GIAC Certified Incident Handler (GCIH) — Question 102

What john format should be specified to crack an 18 character Windows password?

Answer options

• A. LANMAN
• B. SHA256
• C. NT
• D. MS-CACHE

Correct answer: C

Explanation

The correct answer is C, NT, as it is specifically used for Windows password cracking and supports long passwords. LANMAN is outdated and cannot handle passwords longer than 14 characters, while SHA256 is a hashing algorithm not used for Windows password storage, and MS-CACHE is related to cached credentials, not directly to 18 character passwords.
