FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Implementation details

ECDSA is using deterministic k value generation as per RFC6979. Most of the curve operations are performed on non-affine coordinates (either projective or extended), various windowing techniques are used for different cases.

NOTE: curve25519 could not be used for ECDSA, use ed25519 instead.

All operations are performed in reduction context using bn-php.

API

ECDSA

EdDSA

ECDH

NOTE: .derive() returns a BN instance. The resulting hex string is not zero-padded to constant size. Note that when interoperating with other libraries or using the result in a hash function.

Using EC directly

Use case examples:

Computing public key from private

Verifying Bitcoin Message Signature

Verifying Ethereum Signature

ECDH (secret based, base58 format)

For usage in ed25519 oriented platforms like e.g. BigChainDB who use base58 encoded public / private keys.
