#add_nonce(nonce = nil) ⇒ Object

Adds a nonce to the OCSP request. If no nonce is given a random one will be generated.

The nonce is used to prevent replay attacks but some servers do not support it.

#check_nonce(response) ⇒ Object

Checks the nonce validity for this request and response.

The return value is one of the following:

-1

nonce in request only.

0

nonces both present and not equal.

1

nonces present and equal.

2

nonces both absent.

3

nonce present in response only.

For most responses, clients can check result > 0. If a responder doesn’t handle nonces result.nonzero? may be necessary. A result of 0 is always an error.

#sign(cert, key, certs = nil, flags = 0, digest = nil) ⇒ self

Signs this OCSP request using cert, key and optional digest. If digest is not specified, SHA-1 is used. certs is an optional Array of additional certificates which are included in the request in addition to the signer certificate. Note that if certs is nil or not given, flag OpenSSL::OCSP::NOCERTS is enabled. Pass an empty array to include only the signer certificate.

flags is a bitwise OR of the following constants:

OpenSSL::OCSP::NOCERTS

Don’t include any certificates in the request. certs will be ignored.

Returns:

  • (self)

#signed? ⇒ Boolean

Returns true if the request is signed, false otherwise. Note that the validity of the signature is not checked. Use #verify to verify that.

#verify(certificates, store, flags = 0) ⇒ Boolean

Verifies this request using the given certificates and store. certificates is an array of OpenSSL::X509::Certificate, store is an OpenSSL::X509::Store.

Note that false is returned if the request does not have a signature. Use #signed? to check whether the request is signed or not.

Returns:
