Hello,
I got a mobile phone that encrypt the files on its microSD card.
I know it making the key and then XOR it with the files.
I like to find the algorithm that it used to get the key file. It doesn't not repeat the key even with 50MB file.
I also know the key generated according to the phone number but I don't know if it use the phone number as number or as text.
I got the keys it generate by uploading empty files (files that contain only 0x0 so it generated the key, xor it with 0x0 so it keep the key [as long as I know a xor 0 = a])
So is there a way to find the algorithm ?
phone numbers are 10 digits and here are some 1kb files that encrypted by mobile - the name of the files are the phone numbers that they got encrypted with and the data is the key files the mobile generated to encrypt the files.
