class int(object)
| int([x]) -> integer
| int(x, base=10) -> integer
|
| Convert a number or string to an integer, or return 0 if no arguments
| are given. If x is a number, return x.__int__(). For floating-point
| numbers, this truncates towards zero.
|
| If x is not a number or if base is given, then x must be a string,
| bytes, or bytearray instance representing an integer literal in the
| given base. The literal can be preceded by '+' or '-' and be surrounded
| by whitespace. The base defaults to 10. Valid bases are 0 and 2-36.
| Base 0 means to interpret the base from the string as an integer literal.
| >>> int('0b100', base=0)

|
| High level class to hash passwords with sensible defaults.
|
| Uses Argon2\ **id** by default and always uses a random salt_ for hashing.
| But it can verify any type of Argon2 as long as the hash is correctly
| encoded.
|
| The reason for this being a class is both for convenience to carry
| parameters and to verify the parameters only *once*. Any unnecessary
| slowdown when hashing is a tangible advantage for a brute force attacker.
|
| :param int time_cost: Defines the amount of computation realized and
| therefore the execution time, given in number of iterations.
| :param int memory_cost: Defines the memory usage, given in kibibytes_.
| :param int parallelism: Defines the number of parallel threads (*changes*
| the resulting hash value).
| :param int hash_len: Length of the hash in bytes.
| :param int salt_len: Length of random salt to be generated for each
| password.
| :param str encoding: The Argon2 C library expects bytes. So if
| :meth:`hash` or :meth:`verify` are passed a ``str``, it will be
| encoded using this encoding.
| :param Type type: Argon2 type to use. Only change for interoperability
| with legacy systems.
|
| .. versionadded:: 16.0.0

| Switch from Argon2i to Argon2id based on the recommendation by the

argon2-cffi.low_level
Python Library Documentation: module argon2.low_level in argon2
NAME
argon2.low_level - Low-level functions if you want to build your own higher level abstractions.
DESCRIPTION
.. warning::
This is a "Hazardous Materials" module. You should **ONLY** use it if
you're 100% absolutely sure that you know what you're doing because this
module is full of land mines, dragons, and dinosaurs with laser guns.
CLASSES
enum.Enum(builtins.object)
argon2.Type
class Type(enum.Enum)
| Type(*values)
|
| Enum of Argon2 variants.
|
| Please see :doc:`parameters` on how to pick one.
|
| Method resolution order:
| Type
| enum.Enum
| builtins.object
|
| Data and other attributes defined here:
|
| D = <Type.D: 0>
|
| I = <Type.I: 1>
|
| ID = <Type.ID: 2>
|
| ----------------------------------------------------------------------
| Data descriptors inherited from enum.Enum:
|
| name
| The name of the Enum member.
|
| value
| The value of the Enum member.
|
| ----------------------------------------------------------------------
| Static methods inherited from enum.EnumType:
|
| __contains__(value)
| Return True if `value` is in `cls`.
|
| `value` is in `cls` if:
| 1) `value` is a member of `cls`, or
| 2) `value` is the value of one of the `cls`'s members.
|
| __getitem__(name)
| Return the member matching `name`.
|
| __iter__()
| Return members in definition order.
|
| __len__()
| Return the number of members (no aliases)
|
| ----------------------------------------------------------------------
| Readonly properties inherited from enum.EnumType:
|
| __members__
| Returns a mapping of member name->value.
|
| This mapping lists all enum members, including aliases. Note that this
| is a read-only view of the internal mapping.
FUNCTIONS
hash_secret(secret: 'bytes', salt: 'bytes', time_cost: 'int', memory_cost: 'int', parallelism: 'int', hash_len: 'int', type: 'Type', version: 'int' = 19) -> 'bytes'
Hash *secret* and return an **encoded** hash.
An encoded hash can be directly passed into :func:`verify_secret` as it
contains all parameters and the salt.
:param bytes secret: Secret to hash.
:param bytes salt: A salt_. Should be random and different for each
secret.
:param Type type: Which Argon2 variant to use.
:param int version: Which Argon2 version to use.
For an explanation of the Argon2 parameters see
:class:`argon2.PasswordHasher`.
:rtype: bytes
:raises argon2.exceptions.HashingError: If hashing fails.
.. versionadded:: 16.0.0
.. _salt: https://en.wikipedia.org/wiki/Salt_(cryptography)
.. _kibibytes: https://en.wikipedia.org/wiki/Binary_prefix#kibi
hash_secret_raw(secret: 'bytes', salt: 'bytes', time_cost: 'int', memory_cost: 'int', parallelism: 'int', hash_len: 'int', type: 'Type', version: 'int' = 19) -> 'bytes'
Hash *password* and return a **raw** hash.
This function takes the same parameters as :func:`hash_secret`.
.. versionadded:: 16.0.0
verify_secret(hash: 'bytes', secret: 'bytes', type: 'Type') -> 'Literal[True]'
Verify whether *secret* is correct for *hash* of *type*.
:param bytes hash: An encoded Argon2 hash as returned by
:func:`hash_secret`.
:param bytes secret: The secret to verify whether it matches the one
in *hash*.
:param Type type: Type for *hash*.
:raises argon2.exceptions.VerifyMismatchError: If verification fails
because *hash* is not valid for *secret* of *type*.
:raises argon2.exceptions.VerificationError: If verification fails for
other reasons.
:return: ``True`` on success, raise
:exc:`~argon2.exceptions.VerificationError` otherwise.
:rtype: bool
.. versionadded:: 16.0.0
.. versionchanged:: 16.1.0
Raise :exc:`~argon2.exceptions.VerifyMismatchError` on mismatches
instead of its more generic superclass.
