        # OpenSSL::OCSP::BasicResponse.sign

(from ruby core)
### Implementation from BasicResponse
---
    basic_response.sign(cert, key, certs = nil, flags = 0, digest = nil) -> self

---

Signs this OCSP response using the *cert*, *key* and optional *digest*.
This behaves in the similar way as OpenSSL::OCSP::Request#sign.

*flags* can include:
OpenSSL::OCSP::NOCERTS
:   don't include certificates
OpenSSL::OCSP::NOTIME
:   don't set producedAt
OpenSSL::OCSP::RESPID_KEY
:   use signer's public key hash as responderID
