Password Hash

Hash a password with Argon2 or bcrypt, or check a password against a hash

Hash Verify

Password

Enter a password.

Algorithm

Argon2id Argon2i Argon2d bcrypt

The recommended choice (RFC 9106, OWASP): slow to crack on GPUs, and resists side-channel attacks.

Memory

MiB

Between 1 and 1024 MiB.

Iterations

Between 1 and 100.

Parallelism

Between 1 and 16.

RFC 9106 recommends 64 MiB, 3 iterations and a parallelism of 4; OWASP's minimum is 19 MiB, 2 iterations and 1. A random 16-byte salt, a 32-byte hash.
