Openssl steps to create a 2048 bit key length to be used with Juniper

Problem:

You do not have the option to create a 2048 bit length CSR from your Juniper management interface.  This mostly affects Juniper systems 6.x - 6.4

Here is the Solution:

There are 2 options

Option 1: Use OpenSSL command

Generate a key pair, and go to "Configuration -> Certificates -> Device Certificates -> Import Certificate and Key" and import the key file and certificate file (these are stored separately)

Use the CSR to submit your request to Entrust and when the certificate is signed and sent back, import the certificate and key as mentioned above.

An example of the OpenSSL command is:

openssl genrsa -des3 -out "C:\temp\private_key.key" 2048
openssl req -new -key "C:\temp\private_key.key" -out "C:\temp\Entrust.csr"

Option 2: Upgrade Juniper
