The documentation for pbkdf2_hmac at uses the "rounds" keyword:

hashlib.pbkdf2_hmac(name, password, salt, rounds, dklen=None)

However, the actual source code uses "iterations". No-one has probably noticed it before because no error is raised if the number of iterations is given as a positional argument.

Thanks for the patch. The documentation still mentions *rounds* in one place, which I presume was meant to be a direct reference to the parameter.

Good catch. I updated that reference now from rounds to iterations as well.

Here is an updated patch. I also fixed the hash_name parameter, some more minor offences in the documentation, and added a test case.
