首先,需要确认是密钥交换算法(Key Exchange Algorithms)不匹配,还是主机密钥算法(Host Key Algorithms)不匹配。错误信息通常会给出提示,例如: “Error: Failed to initialize the client because the key-exchange algorithm does not match.” 表示密钥交换算法不匹

密钥交换(Key Exchange)是SSH中紧接着的第二步,它最直接的目的有两个:用一个安全的方式将接下来的packet加密密钥传到双方手中、让客户端相信“同时获得密钥的另一个人”就是千真万确的服务器。 第一步,客户端在payload中表明Message Code = 20(Key Exchange Init),并毫无保留的把自己支持的各种加密...
