Unknown X-VC value

[delta-kor]

Thank you very much for your selfless dedication, can you provide detail documentation for the X-VC value?

client.login('email', 'password', 'device id', 'xvc' /* this */);

Tried to find the X-VC value by capturing connection but it was blocked by kakao client. Where can I find the X-VC value?

Thank you again for your hard work.

X-VC value is security related thing that made with email, password, user-agent and device id as far as I know. If you put wrong X-VC value here, your login request will be rejected. I extracted them by dumping memory of official client program.

Note: Currently I'm not maintaining this project unless there are major bug which affects my bot.

I am so pleased to hear from you. I think I got the proper X-VC value but it still doesn't work.

I got error Error 30. Someof field values are wrong , but I rarely got Received wrong response: Access login ERR 12.

new TalkClient('NAME' /* here! */);

Does the TalkClient name should be device's name ( DESKTOP-XXXXXXX ) ?

Also, is the deviceUUID value from login method base64-like-string from registry?

I am very thankful that you're considering my problem. Thank you for your attention to this matter and look forward to hearing from you again soon.

X-VC value is security related thing that made with email, password, user-agent and device id as far as I know.

Most error 30 is caused by X-VC value mismatch. Current node-kakao's A header for auth is "KT/3.0.6 Wd/10.0 ko". Current official client is 3.1.1 so it is outdated.

You have to match version string in kakao-api.ts in kakao-api.ts

static get Version() {
    return '3.0.6';
}

static get InternalAppVersion() {
    return `${this.Version}.${this.InternalAppSubVersion}`;
}

static get InternalAppSubVersion() {
    return '2319';
}

static get OSVersion() {
    return '10.0';
}

static get Language() {
    return 'ko';
}

static get AuthUserAgent() {
    return `KT/${KakaoAPI.Version} Wd/${KakaoAPI.OSVersion} ${KakaoAPI.Language}`;
}

^ this

I also think I got the right X-VC header (and above version code), but ERROR 30 keeps happening. Can you tell me exactly where i can find device_UUID ? Is this HKEY_CURRENT_USER\SOFTWARE\Kakao\KakaoTalk\DeviceInfo\2020~XXX\dev_id in pc registry ? ---------SOLVED----------- found it in client memory dump

Thank you @storycraft . It worked for me. I got a proper X-VC value by memory dumping and it worked. Thank you again for taking the trouble to help me. I do appreciate it. Good luck in everything

Good to hear it worked well from you. There is device uuid thing in registry but It's not complete key. You need to extract it like x-vc value.

Closing this issue.
