Java & PHP & Javascript 通用 RSA 加密 解密 (长字符串)

2019年11月06日 阅读数:72
这篇文章主要向大家介绍Java & PHP & Javascript 通用 RSA 加密 解密 (长字符串),主要内容包括基础应用、实用技巧、原理机制等方面,希望对大家有所帮助。

系统与系统的数据交互中,有些敏感数据是不能直接明文传输的,因此在发送数据以前要进行加密,在接收到数据时进行解密处理;然而因为系统与系统之间的开发语言不一样。php

本次需求是生成二维码是经过java生成,由php来解密。基于这类需求因此选择了RSA进行加解密。html

生成RSA公私钥分红三步生成,第一、2步能够知足php的使用,因为java的私钥要转化为PKCS8格式才能使用,因此执行第3步来实现。java

还有一种加密方式参考: DES ECB 模式 JAVA PHP C# 实现 加密 解密 兼容 。git

 

一、生成私钥github

openssl genrsa -out rsa_private_key.pem 1024 

以下:算法

-----BEGIN RSA PRIVATE KEY-----
MIICXQIBAAKBgQC6BSDlbRplhMMNZBKHX4xe8AwESpzHVfAcHHsX9FFSMuF91W3c

-----END RSA PRIVATE KEY-----

 

二、生成公钥apache

openssl rsa -in rsa_private_key.pem -pubout -out rsa_public_key.pem

以下:json

-----BEGIN PUBLIC KEY-----
MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC6BSDlbRplhMMNZBKHX4xe8AwE
SpzHVfAcHHsX9FFSMuF91W3cxgT/g5n+qlLLFzCE3hWG/yX5NMAxR4mS3MlhyXKw

qvOw3G9leClSvjVnSwIDAQAB
-----END PUBLIC KEY-----

 

三、将RSA私钥转换成PKCS8格式api

openssl pkcs8 -topk8 -inform PEM -in rsa_private_key.pem -outform PEM -nocrypt > java_rsa_private_key.pem

以下:app

-----BEGIN PRIVATE KEY-----
MIICdwIBADANBgkqhkiG9w0BAQEFAASCAmEwggJdAgEAAoGBALoFIOVtGmWEww1k
