![ssh认证输出含义:类型1](https://linux22.com/image/149107/ssh%E8%AE%A4%E8%AF%81%E8%BE%93%E5%87%BA%E5%90%AB%E4%B9%89%EF%BC%9A%E7%B1%BB%E5%9E%8B1.png)
我尝试使用私钥通过 ssh 连接到远程服务器,我看到输出的一部分:
debug1: identity file /home/gigi/.ssh/id_rsa type 1
这是什么type 1
意思?
答案1
(open)ssh 客户端有几个列表关键类型:
/* Key types */
enum sshkey_types {
KEY_RSA,
KEY_DSA,
KEY_ECDSA,
KEY_ED25519,
KEY_RSA_CERT,
KEY_DSA_CERT,
KEY_ECDSA_CERT,
KEY_ED25519_CERT,
KEY_XMSS,
KEY_XMSS_CERT,
KEY_UNSPEC
};
这些类型在sshkey.c代码设置keytypes
结构时;它们是type
该结构中的值。要获取相应的名称,请从上述序列中获取键类型,使用其值(从 1 开始)并找到相应的name
或shortname
。手动对它们进行插值(并按 排序type
)给出下表,其中包含键名称、短名称和类型:
NULL, NULL, -1
rsa-sha2-256, RSA, 1
rsa-sha2-512, RSA, 1
ssh-rsa, RSA, 1
ssh-dss, DSA, 2
ecdsa-sha2-nistp256, ECDSA, 3
ecdsa-sha2-nistp384, ECDSA, 3
ecdsa-sha2-nistp521, ECDSA, 3
ssh-ed25519, ED25519, 4
