Your public key has been saved in /home/stk/.ssh/id_rsa.pub. The key fingerprint is: 1c:fb:fa:f1:f7:f4:13:62:79:8e:57:45:b8:52:cb:a0 stk@pchero21.com The key's randomart image is: +--[ RSA 2048]----+ | oo | | .. o. | | =.o+.o | | o.X.o+ | | S X. | | * + | | . o | | . | | | +-----------------+
키 생성 이후, ~/.ssh 디렉토리를 확인하면 생성된 key 내용들을 볼 수 있다.
$ cd ~/.ssh $ ls -tlr total 16 -rw-------. 1 stk stk 397 Oct 29 2015 authorized_keys -rw-r--r--. 1 stk stk 668 May 11 10:27 known_hosts -rw-r--r--. 1 stk stk 416 May 11 11:01 id_rsa.pub -rw-------. 1 stk stk 1675 May 11 11:01 id_rsa
