Verifies a timestamp token by checking the signature, validating the certificate chain implied by tsa_certificate and by checking conformance to a given Request. Mandatory parameters are the Request associated to this Response, and an OpenSSL::X509::Store of trusted roots.
Intermediate certificates can optionally be supplied for creating the certificate chain. These intermediate certificates must all be instances of OpenSSL::X509::Certificate.
If validation fails, several kinds of exceptions can be raised:
TypeError if types don’t fit
TimestampError if something is wrong with the timestamp token itself, if it is not conformant to the Request, or if validation of the timestamp certificate chain fails.
Returns the ‘short name’ of the object identifier representing the algorithm that was used to derive the message imprint digest. For valid timestamps, this is the same value that was already given in the Request. If status is GRANTED or GRANTED_WITH_MODS, this is never nil.
algo = token_info.algorithm puts algo -> "SHA1"
If the ordering field is missing, or if the ordering field is present and set to false, then the genTime field only indicates the time at which the time-stamp token has been created by the TSA. In such a case, the ordering of time-stamp tokens issued by the same TSA or different TSAs is only possible when the difference between the genTime of the first time-stamp token and the genTime of the second time-stamp token is greater than the sum of the accuracies of the genTime for each time-stamp token.
If the ordering field is present and set to true, every time-stamp token from the same TSA can always be ordered based on the genTime field, regardless of the genTime accuracy.
Allows to set the object identifier or the ‘short name’ of the algorithm that was used to create the message imprint digest.
request.algorithm = "SHA1"
Returns the ‘short name’ of the object identifier that represents the algorithm that was used to create the message imprint digest.
Performs a certificate verification on the OpenSSL::X509::Certificate cert.
chain can be an array of OpenSSL::X509::Certificate that is used to construct the certificate chain.
If a block is given, it overrides the callback set by verify_callback=.
After finishing the verification, the error information can be retrieved by error, error_string, and the resulting complete certificate chain can be retrieved by chain.
Restore session state from the session’s FileStore file.
Returns the session state as a hash.
Restore (empty) session state.
Restore session state from the session’s PStore file.
Returns the session state as a hash.
Returns true if the listing commands, LIST, NLST, and MLSD are applied to the directory.
Returns true if the STOR command may be applied to the file.
