RSA example

First, we're going to generate our key, confirming the default location in which to save the key, and providing a passphrase when prompted:

$ ssh-keygen -b 4096 -C "Example RSA Key"Generating public/private rsa key pair.Enter file in which to save the key (/home/vagrant/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/vagrant/.ssh/id_rsa.Your public key has been saved in /home/vagrant/.ssh/id_rsa.pub.The key fingerprint is:SHA256:hAUNhTqXtfnBOkXMuIpxkvtTkM6NYRYxRbT5QWSVbOk Example RSA KeyThe key's randomart image is:+---[RSA 4096]----+|      =@*=+o.o   ||      o++=+ =    ||     o.=+*.o     ||    * X.+.+.E    ||     & *S+..     ||    o = = .      ||     . . .       ||      o          ||       .         |+----[SHA256]-----+
