#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.
