This package is part of [ZHaskell](https://z.haskell.world) project, providing comprehensive crypto primitives based on [botan](https://github.com/randombit/botan).

* Random number generators.
* Block Cipher and symmetric cipher.
* Hash.
* MAC.
* Key derivation functions.
* Password hash.
* Multiple precision integers.
* Public key creation, import and export.
* Public key encryption/decryption
* Diffie-Hellman key exchange.
* Signature generation & signature verification.
* X.509 certificates & X.509 certificate revocation lists.
* One time password.
* AES Key Wrapping
* Format Preserving Encryption.

## Requirements

* A working haskell compiler system, GHC(>=8.6), cabal-install(>=3.2.1), hsc2hs.

* A working python interpreter in `$PATH`.

* Tests need [hspec-discover](https://hackage.haskell.org/package/hspec-discover).

## Example usage

```haskell
> :set -XOverloadedLists
> :m + Z.Crypto.Hash 
>
> hash SHA256 "hello, world"
