Environment variable for certificate key size
NetBackup uses security certificates to authenticate NetBackup hosts for secure communication. The security certificates conform to the X.509 Public Key Infrastructure (PKI) standard. A NetBackup primary server acts as the certificate authority (CA) and issues digital certificates to hosts. NetBackup supports the following certificate key sizes: 2048 bits, 4096 bits, and 8192 bits.
To use a certificate key size larger than 2048 bits, set the NB_KEYSIZE environment variable on the primary server before you start the installation.
For example:
NB_KEYSIZE = 4096
The NB_KEYSIZE can only have the following values: 2048, 4096, and 8192.
Caution:
You should carefully choose the key size for your environment. Choosing a large key size may reduce performance. You should consider all factors to determine the correct key size for your environment.
