How to crack iTunes backup password with hashcat?

[kiara]

did u try what atom suggest ?

Where to find hash, salt and iteration number in the backup to make up an input für hc?

well before posting i was thinking the same thing, thats why i ask

how do u take out the hash of the itune backup

i followed https://hashcat.net/wiki/doku.php?id=example_hashes
which shows 

12000
PBKDF2-HMAC-SHA1
sha1:1000:MzU4NTA4MzIzNzA1MDQ=:19ofiY+ahBXhvkDsp0j2ww==

but nothing about taking out the hash from the encrypted backup.
