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.
|
|
Args:
|
secret: Secret to hash.
|
|
salt: A salt_. Should be random and different for each secret.
|
|
type: Which Argon2 variant to use.
|
|
version: Which Argon2 version to use.
|
|
For an explanation of the Argon2 parameters see
|
:class:`argon2.PasswordHasher`.
|
|
Returns:
|
An encoded Argon2 hash.
|
|
Raises:
|
argon2.exceptions.HashingError: If hashing fails.

|
Verify whether *secret* is correct for *hash* of *type*.
|
|
Args:
|
hash:
|
An encoded Argon2 hash as returned by :func:`hash_secret`.
|
|
secret:
|
The secret to verify whether it matches the one in *hash*.
|
|
type: Type for *hash*.
|
|
Raises:
|
argon2.exceptions.VerifyMismatchError:
|
If verification fails because *hash* is not valid for *secret* of
|
*type*.
|
|
argon2.exceptions.VerificationError:
|
If verification fails for other reasons.
|
|
Returns:
|
``True`` on success, raise :exc:`~argon2.exceptions.VerificationError`
|
otherwise.
|
|
.. versionadded:: 16.0.0
|
.. versionchanged:: 16.1.0
|
Raise :exc:`~argon2.exceptions.VerifyMismatchError` on mismatches
|
instead of its more generic superclass.

|
Direct binding to the ``argon2_ctx`` function.
|
|
.. warning::
|
This is a strictly advanced function working on raw C data structures.
|
Both Argon2's and *argon2-cffi*'s higher-level bindings do a lot of
|
sanity checks and housekeeping work that *you* are now responsible for
|
(e.g. clearing buffers). The structure of the *context* object can,
|
has, and will change with *any* release!
|
|
Use at your own peril; *argon2-cffi* does *not* use this binding
|
itself.
|
|
Args:
|
context:
|
A CFFI Argon2 context object (i.e. an ``struct Argon2_Context`` /
|
``argon2_context``).
|
|
type:
|
Which Argon2 variant to use. You can use the ``value`` field of
|
:class:`Type`'s fields.
|
|
Returns:
|
An Argon2 error code. Can be transformed into a string using
|
:func:`error_to_str`.
