验证
支持下列验证方法：- 密码
用户名/密码和键盘交互验证。同时支持服务器密码更改请求。 - 公钥
密钥文件（PuTTY、VanDyke's SecureCRT、SSH.com、OpenSSH、PEM）、X.509 证书、来源于证书储存或智能卡的 Microsoft Windows 证书（PKCS #11）。 - Kerberos v5（GSSAPI/SSPI）
支持 Microsoft Windows Kerberos（SSPI）和 MIT Kerberos（GSSAPI）实现。 - 基于主机的
使用主机密钥文件或证书的验证 - RSA SecurID
RSA SecurID 双因素身份验证。
