Hi: I guess I"m not sure what is going on here.
The setting you describe sounds like it determines that we do a check if the certificate you are checking has an AIA extension. This appears to be the case in your scenario. The setting you chose to work around the problem merely ignores bad checks. There still appears to be some issue when you have it set to "2", where Adobe doesn't like the OCSP cert itself. I assume this is Windows, so you might go into the "Internet" config options and look at the certs to see if the OCSP cert chain is fully trusted. This is just a guess of course. ----- Original Message ----- From: "Alexander" <ricardoalx.pe...@gmail.com> To: pki-users@redhat.com Sent: Wednesday, September 21, 2016 10:04:34 AM Subject: Re: [Pki-users] Pki-users Digest, Vol 101, Issue 4 Hi John, thanks for answering... Yes it is, My CA it's trusted by the Adobe Application. I solved it partially, but I think the problem is with the certificate of the OCSP. Solution: 1. Enable LOG for Abode Acrobat or Adobe Reader to see more details of the error. Check this info: http://www.adobe.com/content/dam/Adobe/en/devnet/reader/pdfs/acrobat_reader_security_9x.pdf Page 127 5.3.4.4 Validation Certificate Data Logging Example 5.7: Chain building log file settings [HKEY_CURRENT_USER\Software\Adobe\Adobe Acrobat\8.0\Security\cASPKI\cAdobe_ChainBuilder] "ILogLevel" = dword: 00000008 "SLogFilePath" = <BINARY path to Existing directory for log file> The folder path has to exist, but Acrobat will create the file if it's missing. For example, if you want to save the file to C:\LogFile\digSigLog.txt the folder LogFile would have to exist on the C drive, but the log file itself will get created if it's not there already. When you type in the file path and name in the Edit Binary Value dialog in regedit, make sure you null terminate the string by typing a zero at the end of the hex data on the left side of the dialog. It will look like a dot on the right side, but it's not really a dot (a dot is 2E in hex). 2.- Signature Validation RevCheck http://www.adobe.com/devnet-docs/acrobatetk/tools/PrefRef/Windows/Security.html#SignatureValidationRevCheck%28OCSP%29 [HKEY_CURRENT_USER\Software\Adobe\Adobe Acrobat\8.0\Security\cASPKI\cAdobe_OCSPRevChecker] "iReqRevCheck" = dword: 1 iReqRevCheck: Indicates whether revocation checks are required to succeed on the OCSP response. Set this value to 1 (1: Do a check IF certificate has AIA extension or responder info is in registry; don't fail if the check fails.) After setting these values in the registry, I indicated that the signatures are valid. If I leave the default value of 2 (2: Do you have to check IF AIA certificate extension or respond info is in registry, all checks must succeed if there is data and to check OCCURS.) Continued to receive the same error message So I think the key to solve completely the problem is: The OCSP certificate or certificates used to sign must have: Authority Information Access (AIA) certificate extension or respond info is in registry. Really do not know how this or how to verify that the certificates comply with this requirement. 2016-09-21 11:00 GMT-05:00 < pki-users-requ...@redhat.com > : Send Pki-users mailing list submissions to pki-users@redhat.com To subscribe or unsubscribe via the World Wide Web, visit https://www.redhat.com/mailman/listinfo/pki-users or, via email, send a message with subject or body 'help' to pki-users-requ...@redhat.com You can reach the person managing the list at pki-users-ow...@redhat.com When replying, please edit your Subject line so it is more specific than "Re: Contents of Pki-users digest..."
