-b “Bits” This feature specifies the quantity of bits in the key. The laws that govern the use scenario for SSH may well call for a certain important length to be used. Generally, 2048 bits is looked upon as ample for RSA keys.
Because the personal critical isn't subjected to the network which is shielded through file permissions, this file must under no circumstances be obtainable to anyone apart from you (and the root user). The passphrase serves as an extra layer of safety in the event these ailments are compromised.
