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...
在SSH公钥认证中,RSA_SHA2_512和RSA_SHA2_256是两种不同的签名算法。它们的主要区别在于所使用的哈希函数(SHA-512或SHA-256)和生成的签名大小。SHA-512提供了更高的安全性,因为它生成的哈希值更长,更难被破解。然而,SHA-256在处理速度上可能更快,并且对于大多数应用来说也是足够安全的。 RSA_SHA2_512:使用...

将SSH 客户端更新为支持 sha2-256 和 sha2-512 算法的版本。
FATAL ERROR: Couldn't agree a host key algorithm (available: rsa-sha2-512,rsa-sha2-256),解决方法:将SSH客户端更新为支持sha2-256和sha2-512算法的版本。
OpenSSH migrated the ssh-rsa key type, which historically used the ssh-rsa signature algorithm based on SHA-1, to the new rsa-sha2-256 and rsa-sha2-512 signature algorithms. x/crypto/ssh was not ready for the key type / signature algorithm mismatch, so it needs a few changes. More...
Compiled and linked curl to libssh2 current github master dev branch in order to get rsa-sha2-256 and rsa-sha2-512 server-key-exchange methods. First SSH server connect works fine, server key gets saved to ssh local keyfile. Subsequent c...
