GnuPG
Complete and free implementation of the OpenPGP standard
GnuPG (GNU Privacy Guard) is a widely used free software encryption system that implements the OpenPGP standard to provide secure communication and data protection across multiple platforms. It uses a hybrid cryptographic approach combining symmetric encryption for performance with public-key cryptography for secure key exchange and identity verification. The software allows users to encrypt files and messages, create digital signatures, and manage cryptographic keys, making it a foundational tool for privacy-focused workflows. Because it is open source and licensed under the GNU GPL, GnuPG can be freely audited, modified, and redistributed, which has contributed to its adoption in security-sensitive environments. ... -

Minisign
A dead simple tool to sign files and verify digital signatures
Minisign is a lightweight command-line utility designed for generating and verifying digital signatures with a strong focus on simplicity, security, and portability. It uses the modern Ed25519 public-key cryptographic system to produce fast and compact signatures, making it well-suited for software distribution and file integrity verification. The tool is intentionally minimalistic, performing a single task efficiently without unnecessary complexity, which makes it easy to integrate into... -

DSVPN
A dead simple VPN
DSVPN is a Dead Simple VPN, designed to address the most common use case for using a VPN. Runs on TCP. Works pretty much everywhere, including on public WiFi where only TCP/443 is open or reliable. Uses only modern cryptography, with formally verified implementations. Small and constant memory footprint. Doesn't perform any heap memory allocations. Small (~25 KB), with an equally small and readable code base. No external dependencies. Works out of the box. No lousy documentation to read. No configuration file. No post-configuration. Run a single-line command on the server, a similar one on the client and you're done. ... -
Run applications fast and securely in a fully managed environmentRun frontend and backend services, batch jobs, deploy websites and applications, and queue processing workloads without the need to manage infrastructure.

AWS Encryption SDK for C
AWS Encryption SDK for C
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... -

xxHash
Extremely fast non-cryptographic hash algorithm
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).... -

BoringSSL
Mirror of BoringSSL
BoringSSL is a Google-maintained fork of OpenSSL, designed specifically to meet the security, performance, and maintainability needs of Google’s infrastructure and products. While fully open source, BoringSSL is not intended for general public use — it serves as a streamlined, heavily modified SSL/TLS and cryptography library optimized for Google’s internal ecosystem, including Chrome/Chromium, Android, and other Google services. The project prioritizes security, simplicity, and maintainability over backward compatibility. Unlike OpenSSL, BoringSSL provides no guarantee of stable APIs or ABIs, meaning third-party projects depending on it may frequently break. ... -

denuvo
DENUVO (VMProtect 2.6x) VM research tool
This is part of the original source code of DENUVO_Profiler, written by 386 Team in 2014-2017 to investigate the first versions of DENUVO (eq VMProtect 2-3), when there were no lifters and other modern devirtualisation tools. DENUVO_Profiler is a subsequent development of the SecuROM_Profiler utility - the simplest tool for visualising the operation of a virtual machine and effectively controlling the data it uses in the byte-code tape (p-code). DENUVO_Profiler also hunts for Electronic... -
