Specifies the modulus size of the key pair(s): For RSA, the valid values are 360, 512, 768, 1024, and 2048. For DSA, the valid value is fixed as 1024. For SSH version 2, the minimum recommended key size is 768 bits. A key size with a larger number provides higher security but takes longer to generate. This object cannot be modified while this row is active, unless the associated dSshCryptoKeyPairReplace object is set to True in the same Set PDU.
