API接口-RSA加密算法

PS：我是翻阅了网上大部分资料，进行整合，得出以下文章。（不是原创，只是进行了整合，方便理解。）

1.什么是RSA加密

RSA （详见维基百科）算法是现今使用最广泛的公钥密码算法，也是号称地球上最安全的加密算法，与 md5 和 sha1 不同，到目前为止，也只有极短的RSA加密被**。
那么什么是公匙密码算法呢，根据**的使用方法，可以将密码分为对称密码和公钥密码，接下来我们来简单说明下它们两个。

对称密码：加密和解密使用同一种**的方式，常用的算法有 DES 以及 AES。
公钥密码：加密和解密使用不同的密码的方式，因此公钥密码通常也称为非对称密码，常用的算法有 RSA。

由于本文讨论的是 php 的 RSA 加密实例，这里就不详细说明了，对于 RSA 算法有兴趣的朋友可以查看下面的文章

《带你彻底理解RSA算法原理》

对于 php 更多加密方式有兴趣的朋友可以查看下面的文章

《PHP数据加密技术与**安全管理》

2.使用场景

  • 为移动端（IOS，安卓）编写 API 接口
  • 进行支付、真实信息验证等安全性需求较高的通信
  • 与其他第三方或合作伙伴进行重要的数据传输

3.前端和后端代码

大家可以先到http://web.chacuo.net/netrsakeypair这个网站，在线生成公钥和私钥

4.补充

如果是多个端（一对多），可以多生成几对私钥和公钥。

  • pubkey_server、prikey_server（服务端）
  • pubkey_client、prikey_client（客户端）
  • pubkey_ios、prikey_ios（IOS端）

最后说一句

最后要说明的是，公钥、私钥都可以加密，也都可以解密。其中：用公钥加密需要私钥解密，称为“加密”。由于私钥是不公开的，确保了内容的保密，没有私钥无法获得内容；用私钥加密需要公钥解密，称为“签名”。由于公钥是公开的，任何人都可以解密内容，但只能用发布者的公钥解密，验证了内容是该发布者发出的。
