Administration as recommended best practice.

Secret File is a free and easy to use encryption/decryption app that can encrypt nearly any kind of file format using passwords. Files can be stored as personal or sent over the internet as confidential as the data of files are securely encrypted at the binary level itself and can be decrypted at any time and anywhere. You can also use multi-level protection for more secureness.

An open source implementation of the FIDO2 protocol to support passwordless strong authentication using public-key cryptography. Supports registration, authentication (all platforms), and transaction authorization (for native Android apps).

Live Security/Forensics Linux Distribution, built from scratch and packed full of tools useful for vulnerability analysis, penetration tests, and forensic analysis.

Simple pygtk application for create and verify md5, crc32 and other checksum

Cia project tries to develop an all-purpose security tool. It's composed by ctools, the security tool; cfs, the app and cfs-server, a file & key server.

Colombiana is a tool used to recover, from given strings X and Y possible functions F : F(X) = Y. Very customisable, can recover a lot of functions.

CryptoPy is a pure python implmentation of cryptographic algorithms and applications. The algorithms are developed for readability more than speed. The collection now includes IEEE 802.11i specific algorithms that generated the test vectors for 802.11i.

Cryptography Tools is a project to develop demonstration tools on classic (currently Caesar and Playfair) & modern crypto-systems, including private & public key encryptions, digital signatures, cryptographic hashes and authenticated encryption.

DCrypt is an encryption and decryption tool that combines in a smart way multiple algorithms. The combination of multiple strong algorithms makes it much more difficult for hackers to get the plain content of the encrypted file without the password.

Development area for GNU/Linux 2.6.x for the KS8695 ARM SoC. Covers kernel patches, drivers for serial, Ethernet, PCI, GPIO, watchdog subsystems, and drivers for optional PCI based devices such as USB, WiFi, WiMAX, IPSec, SSL, and RSA devices.

Petoron Time Burn Cipher (PTBC) A promising cipher based on self-destruction of time, complete absence of traces and impossibility of key selection. Key features: AES-CFB encryption with per-file IV Argon2id key derivation with 256MB RAM resistance TTL (time to live) built directly into the encrypted file HMAC-SHA512 integrity verification Self-deleting mode (--autowipe) and one-time access marking (--onetime) No file metadata, no recovery, no password resets Philosophy: If you lose the password - it’s over. If time expires - it’s gone. PTBC doesn’t forgive, doesn’t forget, and doesn’t leak. https://github.com/01alekseev/PTBC

PassLock is a password manager and password generator that encrypts passwords using AES and saves them securely on your local machine. The password is encrypted and decrypted using a user-defined key and will get updated in each use. Extending the length of the private key will steadily improve the overall security. PassLock also generates a 40-bit long password consisting of lowercase, uppercase letters, numbers, and symbols Passlock's 220bit AES encryption and infinitely long password generator make your passwords nearly impossible to break and Its Console Based User Interface will definitely help to enhance your experience.
