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. mdanter/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) 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

You can install this using composer:

composer require eosswedenorg/eos-ecc
