通常我们再批量配置多台机器的时候经常出现通过ssh批量登录机器提示 RSA key fingerprint is ::a6:b1:c9:d7:b8::c1:::8e:f5::2b:8b. Are you sure you want to continue connecting (yes/no)? 这样导致我们批量操作机器非常不方便,这样我们就需要取消这个提示,直接到输入密码的部分. 解决办法很简单,修改/etc/ssh/ssh_config 找到这一行 # StrictHostKeyChecki…

基于非对称算法的RSA Key主要有两个用途,数字签名和验证(私钥签名,公钥验证),以及非对称加解密(公钥加密,私钥解密).本文提供一个基于OpenSSL和Python进行非对称加解密的例子. 1. OpenSSL实现非对称加解密1.1 生成私钥,并导出公钥生成2048 bit的PEM格式的RSA Key:Key.pem $ openssl genrsa -out Key.pem -f4 2048Generating RSA private key, 2048 bit long modulus.…
