Hexdump of your key file
How to crate this Hexdump?
Hexdump of the encrypted DB:
How to crate this 256 Hexdump?
Screenshots Program output using -v and -f
Additional context
For whatever reason I can't extract a WhatsApp database that is end-to-end encrypted
I put the 64 character key
I use the beta version of WhatsApp Business
I tried with -f and it didn't work either
What do you think could be the problem?
@aviv926 commented on GitHub (Aug 30, 2023):
No problem, I just took a new backup with a new key and everything works as it should.
thanks for this amazing project
@ElDavoo commented on GitHub (Aug 30, 2023):
The program says the checksum is OK, so the data is intact, but the authentication failed, which means the key is wrong or does not match with the database.
Maybe that database backup was taken before you generated the new key?
Anyway, Thanks for telling me it works on WA business too!
@aviv926 commented on GitHub (Aug 30, 2023):
Thanks for your hard work!!
By the way, can you explain to me how to create the requested Hexdump?
@ElDavoo commented on GitHub (Aug 30, 2023):
On Linux you use the CLI program hexdump.
On windows you can use HxD.
Anyway it's not needed anymore.
@aviv926 commented on GitHub (Nov 4, 2023):
I saw the repeated comment just now
Thanks for your reply and as always thanks for this project
I thought you might want to integrate this project into your project or refer to this project
https://github.com/ddz/whatsapp-media-decrypt
What do you think?
@ElDavoo commented on GitHub (Nov 9, 2023):
Why should I do that?
@aviv926 commented on GitHub (Nov 9, 2023):
Both of you deal with decrypting and encrypting files in the context of WhatsApp, I assume that whoever enters your project will find the project I linked useful to him as well.
@ElDavoo commented on GitHub (Nov 10, 2023):
The context of whatsapp is too broad. That projects decrypts encrypted media stored (temporarely) in whatsapp servers. This project aims to decrypt local backups (and soon, cloud-downloaded projects - but it won't download files). So in a certain way these two projects are unrelated.
Anyway, I see that people are proposing things in issue so I think I will enable discussions.
@aviv926 commented on GitHub (Nov 10, 2023):
I got you :) In fact, I was interested in understanding the understanding behind the encryption of WhatsApp, so your project and the project I linked were in context for me.
Anyway, thank you for this project !!!
By the way, can I ask if you created the project using an official WhatsApp document to understand the encryption algorithm?
@ElDavoo commented on GitHub (Nov 13, 2023):
no, just guessing the file format and building on previous work
