文本加密解密，自定义加密后密文内容

我很忙！

说明

根据自定义密文内容，进行加密，

效果图

class BeastTranslator {
    constructor() {
        // 构造函数，初始化时设置字符映射表,自定义密文内容，可随意调整，建议三个字符加一个符号
        this.sounds = ['我', '很', '忙', '!'];
    }

    beastToHex(beastStr) {
        let hexStr = "";
        for (let i = 0; i < beastStr.length; i += 2) {

            let j = this.sounds.findIndex(item => item === beastStr[i]);
            let k = this.sounds.findIndex(item => item === beastStr[i + 1]);
            k = (j * 4 + k - i / 2 % 16 + 16) % 16;
            // 计算对应的十六进制值
            hexStr += k.toString(16).toUpperCase();
            // 将十六进制值转换为大写字符串并添加到结果中
        }
        return hexStr;
    }

        let buffer = "";
        for (let i = 0; i < hexStr.length; i++) {
            let k = (parseInt(hexStr[i], 16) + i % 16) % 16;
            // 计算对应的字符索引
            buffer += this.sounds[Math.floor(k / 4)] + this.sounds[k % 4];
            // 根据索引从字符映射表中获取字符并添加到缓冲区中
        }
        return buffer;

            // 每四个字符一组进行处理
            buffer += String.fromCharCode(parseInt(hexStr.substr(i, 4), 16));
            // 根据十六进制代码获取对应的字符并添加到缓冲区中
        }

            // 遍历输入字符串
            hexStr += ("0000" + str.charCodeAt(i).toString(16)).substr(-4).toUpperCase();
            // 将字符的 ASCII 码转换为十六进制字符串并格式化为四位，添加到结果中
        }
        return hexStr;
    }

    setSoundsFromBeast(beastStr) {
        this.sounds[0] = beastStr[2];
        // 设置字符映射表的第一个字符
        this.sounds[1] = beastStr[1];

        return this.hexToText(hexCode);
        // 将十六进制转换为普通文本字符串并返回
    }

        if (soundMap) {
            this.setSounds(soundMap);
            // 如果有提供自定义字符映射表，则设置字符映射表
        }

        return [soundMapForBeast[0], soundMapForBeast[1], soundMapForBeast[2], beastSound, soundMapForBeast[3]].join("");
        // 返回处理后的字符串
    }
}

function testTranslator() {
    let translator = new BeastTranslator();
    // 待加密文本
    let strToEncode = "吾爱破解";
    console.log('-----------------------------------------');
    let encodedStr = translator.parseToBeast(strToEncode);
    console.log("加密后：", encodedStr,'\n');
    let decodedStr = translator.parseToNormal(encodedStr);
    console.log("解密后：", decodedStr);
    console.log('-----------------------------------------');
}

testTranslator();

这想法不错，只是效率有点低，密文相对于明文的长度增长了数倍，但解密难度并不高。

请问这个怎么用的 大佬  txt 可以加密吗

我很忙！

可以，只要以字符串传入都能转换
