RSA加解密问题(jsencrypt与java前后端加解密):推荐使用博客内的SM2加解密
前端加解密(需先引入-jsencrypt.min.js):
1 2 3 4 5 6 7 8 9 | var encrypt = new JSEncrypt(); var publicKey = "" ; encrypt.setPublicKey(publicKey) // 设置公钥 var encrypted = encrypt.encrypt( "对数据进行加密" ); // 对数据进行加密 var encrypt = new JSEncrypt() var privateKey = "" ; encrypt.setPrivateKey(privateKey) // 设置私钥 var param = encrypt.decrypt(encrypted); // 对数据进行解密 |
