jiru / kakaodecrypt Goto Github PK

I did my research and the new prefix should be "tony".

And I always have the following error running the program. I don't know what's wrong.

Traceback (most recent call last):

First, sorry for my bad English :(

I have KeyError 'enc' similar to issue #13
chat_logs are successfully decoded and make chat_logs_dec table, but i think there is an issue decoding chat_rooms.

Here is my error log:

PS kakaodecrypt-master> python .\kakaodecrypt.py -u 54976745 apps\com.kakao.talk\db\KakaoTalk.db
Created table 'chat_logs_dec'.
Traceback (most recent call last):
  File "\kakaodecrypt.py", line 197, in run
    enc_type = row[ col_defs['enc'] ]
KeyError: 'enc'

During handling of the above exception, another exception occurred:

    KakaoDbDecrypt.run(args.db_file, enc_table, dec_table, enc_fields, args.p, args.u)
  File "kakaodecrypt.py", line 205, in run
    enc_type = v_data['enc']
KeyError: 'enc'

and codes where error appeared:

using env : windows 10 pro version 22H2 (os build 19045.3803)
python 3.9.13 64-bit
pycrypthodome, pycryptodome == 3.19.0

I uploaded my kakaotalk.db file at google drive.
If u need db file, let me know how to share file link (like e-mail address or something else).
Thank you.

잘 진행되다가 갑자기 뻗더라고요

I decrypted chat_logs using your code.
It creates friends_dec table, However, It doesn't work.

name, nickname, and other things returns blank, blob, or null.

I think It doesn't work because user_id doesn't exist in friends table.
In my case, It has these Integer fields : _id, contact_id, id, type, chat_id, brand_new, blocked, favorite, position, user_type, story_user_id, account_id, hidden, member_type, enc, created_at, new_badge_update_at, new_badge_seen_at.
There are no user_id.

If you need my database, I'll send it to you.

it seems its not working in large size userId, which is used in openchatting
can you please check it?

test case :
KakaoDecrypt.decrypt(77289285161409090,26,"6ooWLeWv/zcVSNsm8X44SOqc/Yg9u2wYe9HolLxmLOw=")

C:\Users\123\Desktop\kakaodecrypt-master>python kakaodecrypt.py -p KakaoTalk.db

C:\Users\123\Desktop\kakaodecrypt-master>

and open kakaotalk.db ->
table (0)
index (0)
view (0)
trigger (0)
DB browser for sqlite

Be use like
contents = KakaoDecrypt.decrypt(387216304, 31, "RcrN4TWyfEL0p6O+yWtOpw==")

아직도 복호화가 되는건가요? 돌려보면
C:\pentest\virus>python decryt.py -p KakaoTalk.db
