Information

This library is a rewrite/update of Matyas Danter's ECC library. All credit goes to him., (*4)

For more information on Elliptic Curve Cryptography please read this fine article., (*5)

The library supports the following curves:, (*6)

  • secp112r1
  • secp256k1
  • nistp192
  • nistp224
  • nistp256 / secp256r1
  • nistp384 / secp384r1
  • nistp521

During ECDSA, a random value k is required. It is acceptable to use a true RNG to generate this value, but should the same k value ever be repeatedly used for a key, an attacker can recover that signing key. The HMAC random generator can derive a deterministic k value from the message hash and private key, voiding this concern., (*7)

The library uses a non-branching Montgomery ladder for scalar multiplication, as it's constant time and avoids secret dependant branches., (*8)

License

This package is released under the MIT license., (*9)

Requirements

  • PHP 7.0+ or PHP 8.0+
  • composer
  • ext-gmp

Support for older PHP versions: * v0.4.x: php ^5.6|<7.2 * v0.5.x: php ^7.0 * v1.0.x: php ^7.0|^8.0, (*10)

Installation

You can install this library via Composer :, (*11)

composer require mdanter/ecc:^1.0, (*12)

Contribute

When sending in pull requests, please make sure to run the make command., (*13)

The default target runs all PHPUnit and PHPCS tests. All tests must validate for your contribution to be accepted., (*14)

It's also always a good idea to check the results of the Scrutinizer analysis for your pull requests., (*15)

Usage

Examples: * Key generation * ECDH exchange * Signature creation * Signature verification, (*16)
