Verifies the signature of the certificate, with the public key key. key must be an instance of OpenSSL::PKey.
Checks that cert signature is made with PRIVversion of this PUBLIC ‘key’
key - the public key to be used for verifying the SPKI signature
Returns true if the signature is valid, false otherwise. To verify an SPKI, the public key contained within the SPKI should be used.
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.
Verifies the signature of the response using the given certificates and store. This works in the similar way as OpenSSL::OCSP::Request#verify.
Returns the serial number of the certificate for which status is being requested.
Verifies the signature for the data using a message digest algorithm digest and a public key pkey.
Returns true if the signature is successfully verified, false otherwise. The caller must check the return value.
See sign for the signing operation and an example.
See also the man page EVP_DigestVerify(3).
Derives a shared secret from pkey and peer_pkey. pkey must contain the private components, peer_pkey must contain the public components.
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.
Sets the store’s default verification purpose. If specified, the verifications on the store will check every certificate’s extensions are consistent with the purpose. The purpose is specified by constants:
X509::PURPOSE_SSL_CLIENT
X509::PURPOSE_SSL_SERVER
X509::PURPOSE_NS_SSL_SERVER
X509::PURPOSE_SMIME_SIGN
X509::PURPOSE_SMIME_ENCRYPT
X509::PURPOSE_CRL_SIGN
X509::PURPOSE_ANY
X509::PURPOSE_OCSP_HELPER
X509::PURPOSE_TIMESTAMP_SIGN
OpenSSL::X509::StoreContext#purpose= can be used to change the value for a single verification operation.
See also the man page X509_VERIFY_PARAM_set_purpose(3).
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.
