title: Base64 digest + PFX(PKCS12) -> ETSI.CAdES.detached signature -> PAdES LTV
body: <p>I have an API that creates Base64 digest of a PDF Document.
  Now I want to create another API that takes this digest and PFX and creates an ETSI.CAdES.detached signature and takes LTV informations(Certs chain,OCSP response,CRL) that I want to embed in my PDF to obtain a PAdES-LTV signature using 3rd API(My 3rd API will take CAdES signature and LTV informations obtained from this API and will embed them in my PDF).I dont know how to create this ETSI.CAdES.detached signature using that digest and a PFX with Java and Bouncy Castle.I try to follow this <a href="https://github.com/eideasy/eideasy-external-pades-digital-signatures" rel="nofollow noreferrer">github</a> tutorial.</p>
