SigAlgorithm sigAlg,
Sig.VerifyOpts opts
)

sigStr As String, _
dataFile As String, _
certOrKeyFile As String, _
sigAlg As SigAlgorithm, _
opts As Sig.VerifyOpts _
) As Integer
Parameters
- sigStr
- Containing the encoded signature value
- dataFile
- Name of file containing data to be verified
- certOrKeyFile
- Specifying the X.509 certificate or public key file name (or a string containing the certificate or key in PEM format or base64 representation, or an internal key string).
