Example: Creating A Private Key File And Certificate - ZyXEL Communications NSA-2400 User Manual

8.4.4 Example: Creating a Private Key File and Certificate

This example is for Windows users. Linux users may use the openssl package which can
perform the same function.
Links and commands are given as an example only and are correct at the time
of writing. They may be liable to change without notice.
1 Download http://www.slproweb.com/download/Win32OpenSSL_Light-0_9_8g.exe.
This will install an openssl.exe file which you can execute at the command prompt in
Windows. The default location is C:\OpenSSL\bin\openssl.exe.
2 Click Start > Run, and then type C:\OpenSSL\bin\openssl.exe. (Do not open
the Windows command prompt and navigate to C:\openssl\bin to execute openssl.exe.)
3 A command prompt window should appear displaying openSSL> as the prompt.
4 Enter this command at the command prompt:
openSSL>req -new -x509 -nodes -keyout myssl.key -out
myssl.csr
5 Now you are requested to enter some personal information to associate your
identification with the SSL Key. Note for the Common Name, you must type your
NSA's Fully Qualified Domain Name (FQDN). For example, if your NSA-2400's
domain name is nsa.zyxel.com then make sure the common name is exactly the
same. This is important as otherwise your certificate will have a domain name mismatch.
OpenSSL> req -new -x509 -nodes -keyout myssl.key -out myssl.csr
