RSA加密 解密 加签 验签
/**
* 注：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----- */
1. 将 wx_rsa.js文件copy到自己想放置的目录下，并在需要用到的js文件中引用 如：
var RSA = require('../../utils/wx_rsa.js')
//获取应用实例
var app = getApp()
var Sig = ""
var encStr =""
2. 在对应的触发事件下进行相应的操作：
var privateKey = '-----BEGIN RSA PRIVATE KEY-----MIICXgIBAAKBgQCoChRDJ6e7BTE5yYBIS + NGYBpDs7ftEematqhvMmOFcJng7qjJk + yJ1j7DCqbCD2f / BI6gTfGXASiYuO6kklZu8Pkw4HAUkaaGyhaC8Z + TMg79PPRz5hziEdFXPTdXvXudiXbI2Wi6D90ZaSwN6ZHs7Mtc5VgGK3jxS35iLm+ oAQIDAQABAoGBAI + nHi9SxUdSZwS5yBsGFSNioNFj4Eag243RvShicUXwPvxVyqGY / cvQBhODFZAsz4Dpimxsda3b5bK51fmGyK / nXraHRunWcG7cDDB0EnRpGh4LvMI5Tny + kV0v07N0kkYF+ Lig88IjyBXMAY8m97QK / Huf6MsDFo7B6maSvlmBAkEA35GXk6achryGAoUyyLSro7bI9A9 + wXWFdXoqu1 / X1sZ8taGy7saB + XEA6EQ + XHRp7rZkQ5StoBL +reDGvLJLWQJBAMBqW / F + qg1VpmV / EfYTSS0 + jliw / Ik4kKHLuD / bYK61FG80JIoxLbelB / 1ZVZ8WR0cUKgrmoo8HOggjocNTNOkCQQCYibK86CHGAF0C3TSgIj01r2H+u4 / FmVScqeT8AVG31aeDGbeHGOPXeJWg4 + cUl80rNUDFp2yrWipwInwWhSPJAkAf+ 02u9Ru0vbC7nARTP19hWs10Jm7DLBi2G9NTIdaPE2ADH8qXAZeUt6R9UrTtjVlpkgtu5mjMlynpImsHuTPJAkEAoU10QspqfxL4F44KdHjHY1btc8wb4soaLy / eAY8PLE + jpNh8jsqA8v1EqLQbYz50D / BpkJsT5W + wydTvtEE3sA ==-----END RSA PRIVATE KEY-----'

加密：
jiami: function () {
var input_rsa = this.data.input;
var encrypt_rsa = new RSA.RSAKey();
encrypt_rsa = RSA.KEYUTIL.getKey(publicKey);
console.log('加密RSA:')
console.log(encrypt_rsa)
encStr = encrypt_rsa.encrypt(input_rsa)
encStr = RSA.hex2b64(encStr);
console.log("加密结果：" + encStr)
this.setData({
output: encStr
})
},
解密：
jiemi: function () {
var decrypt_rsa = new RSA.RSAKey();
decrypt_rsa = RSA.KEYUTIL.getKey(privateKey);
console.log('解密RSA:')
console.log(decrypt_rsa)
console.log(encStr+"00--00")
if (encStr.length <=){
wx.showToast({
title: '请先加密',
icon: 'loading',
duration:
})
}else{
encStr = RSA.b64tohex(encStr);
console.log(encStr + "001--100")
var decStr = decrypt_rsa.decrypt(encStr)
console.log("解密结果：" + decStr)
this.setData({
output: decStr
})
}
},
加签：
jiaqian: function () {
console.log('加签RSA1:')
var sign_rsa = new RSA.RSAKey();
sign_rsa = RSA.KEYUTIL.getKey(privateKey);
console.log('加签RSA:')
console.log(sign_rsa)
var hashAlg = 'sha1';
Sig = sign_rsa.signString("signData", hashAlg);
Sig = RSA.hex2b64(Sig); // hex 转 b64
console.log("加签结果：" + Sig)
this.setData({
output: Sig
})
},
验签：
yanqian: function () {
var verify_rsa = new RSA.RSAKey();
verify_rsa = RSA.KEYUTIL.getKey(publicKey);
console.log('验签RSA:')
console.log(verify_rsa)
if (Sig == ""){
wx.showToast({
title: '请先验签',
icon: 'loading',
duration:
})
}else{
Sig = RSA.b64tohex(Sig)
var ver = verify_rsa.verifyString("signData", Sig)
console.log('验签结果：' + ver)
this.setData({
output: ver
})
}
},
