crypto-js实现加密解密

1、DES加密

           function encryptByDESModeEBC(str,key){//str为待加密字符串，key为密匙
            var keyHex = CryptoJS.enc.Utf8.parse(key);
            var encrypted = CryptoJS.DES.encrypt(str, keyHex, {
            mode: CryptoJS.mode.ECB,
            padding: CryptoJS.pad.Pkcs7
            });
            return encrypted.ciphertext.toString();
        }

2、DES解密

              function decryptByDESModeEBC(ciphertext,key){//ciphertext为带解密字符串，key为密匙
            var keyHex = CryptoJS.enc.Utf8.parse(key);
            var decrypted = CryptoJS.DES.decrypt({
            ciphertext: CryptoJS.enc.Hex.parse(ciphertext)
            }, keyHex, {
            mode: CryptoJS.mode.ECB,
            padding: CryptoJS.pad.Pkcs7
            });
            var result_value = decrypted.toString(CryptoJS.enc.Utf8);
            return result_value;
        }

3、AES加密

                function getAES(data){ //加密
            var key  = 'AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA';  //密钥
            var iv   = '1234567812345678';  //十六位十六进制数作为密钥偏移量
            var encrypted =getAesString(data,key,iv); //密文
            var encrypted1 =CryptoJS.enc.Utf8.parse(encrypted);
            return encrypted;
        }

                function getAesString(data,key,iv){//加密
            var key  = CryptoJS.enc.Utf8.parse(key);
            var iv   = CryptoJS.enc.Utf8.parse(iv);
            var encrypted =CryptoJS.AES.encrypt(data,key,
                {
                    iv:iv,
                    mode:CryptoJS.mode.CBC,
                    padding:CryptoJS.pad.Pkcs7
                });
            return encrypted.toString();    //返回的是base64格式的密文
        }

4、AES解密

              function getDAes(data){//解密
            var key  = 'AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA';  //密钥
            var iv   = '1234567812345678';  //十六位十六进制数作为密钥偏移量
            var decryptedStr =getDAesString(data,key,iv);
            return decryptedStr;
        }

                function getDAesString(encrypted,key,iv){//解密
            var key  = CryptoJS.enc.Utf8.parse(key);
            var iv   = CryptoJS.enc.Utf8.parse(iv);
            var decrypted =CryptoJS.AES.decrypt(encrypted,key,
                {
                    iv:iv,
                    mode:CryptoJS.mode.CBC,
                    padding:CryptoJS.pad.Pkcs7
                });
            return decrypted.toString(CryptoJS.enc.Utf8);     
        }

5、注意：js的前端加密不能与java加密代码写的代码混合使用
