Generating CA Certificates
Generating CA certificates requires access to an OpenSSL system. You can obtain a Windows version at
http://gnuwin32.sourceforge.net/packages/openssl.htm.
The files that are created during this process are stored in the /bin directory of the OpenSSL program.
To generate CA certificates, do the following:
Double-click openssl.exe in the directory.
Step 1
Step 2 Create the key using the OpenSSL application. Enter the following command:
OpenSSL> genrsa -out rt.key 1024
Loading 'screen' into random state - done
Generating RSA private key, 1024 bit long modulus
.++++++
.......++++++
e is 65537 (0x10001)
Step 3 Set how long the certificate will be valid. Keep track of this date.
Use a different common name for the client and server certificates.
Note
OpenSSL> req -new -key rt.key -x509 -days 365 -out rt.cert
You are about to be asked to enter information that will be incorporated into your
certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [AU]:
State or Province Name (full name) [Some-State]:
Locality Name (eg, city) []:
Organization Name (eg, company) [Internet Widgits Pty Ltd]:
Organizational Unit Name (eg, section) []:
Common Name (eg, YOUR name) []:home
Email Address []:
Step 4 Create the proper pkcs12 certificate. The export password is the password needed by the Cisco SME
RSA installation.
OpenSSL> pkcs12 -export -in rt.cert -inkey rt.key -out rt.p12
Loading 'screen' into random state - done
Enter Export Password:
Verifying - Enter Export Password:
Step 5 Generate a new key for the client.
OpenSSL> genrsa -out client.key 1024
Loading 'screen' into random state - done
Generating RSA private key, 1024 bit long modulus
..................++++++
....++++++
e is 65537 (0x10001)
Create the client.csr file. This is the owner. The common name must be different from the issuer home.
