The SLH-DSA project implements the stateless-hash digital signing algorithm(standardizing fips 205, adopted on Sphincs-Plus algorithm) in pure Python.

This project offers those future:

1. 🍻 Zero dependencies!

2. 🏷️ 100% type hint for all the codes!

3. ✅ Complete 100% test coverage!

4. 🔖 Support any newer python version!

5. ⚒️ Design for Human!

6. 🎉 More futures coming soon!

The functionality is extremely simple to use, as demonstrated by the following example:

```python

from slhdsa import KeyPair, shake_256f, PublicKey

kp = KeyPair.gen(shake_256f)  # generate the keypair

sig = kp.sign(b"Hello World!")  # sign the message

kp.verify(b"Hello World!", sig)  # -> True

kp.verify(b"Hello World!", b"I'm the hacker!") # -> False

kp.verify(b"hello world!", sig)  # -> False

sig = kp.sign(b"Hello World!", randomize = True)  # sign the message randomized

kp.verify(b"Hello World!", sig)  # -> True

digest = kp.pub.digest()  # generate the digest of the public key so that other device could verify the sign

pub = PublicKey.from_digest(digest, shake_256f)  # recovery public key

pub.verify(b"Hello World!", sig)  # -> True

pub.verify(b"Hello World", sig)  # -> False

```
