I need to access a hard drive that is encrypted with LUKS. The password provided is incorrect, however it is only incorrect by a character or so. The password itself is very strong and above 30 characters in length. How would one go about brute forcing their way into the hard drive with this information in mind to access the data or should the data loss simply be accepted?
John the Ripper Jumbo has LUKS format available. Use luks2john first, and then use JtR normally, walking through the characters one at a time to see which is wrong.
