tagLength

Why do I need to specify a tagLength to generate a hash? What do I put there? This is not in the usage guide...

commented

The tagLength is the size of the hash output in bytes, the recommended default in the argon2 spec (section 9, bullet point 6) is 32.

Edit: The spec actually recommends 128 bits (16 bytes) as a default, their CLI defaults to 32 bytes.
