This package provides a pure PHP interface to BIP70.

It exposes classes for:

  • X509 routines
    • loading a trusted certificate store
    • CA chain validation of X509Certificates
    • X509 signature validation of Signature and X509Certificate
  • for extracting, parsing, and manipulating protobufs
  • for downloading and fully validating a payment request over HTTP(s)
  • creating (un)signed payment requests

Note: this library should not be considered stable until the v1.0.0 release. Outstanding issues are tracked using the v1.0.0 milestone.
