一个简单的api来执行基本的基于rsa的操作。
simple-rsa的Python项目详细描述
简单rsa
A straightforward API to perform basic RSA-based operations.
基本原理
任何加密库都会公开所有的可能性，而且应该公开。但有时您只需要一个简单的sign和validateapi。这就是密码模块周围的包装器模块。没有更多，没有更少。
开始
该模块基本上公开了以下功能：
generate_key_pair()返回私钥和公钥的元组encode(key)返回编码密钥decode(pem)返回键sign(payload, key)返回签名validate(payload, signature, key)返回true或异常
