Chapter 2 Generating Certificates
Generating Certificates with OpenSSL
export OPENSSL_CONF /opts/open/openssl.cnf
• Specifying the –config option on the command line
openssl <additional parameters> config ./openssl.cnf
The CA and CA_Default sections of the openssl.cnf file are particularly important because they specify
information related to the configuration of a CA. Figure 2-1 shows an example of an openssl.cnf file,
from the OpenSSL distribution.
