CLI === To aid you with finding the parameters, ``argon2_cffi`` offers a CLI interface that can be accessed using ``python -m argon2``. It will benchmark Argon2’s password *verification* in the current environment. You can use command line arguments to set hashing parameters: .. code-block:: text $ python -m argon2 Running Argon2id 100 times with: hash_len: 16 bytes memory_cost: 102400 KiB parallelism: 8 threads time_cost: 2 iterations Measuring... 45.3ms per password verification This should make it much easier to determine the right parameters for your use case and your environment.
