Verify Method
Verifies a digitally signed CAdES message.
Syntax
public func verify() throws -> Void
Remarks
CAdESVerifier supports two types of signatures: enveloping and detached. In the enveloping case, both the data and the signature travel in the same 'combined' message. The detached variant observes the signature and the data (in its original form) residing in different files.
Call this method to verify enveloping signatures provided via InputStream or InputFile property, and extract the embedded data to OutputFile or OutputStream. Use VerifyDetached to verify detached signatures.
