The VerifyEXE method checks if valid digital signature exists in
Data blob. If such signature is found, VerifyEXE will try to perform
various tests to make sure data has not been tampered with, signer's
certificate has not expired, etc.. If signature is valid, this
method will successfully return Certificate
object containing reference to signer's certificate.
Performing verification is easy since there are no requirements
for it - you should just load the file and call VerifyEXE on it.
- Dim inblob As New FileBlob
inblob.FileName = "path.to.signed.dll"
Dim Crypt1 As New wodCryptCom
Dim cert As Certificate
Set cert = Crypt1.VerifyEXE(inblob)
If Not cert Is Nothing Then cert.Show "Signer's certificate"
Above code would produce an error if certificate is invalid.
You can use SignEXE
method to sign the data, or any other external tool such as 'signcode.exe'
