aiwozhe/phactor (packagist): Phactor is a high-performance PHP implementation of the elliptic curve math functions required to generate & verify private/public (asymmetric) EC keypairs and ECDSA signatures based on secp256k1 curve parameters. This library also includes a class to generate Service Identification Numbers (SINs) based on the published Identity Protocol v1 spec.
