使用"SSH2 PUBLIC KEY"中的公共密钥来验证JSch中的主机密钥.格式(RFC 4716) [英] Verify host key in JSch with public key in "SSH2 PUBLIC KEY" format (RFC 4716)

问题描述

当尝试使用以下命令验证主机密钥时，我遇到了UnknownHostKey: servername问题:

I am facing a problem with UnknownHostKey: servername, when trying to verify the host key using:

jsch.setKnownHosts("target/hostname_keys");

是否可以使用如下所示的SSH2格式的主机密钥文件

Is it possible to use hostkey file in SSH2 format that looks like this

---- BEGIN SSH2 PUBLIC KEY ----
AAAAB3NzaC1kc3MAAACBAKKQ7hwq7
.....
w5Uw==
---- END SSH2 PUBLIC KEY ----

使用JSch?

是否有一些可以使用SSH2密钥的良好库?

Is there some good libraries that can work with SSH2 keys?

推荐答案

JSch不支持这种格式的公共密钥.

JSch does not support public keys in this format.

但是很容易将其转换为known_hosts格式.

But it's easy to convert that to known_hosts format.

基本上，只需将这两行合并为一个，并添加一个主机名即可:

Basically, just merge the lines into one and prepend a hostname:

example.com AAAAB3NzaC1kc3MAAACBAKKQ7hwq7...w5Uw==
