上述过程使得public key authentication方式和单纯密码认证方式显得有些不是很方便:每次你登陆服务器,替代输入一个简单密码的方式,而必须输入一个很长的passphrase。一个解决方案是你使用一个authentication agent,该认证代理就是一个保存拥有已经被解密过的私钥并且据此在被请求时创建签名。Putty的认证代理被称为Pageant....
The private key is private.Public key authentication never transmits the private key to the server. Even if the remote server is compromised, the attacker cannot access the private key stored on the local machine. Multi-factor authentication.Adding a passphrase to the private key acts as an ad...

Private key Authentication algorithm When you use your public key to encrypt something, only your private key can decrypt it. To enable encrypted communication between machines, you would retain your private key on your workstation and share your public key with the remote machines you’d like to...
