Create a Private Key. Here -new denotes a new keypair, -newkey rsa:2048 specifies the size and type of your private key: RSA 2048-bit, -keyout dictates where they new private key will go, -out determines where the request will go, and -config tells openssl to use our config rather than the default config..

This is particularly useful on low-entropy systems (i.e., embedded devices) that make frequent SSL invocations. 4.2.2  PKI creation. CRL number file. OpenSSL is somewhat quirky about how it handles this file. Also, if something goes wrong, you’ll probably have a much harder time figuring out why. # # Establish working directory. 4) Make a custom config file for openssl to use. In the method, attackers needed to predict the serial number of X.509 certificates generated by CAs besides constructing the collision pairs of MD5. Up RAND_BITS to 159, and comment why: now confirms to CABForum guidelines (Ballot 164) as well as IETF RFC 5280 (PKIX).

Now we need to copy the serial file over, for certificate serial numbers:copy d:\openssl-win32\bin\pem\democa\serial d:\openssl-win32\bin\democa Lastly, we need an empty index.txt file. You are getting the "variable lookup failed for ca::serial" error, because OpenSSL "ca" command can not find the required "serial" option in the configuration file.
