libsodium
A modern, portable, easy to use crypto library
libsodium is a modern, portable, and easy-to-use cryptographic library that serves as an API-compatible fork of NaCl. Consistent behavior and formats across supported platforms. It enhances the original design with build and portability improvements, making it widely deployable across platforms for secure encryption, signatures, hashing, and key derivation. Digital signature creation and verification support. Adds extended cryptographic primitives like BLAKE2 and ChaCha20-Poly1305 beyond NaCl. -

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).... -

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

VeraCrypt
Open source disk encryption with strong security for the Paranoid
VeraCrypt is a free disk encryption software brought to you by IDRIX (https://www.idrix.fr) and based on TrueCrypt 7.1a. It adds enhanced security to the algorithms used for system and partitions encryption making it immune to new developments in brute-force attacks. It also solves many vulnerabilities and security issues found in TrueCrypt. This enhanced security adds some delay ONLY to the opening of encrypted partitions without any performance impact to the application use phase.... -

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... -
