I'm planning to run openssl ocsp in server mode, openssl ocsp \ -index /svr/demoCA/index.txt \ -port 8888 \ -CA /svr/demoCA/certs/CA/CA.cert.pem \ -rsigner /svr/demoCA/crl/OCSP.cert.pem \ -rkey /svr/demoCA/crl/OCSP.privkey.pem \ -text -out /var/log/ocsp.log
where "OCSP.cert.pem" is a single-purpose cert, only for the OCSP responder. What's the MINIMAL (Extended)KeyUsage for the cert? Currently, I have cat /svr/demoCA/crl/OCSP.cert.pem | grep -i usage -A1 X509v3 Extended Key Usage: OCSPsigning -- X509v3 Key Usage: critical Digital Signature, Non Repudiation, Key Encipherment Obviously, the "OCSPsigning" Extended usage is required. Which, if any/all, of the "Digital Signature, Non Repudiation, Key Encipherment" KeyUsage specifications are required, if this cert will be used ONLY for/by the OCSP responder daemon? Thanks. ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org
