Public key authentication is a cornerstone of internet security. Having a public:private key pair is the prerequisite for using public key authentication.
In Linux, you can generate a good keypair simply by typing: ssh-keygen
However, it is probably a good idea to do one of the following:
- use a large number of bits with the rsa algorithm by typing:
ssh-keygen -t rsa -b 4096 - use the newest algorithm by typing:
ssh-keygen -t ed25519
