"OpenSSL" Acting as a CA (Certificate Authority)
This section provides a tutorial example on how to prepare OpenSSL to be used as CA (Certificate Authority) to sign other people's CSR (Certificate Signing Request).
If I want to act as a CA (Certificate Authority), I must have a tool
to sign other people's CSR (Certificate Signing Request). As we learned from
previous chapters, "keytool" can not sign CSR. So I must use "OpenSSL"
to act as a CA.
Here is a list of things I need to do with "OpenSSL" as a CA:
- Install "OpenSSL" installed properly and create configuration file, openssl.cnf.
- Created a CA private key file with 2048-bit keys, and protect it with a password.
- Self-sign my CA public key certificate, which can be given out to anyone.
Let's check the "OpenSSL" installation first. If "OpenSSL" was installed at \local\GnuWin32\,
the following command should report back the version number:
OpenSSL 0.9.7c 30 Sep 2003
To save typing time, I added \local\gnuwin32\bin\ to the PATH environment variable as shown above.
Then look at the configuration file, openssl.cnf, which is needed only when I self-signing my CA public certificate.
I can use the openssl.cnf as is without any changes. But if I want to put in my CA distinguished name information
to save time when self-signing my CA public certificate, I can add these settings to openssl.cnf:
countryName_default = CA
stateOrProvinceName_default = HY State
localityName_default = HY City
0.organizationName_default = HY Company
organizationalUnitName_default = HY Unit
commonName_default = Herong Yang
emailAddress_default = herongyang.com
So I am ready to generated my CA private key as described in the next section.
