Adobe Acrobat doesn't recognize CRL/OCSP responses for PSS

[Israr_Iftikhar]

Hi,

I have signed PAdES LTV documents when I opened it in Adobe Acrobat, it doesn't recognize the embedded revocation although the CRL/OCSP responses are embedded in DSS dictionary. Both CRL and OCSP Responses are signed with RSA keys (PSS Padding). It seems Adobe Acrobat doesn't validate the PSS padded CRLs and OCSP Responses. Although the signatures are valid.

I have attached both CRL (PSS padded) and OCSP (PSS padded) PAdES LTV documents. Your help will be appreciated.

How can I upload the signed documents for reference?
