Tried again here, not working. Do you know if it is possible to sniff the iphone connection and get the md5? I have generated the hash from the duplicated mac and want to check that it is identical.

The password algorithm changed in the lasts versions of Whatsapp, at least in iPhone. You can get a Base64 of the md5 from the application directory, but it doesn't match the imei or mac md5. I am trying to break mine with hashcat to see what kind of pattern it follows.

I guess you are trying to do the MD5 yourself, while you should simply just enter the mac address with the : . The script will automatically generate the hash for u.
