(This class only supports generating "Type I" argon2 hashes). Argon2 supports a variable-length salt, and variable time & memory cost, and a number of other configurable parameters. The :meth:`~passlib.ifc.PasswordHash.replace` method accepts the following optional keywords: :type salt: str :param salt: Optional salt string. If specified, the length must be between 0-1024 bytes. If not specified, one will be auto-generated (this is recommended). :type salt_size: int :param salt_size: Optional number of bytes to use when autogenerating new salts. :type rounds: int :param rounds: Optional number of rounds to use. This corresponds linearly to the amount of time hashing will take. :type time_cost: int :param time_cost: An alias for **rounds**, for compatibility with underlying argon2 library. :param int memory_cost: Defines the memory usage in kibibytes. This corresponds linearly to the amount of memory hashing will take. :param int parallelism: Defines the parallelization factor. *NOTE: this will affect the resulting hash value.* :param int digest_size: Length of the digest in bytes. :param int max_threads: Maximum number of threads that will be used. -1 means unlimited; otherwise hashing will use ``min(parallelism, max_threads)`` threads. .. note:: This option is currently only honored by the argon2pure backend. :type relaxed: bool :param relaxed: By default, providing an invalid value for one of the other keywords will result in a :exc:`ValueError`. If ``relaxed=True``, and the error can be corrected, a :exc:`~passlib.exc.PasslibHashWarning` will be issued instead. Correctable errors include ``rounds`` that are too small or too large, and ``salt`` strings that are too long. .. todo:: * Support configurable threading limits.
