一个适用于微信小程序的RSA签名库。

RSA签名的小程序DEMO：https://github.com/zhangzhaopds/WeixinApp_RSA_Signature.git

使用

1、引入文件

var RSA = require('../../utils/wx_rsa_signature.js')

需要注意的是：区分RSA私钥的类型，有pkcs1和pkcs8。pkcs8格式的私钥主要用于Java中。

// pkcs1格式： -----BEGIN RSA PRIVATE KEY----- -----END RSA PRIVATE KEY------ // pkcs8格式： -----BEGIN PRIVATE KEY----- -----END PRIVATE KEY-----
