Sig.VerifyOpts opts = Sig.VerifyOpts.Default
)
[VB]
Public Shared Function VerifyFile (
sigStr As String,
dataFile As String,

Optional opts As Sig.VerifyOpts = Sig.VerifyOpts.Default
) As Integer
Parameters
- sigStr String
- Containing the encoded signature value
- dataFile String
- Name of file containing data to be verified
- certOrKeyFile String
