首先介紹背景：有一php項(xiàng)目，只提供了php加解密接口,因業(yè)務(wù)需求，需要提供python版本加密接口。
注意：
1、加密方式：使用Crypto包，RSA/1024bit KEY，實(shí)例加密使用公鑰加密，私鑰解密，反過(guò)來(lái)原理一樣
2、加密填充方式：OPENSSL_PKCS1_PADDING
3、python3? PKCS1_v1_5.new.encrypt 只接受byte數(shù)據(jù)
4、切割加密解密，原因自行百度，可參考：https://blog.csdn.net/orangleliu/article/details/72964948
php代碼如下：
//請(qǐng)求內(nèi)容結(jié)構(gòu)體
$data=array(
? ? ? ? "fromname"=>"告警",
? ? ? ? "html"=>"恢復(fù), 服務(wù)器: 192.168.2.111 utilization more than 90% bj,故障:IO 已恢復(fù)!",
? ? ? ? "mail"=>"XXXX@qq.com",
? ? ? ? "subject"=>"現(xiàn)網(wǎng)警告，請(qǐng)盡快處理"
? ? ? ? );
//通訊密鑰公鑰

//utf-8編碼 json 格式化

//base64 和urlencode 加密
$data=urlencode(base64_encode($encrypted));
