## Overview

Implementation-independent abstractions for main cryptographic algorithms used 
for end-to-end encryption and authorization:
- Algorithms based on Edwards curves:
  - ECDH with X25519 scheme using Curve25519 keys
  - EdDSA signatures with Ed25519 sheme using Edwards25519 keys
- Algorithms based on NSA Secp256k1 curve:
  - ECDH with normal Secp256k1 keys
  - ECDSA signatures with normal Secp256k1 keys
  - Schnorr signatures with BIP340 scheme and x-only public keys
- Digest algorithms with a unified API
  - SHA2: SHA256 & SHA512
  - SHA3: SHA3-256 & SHA3-512
  - Blake3

The library is a part of [rust cyphernet suite](https://github.com/Cyphernet-DAO/rust-cyphernet)
and used by other libraries of the suite for handling internet addresses.
