Struct PyPbkdf2ParamsBuilder 

pub struct PyPbkdf2ParamsBuilder { /* private fields */ }

Python-facing wrapper for synta_certificate::Pbkdf2ParamsBuilder.

Builds a DER-encoded Pkcs5Pbkdf2Params SEQUENCE (RFC 8018 §5.2).

Required fields: salt and iteration_count. Optional: key_length, prf (absent means HMAC-SHA-1 per RFC 8018 default).

Use :meth:build to produce the raw PBKDF2-params DER, or :meth:build_as_algorithm_identifier to wrap it in an AlgorithmIdentifier for use as the keyDerivationFunc field in :class:Pbes2ParamsBuilder.

Example::

import synta
import synta.pkcs5 as pkcs5

params_der = (
    synta.Pbkdf2ParamsBuilder()
    .salt(b"\\x01\\x02\\x03\\x04\\x05\\x06\\x07\\x08")
    .iteration_count(10_000)
    .key_length(32)
    .prf(list(pkcs5.ID_HMAC_WITH_SHA256.components()))
    .build()
)

Docstring for the class provided on the struct or enum.

const DOC: &'static CStr

Fully rendered class doc, including the text_signature if a constructor is defined.

type BaseType = PyAny

Base class

type ThreadChecker = SendablePyClass<PyPbkdf2ParamsBuilder>

This handles following two situations:

type PyClassMutability = <<PyAny as PyClassBaseType>::PyClassMutability as PyClassMutability>::MutableChild

Immutable or mutable

type Dict = PyClassDummySlot

Specify this class has #[pyclass(dict)] or not.

type WeakRef = PyClassDummySlot

Specify this class has #[pyclass(weakref)] or not.

type BaseNativeType = PyAny

The closest native ancestor. This is PyAny by default, and when you declare #[pyclass(extends=PyDict)], it’s PyDict.
