fun validateSignatureAsync(digitalSignatureInfo: DigitalSignatureInfo): Single<DigitalSignatureValidationResult>

Validates passed digital signature. Signature certificate is validated in according to root CA certificates passed to TrustedKeyStore. This may take a bit of time so it shouldn't be run on main thread. This method does not operate on any particular scheduler, so use Single.subscribeOn to offload validation to a different thread.
