ssh-keygen
秘密鍵の作り方
# 新方式
$ ssh-keygen -t rsa -f id_rsa Generating public/private rsa key pair. Enter passphrase (empty for no passphrase) Enter same passphrase again: Your identification has been saved in id_rsa. Your public key has been saved in id_rsa.pub. ...
# 旧方式
$ ssh-keygen -t rsa -m PEM -f id_rsa ...
公開鍵の作り方
# RFC4716/SSH2形式
$ ssh-keygen -e [-m rfc4716] -f id_rsa ---- BEGIN SSH2 PUBLIC KEY ---- Comment: "1024-bit RSA, converted by user@slackware.local from OpenSSH" AAAAB3N.......................... ........ ---- END SSH2 PUBLIC KEY ----
# PEM PKCS8形式
$ ssh-keygen -e -m pkcs8 -f id_rsa -----BEGIN PUBLIC KEY----- MIGdMA0.......................... ........ -----END PUBLIC KEY-----
# PEM形式
$ ssh-keygen -e -m PEM -f id_rsa -----BEGIN RSA PUBLIC KEY----- MIGHAoG......................... .......... -----END RSA PUBLIC KEY-----
# OpenSSH(authorized_keys)形式
$ ssh-keygen -i -f <(ssh-keygen -e -f id_rsa) ssh-rsa AAAAB3Nz....................
