Argon2 Hash Generator

Argon2 is a modern password-hashing function that won the Password Hashing Competition in 2015. It provides strong protection against brute-force attacks using memory-hard and time-consuming operations.

Generate Argon2 Hash
Argon2id is recommended for password hashing. It combines benefits of Argon2i and Argon2d.
Higher memory cost = more secure but slower. Minimum recommended: 64MB for secure password storage.
Number of iterations. Higher = more secure but slower. Minimum recommended: 3 iterations.
Number of parallel threads. Adjust based on your CPU cores. Typical: 4 threads.

What is Argon2?

Argon2 is the winner of the Password Hashing Competition (PHC) held in 2015. It was designed to be resistant to GPU cracking attacks and side-channel attacks. Argon2 comes in three variants: Argon2d (data-dependent), Argon2i (data-independent), and Argon2id (hybrid version).

Argon2id is the recommended variant as it provides protection against both side-channel and time-memory trade-off attacks. It's used by many modern applications and password managers for secure password storage.

Key Features
  • Winner of Password Hashing Competition 2015
  • Three variants: Argon2d, Argon2i, and Argon2id (recommended)
  • Configurable memory cost, time cost, and parallelism
  • Resistant to GPU, ASIC attacks and side-channel attacks
Security Information

Argon2id is recommended for password hashing as it provides balanced protection.

For most applications, use: memory=64MB, time=3, parallelism=4 as minimum secure parameters.

Always use a unique random salt for each password (minimum 16 bytes).
