END

// Checks whether the selected certificate is valid for signing
IF MyCertificate.ValidForSignature = False THEN
	Info("The selected certificate cannot be used to generate a signature.")
	RETURN
END

// Retrieve the buffer containing the signature
bufSignature is Buffer
bufSignature = CertificateSignFile(FullFileName, MyCertificate)


// Check the signature
SWITCH CertificateCheckFileSignatureBuffer(FullFileName, bufSignature)
	CASE certificateOk: Info("Valid signature and reliable certificate")
	CASE certificateInvalid: Info("Invalid signature or certificate")
	CASE certificateExpired: Info("Valid signature but certificate expired")
	CASE certificateUntrusted: Info("Valid signature but trusted root "+  ...
		"of certificate not reliable")
