Setting the required key strength before installation or upgrade using the NB_KEYSIZE environment variable
After NetBackup 8.3 installation or upgrade, by default a new root CA with 2048-bits key strength is deployed. If you want a larger key strength, you can set an environment variable to a value larger than 2048 bits before installation or upgrade.
To have a NetBackup CA with a key strength larger than 2048 bits
- Set the NB_KEYSIZE environment variable on the master server before you start NetBackup installation or upgrade.
For example: NB_KEYSIZE = 4096
The NB_KEYSIZE can only have the following values: 2048, 4096, 8192, or 16384.
- Install or upgrade NetBackup on hosts.
In case of upgrade, continue with the CA migration.
