我希望我能得到幫助，因?yàn)槲也恢罏槭裁次业?AES-GCM 實(shí)現(xiàn)會(huì)破壞文件編碼。我有一個(gè) API，它使用 1 個(gè)函數(shù)通過 AES-256-GCM 進(jìn)行加密/解密。（使用 KEY=32 個(gè)隨機(jī)字節(jié)的緩沖區(qū)）這是功能：const aes256gcm = (key) => {    const ALGO = 'aes-256-gcm';    const encrypt = (str) => {        try {            const salt = crypto.randomBytes(64);            const iv =  crypto.randomBytes(32);            let derivedkey = crypto.pbkdf2Sync(key, salt, 55000, 32, 'sha512');            const cipher = crypto.createCipheriv(ALGO, derivedkey, iv);            let encrypted = Buffer.concat([cipher.update(str), cipher.final()]);            const tag = cipher.getAuthTag();            let buffer = Buffer.concat([salt, iv, encrypted]);            encrypted = {                tag: tag,                buffer: buffer            }            return encrypted;        } catch (e) {            console.log(e);        }    };    const decrypt = (data, authTag) => {        try {            const salt = data.slice(0, 64);            const iv = data.slice(64, 96);            const text = data.slice(96, data.length);            authTag = new Buffer.from(authTag, 'base64');            let derivedkey = crypto.pbkdf2Sync(key, salt, 55000, 32, 'sha512');            let decipher = crypto.createDecipheriv(ALGO, derivedkey, iv);            decipher.setAuthTag(authTag);            let decrypted = decipher.update(text, 'binary') + decipher.final();            return decrypted;        } catch (e) {            console.log(e);        }    };    return {        encrypt,        decrypt    };};使用此代碼，我將結(jié)果加密并寫入文件：const aesCipher = aes.aes256gcm(aes.loadKey(path.resolve(__dirname, `key`)));            const encrypted = aesCipher.encrypt(file.data);            if (encrypted !== undefined) {                fs.writeFile(`${file.name}.enc`, encrypted.buffer, function (err) {                    if (err) return console.log(err);                    console.log(`${file.name}.enc successfully created`);                });            }我的輸入/輸出文件的差異： 差異那么，我做錯(cuò)了什么？我的加密過程好嗎？為什么這只適用于 .txt 文件？
