No, it is because it cannot find the certificate that Symantec used to sign the response, specifically the certificate with Subject name "/C=US/O=Symantec Corporation/OU=Symantec Trust Network/CN=Symantec SHA256 TimeStamping Signer - G1". I am kind of disappointed in how little detail is included in the output from ts -reply -text, I expected it to output all the fields, similar to what other openssl commands do when passed the -text option. So I guess the next step would be to dump SHA.sha.tsr using Peter Gutmann's dumpasn1.c program, something like openssl base64 -d -in SHA.sha.tsr -out SHA.sha.tsr.bin dumpasn1 -v SHA.sha.tsr.bin Enjoy Jakob -- Jakob Bohm, CIO, Partner, WiseMo A/S. https://www.wisemo.com Transformervej 29, 2860 S?borg, Denmark.
