Argon2 is a hashing algorithm, primarily for password hashing. Use with specific language tags for questions regarding implementation

Argon2 is a hashing algorithm designed for the Password Hashing Competition, which it ultimately won. From the GitHub repository

Argon2 is a password-hashing function that summarizes the state of the art in the design of memory-hard functions and can be used to hash passwords for credential storage, key derivation, or other applications.

It has a simple design aimed at the highest memory filling rate and effective use of multiple computing units, while still providing defense against tradeoff attacks (by exploiting the cache and memory organization of the recent processors).

Argon2 has been implemented in a number of programming languages. Questions should pertain to using it within those languages.

How do I use the Argon2 algorithm with password_hash?

So I heard that PHP 7.2 introduced the new Argon2 algorithm. But I'm confused on how I can use it with my existing code. For instance, I have this $password = password_hash('somepassword', PASSWORD_DEFAULT, ['cost' => 12]); Does PASSWORD_DEFAULT…

How do I correctly adjust the Argon2 parameters in Go to consume less memory?

Argon2 by design is memory hungry. In the semi-official Go implementation, the following parameters are recommended when using IDKey: key := argon2.IDKey([]byte("some password"), salt, 1, 64*1024, 4, 32) where 1 is the time parameter and 64*1024 is…

Maximum input and output length for Argon2

As you may know, maximum input length for bcrypt is 72 characters and the output length is 60 characters. (I've it tested in PHP. Correct me if I'm wrong) I want to know maximum input length and the exact output length for argon2. Thanks.

Java Argon2 Hashing

I'm trying to figure out how to practically use argon2 hashing for passwords in Java. I've got to be missing something, because none of the APIs return discrete fields for the hash or the salt. I've tried both a JVM binding for argon2 and also…
