Hi Andy: If you use the OpenSSL CA scripts as shipped and documented both in the OpenSSL document, the book, or numerous places on the web, they already use "index.txt" as a list of all issued certificates. So no extra work is needed. Have fun. Patrick. On 2010-09-22, at 4:52 PM, Andy GOKTAS

So using the "-CAserial serial.srl" might be a good idea to avoid this. Now this leads me to the next question: - Besides manually documenting a cross-reference for each certificate that I sign to a serial number, is there any way to have this scripted and for an appending log to the serial

The serial number has to be unique for the issuer (CA). You can have multiple certificates with the same SubjectName, but the SerialNumber field has to be unique unless you're using a different issuer. Chris On Sun, Sep 19, 2010 at 10:53 PM, wrote: > If you generate multiple certs with the sam

If you generate multiple certs with the same serial number, Firefox (and anything built with NSS) will absolutely refuse to have anything to do with those sites. There's no "click 3 times to get access", it's a simple refusal to talk with a non-standards-compliant server. (Of course, this put

2010-09-17 Thread Andy GOKTAS
Hello, Just curious if anyone knows, but what happens if I generate multiple server certs (using my self generated signing CA using openssl) that have the same assigned serial number? Does this create a conflict within the network and if users's end up accessing both certs, kabm? Is
