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 master server acts as the certificate authority (CA) and issues digital certificates to hosts. NetBackup now supports the following certificate key sizes: 2048 bits, 4096 bits, 8192 bits, and 16384 bits.
With a NetBackup 9.1 installation, new root CA with 2048 bits key strength is deployed. To use a certificate key size larger than 2048 bits, set the NB_KEYSIZE environment variable on the master server before you start the installation.
For example:
NB_KEYSIZE = 4096
The NB_KEYSIZE can only have the following values: 2048, 4096, 8192, and 16384.
For more information about CA migration and certificate key sizes, see the NetBackup Security and Encryption Guide.
