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-----' var publicKey = '-----BEGIN PUBLIC KEY-----MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCoChRDJ6e7BTE5yYBIS + NGYBpDs7ftEematqhvMmOFcJng7qjJk + yJ1j7DCqbCD2f / BI6gTfGXASiYuO6kklZu8Pkw4HAUkaaGyhaC8Z+ TMg79PPRz5hziEdFXPTdXvXudiXbI2Wi6D90ZaSwN6ZHs7Mtc5VgGK3jxS35iLm+ oAQIDAQAB-----END PUBLIC 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 <=0){ wx.showToast({ title: '请先加密', icon: 'loading', duration: 1000 }) }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: 1000 }) }else{ Sig = RSA.b64tohex(Sig) var ver = verify_rsa.verifyString("signData", Sig) console.log('验签结果:' + ver) this.setData({ output: ver }) } },
