Struct PyHOTP 

pub struct PyHOTP { /* private fields */ }

HMAC-based One-Time Password generator (RFC 4226).

Generates and verifies counter-based OTPs using HMAC-SHA1 (default), HMAC-SHA256, HMAC-SHA384, or HMAC-SHA512.

import synta.crypto

# RFC 4226 test vector — key is the ASCII string "12345678901234567890"
key = bytes.fromhex("3132333435363738393031323334353637383930")
hotp = synta.crypto.HOTP(key, digits=6, algorithm="sha1")
print(hotp.generate(0))    # "755224"
print(hotp.generate(1))    # "287082"
# Verify with look-ahead window of 5:
next_counter = hotp.verify("287082", counter=0, look_ahead=5)
assert next_counter == 1

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<PyHOTP>

This handles following two situations:

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

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.

Checks if object is an instance of this type or a subclass of this type.

fn is_exact_type_of(object: &Bound<'_, PyAny>) -> bool

Checks if object is an instance of this type.
