What is Argon2?
Argon2 is a password hashing algorithm that was developed by a team of researchers led by Alex Biryukov and Daniel Dinu at the University of Luxembourg. It was the winner of the Password Hashing Competition (PHC) in 2015, a competition organized to select a new password hashing algorithm to replace the outdated and insecure algorithms such as MD5 and SHA-1.
Argon2 is designed to be resistant to various types of attacks such as brute force attacks, timing attacks, and side-channel attacks. It uses a unique combination of memory-hard and time-hard functions to make it computationally expensive and time-consuming to crack. This makes it an ideal choice for password hashing in cryptocurrency and blockchain applications, where security is of the utmost importance.

Features of Argon2
1. Memory-hard: Argon2 is a memory-hard algorithm, which means that it requires a large amount of memory to perform the hashing operation. This makes it difficult for attackers to use specialized hardware to crack the password hash.
2. Time-hard: Argon2 is also a time-hard algorithm, which means that it requires a significant amount of time to perform the hashing operation. This makes it resistant to brute force attacks, where attackers try to guess the password by trying all possible combinations.
3. Tunable parameters: Argon2 has several tunable parameters that allow users to adjust the memory usage, time consumption, and parallelism of the algorithm. This makes it flexible and adaptable to different use cases and security requirements.
