The original signature algorithm supported only ssh-rsa. That signature used SHA-1. The hash algorithm SHA-1 is considered weak/broken today, so SHA-1 was replaced with SHA-2. The SSH key types rsa-sha2-256 and rsa-sha2-512 replaced ssh-rsa. The OpenSSH server disabled the ssh-rsa ...

客户端报错:Putty软件报错Couldn't agree a host key algorithm (available: rsa-sha2-512,rsa-sha2-256)通常是因为Putty无法选择与远程主机协商一致的主机秘钥算法。解决此问题有如下两种方式: 修改客户端。 打开Putty,进入“SSH”选项卡。 在“SSH”选项卡下的“Kex”部分中,将“Preferred SSH protocol version...
