Create a Root Certificate and Server Certificates
Summary
Use this procedure if your company or agency does not have its own Certificate
Authority and you do not want to use a commercial Certificate Authority to sign
your server certificates.
• Create a CA root certificate that will sign all server certificates to be used with Rack
PDU. During this task, two files are created:
– The file with the
.p15 suffix is an encrypted file that contains the Certificate
Authority’s private key and public root certificate. This file signs server certificates.
– The file with the .crt suffix contains only the Certificate Authority’s public root
certificate. Load this file into each Web browser that will be used to access the
Rack PDU so that the browser can validate the server certificate of that Rack PDU.
• Create a server certificate, which is stored in a file with a . p15 suffix. During this task,
you are prompted for the CA root certificate that signs the server certificate.
• Load the server certificate onto the Rack PDU.
• For each Rack PDU that requires a server certificate, repeat the tasks that create and
load the server certificate.
Define the size of the public RSA key that is part of the certificate generated
by the Rack PDU Security Wizard.You can generate a 1024-bit key, or you
can generate a 2048-bit key, which provides complex encryption and a higher
level of security. (The default key generated by the Rack PDU, if you do not
use the Wizard, is 2048 bits.)
