前言微信小程序在后端进行预付单操作后，由前端调起支付接口，此时需要对参数进行SHA256withRSA签名计算。计算签名的实现废话少说，直接看东西const{KJUR,KEYUTIL}=require('jsrsasign');constjsr=require('jsrsasign');//AuthorHermit-xx2023-06-27functionsha256WithRSA(message,privateKey){//创建RSAKey对象constrsaKey=KEYUTIL.getKey(privateKey);//进行SHA256withRSA签名constsignature=ne

个人经验，这三个加密库的组合是最佳解决方案crypto-js、jsrsasign、jsencryptcrypto-js进行AES对称加密npmicrypto-jsimportCryptoJSfrom'crypto-js'//加密varciphertext=CryptoJS.AES.encrypt('message','key').toString();//解密varbytes=CryptoJS.AES.decrypt(ciphertext,'key');varoriginalText=bytes.toString(CryptoJS.enc.Utf8);console.log(originalT

我正在使用BouncyCaSTLe库在C#中生成签名，如下所示:varprivateKeyBase64="MIGTAgEAMBMGByqGSM49AgEGCCqGSM49AwEHBHkwdwIBAQQgg8/MbvGGTDMDpfje8lQBZ8st+l3SK7jRl7OWlyUl/VagCgYIKoZIzj0DAQehRANCAARkQIUpkKbxmJJicvG450JH900JjmJOGdlMCZl3BIXvPBBKkaTMsQc6l3O4vJA6Yc23nr3Ox/KwFUl6gdo5iTqV";varpublicKeyBase64="MFkwEwYHKoZIzj0CAQYIK
