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.
For more information about CA migration and certificate key sizes, see the NetBackup Security and Encryption Guide.
