Determines the size of the host key when you enable the SSH v1 protocol. The size of the host key can range from 384 to 2,048 bits and must differ from the size of the server key by 128 bits. The default host key strength is 768 bits.
The larger the size the greater the security, but the longer it takes to initiate a new SecureAdmin session and the higher the likelihood of decreasing filer performance.
