bcryptīased on the Blowfish cipher, bcrypt was designed by Niels Provos and David Mazières in 1999. The Argon2 algorithm can take a number of configurable parameters, such as memory, iterations, parallelism, salt length, and key length. Argon2id is a hybrid of Argon2i and Argon2id, allowing it to provide a more balanced approach to resisting both side-channel and GPU-based attacks. It has three variations, namely Argon2d, Argon2i, and Argon2id.

Argon2idĪrgon2 is the hashing algorithm that won the 2015 Password Hashing Competition (PHC). The Open Web Application Security Project (OWASP) has listed some hash algorithms designed for storing passwords such as Argon2id, bcrypt, and PBKDF2t. Although MD5 is no longer used for password hashing, it can still be used to verify data integrity. Furthermore, major players in the field have also identified some vulnerabilities in these algorithms and therefore advise against the adoption of MD5, SHA-1 and SHA-2 for password hashing. Having a fast hash algorithm means that it takes less computational efforts for attackers to “decrypt” the hash.
However, these were designed to be quick. In the early days, Message Digest (MDx) algorithms, such as MD5, and Secure Hash Algorithms (SHA), such as SHA-1 and SHA-2, were used quite often to hash passwords.
As mentioned above, hash algorithms are one-way functions that convert a new string of characters with a fixed length.
