RSA was first publicly described in 1977 by Ron Rivest, Adi Shamir and Leonard Adleman of the Massachusetts Institute of Technology. British mathematician Clifford Cocks created a public key algorithm in 1973 that was kept classified by the U.K. Government Communications Headquarters intelligence and ...

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 ...
