Argon2 Hash Generator
Generate Argon2 password hashes with configurable parameters
Input
Argon2 is the winner of the Password Hashing Competition and is considered one of the most secure modern algorithms for hashing passwords, designed to resist both brute-force and specialized hardware attacks (like GPU cracking). This tool generates and verifies Argon2 hashes for testing or learning purposes.
Frequently asked questions
Both are designed to be slow/resistant to brute-force attacks, but Argon2 is newer and specifically tunable for memory usage as well as time cost, making it more resistant to attacks using specialized hardware like GPUs, which is why many modern systems prefer it over BCrypt.
They control how much computing resources are required to compute the hash - higher values make it slower and more resource-intensive to brute-force, at the cost of also being slower for legitimate use.
Hashing runs in your browser, but avoid pasting real production passwords into any third-party tool as a general precaution - use test values when exploring how Argon2 behaves.
