Argon2
Reference C implementation of Argon2, the memory-hard password hashing function that won the Password Hashing Competition.
What is Argon2?
Argon2 is a password-hashing function designed to be memory-hard, making it resistant to GPU and ASIC cracking attacks. It won the Password Hashing Competition (PHC) and is used for securely storing passwords, deriving keys, and other cryptographic applications. The project provides the reference C implementation, including libraries and a command-line tool.
Developers and system architects building secure authentication systems, password managers, or cryptographic applications that require robust password storage and key derivation.
It offers state-of-the-art security with tunable parameters, multiple variants for different threat models, and a well-vetted design as the PHC winner, ensuring reliability and resistance to modern attack vectors.
