EOS Elliptic-curve cryptography PHP library
===========================================

[](#eos-elliptic-curve-cryptography-php-library)

Introduction
------------

[](#introduction)

Elliptic-curve cryptography (ECC) is used by the EOS Blockchain to implement Public/Private key encryption. However EOS does abit more than just standard ECC.

This library was written to address this. it's basicly a wrapper around a generic ECC implemention. [paragonie/ecc](https://packagist.org/packages/paragonie/ecc) to be more exact, however the API never exposes this so it could change at any time without the code using this library will have to change.

This library exposes mainly 3 classes that you will deal with.

- PublicKey
- PrivateKey
- Signature

Here is a quick list of what EOS/Blockchain specific functionality is included in this library:

- Encode/Decode WIF (Wallet import format, [Base58](https://en.wikipedia.org/wiki/Base58)) Signatures,Private keys and Public keys.
- Ripe160md/Double Sha256 checksum used in WIF.
- Public Key recovery from Signatures.
- Canonical Signatures.

And of course on top of this standard functionality for a ECC library like signing messages, verifying signatures and so on.

Install
-------
