What john format should be specified to crack an 18 character Windows password?
To crack an 18-character Windows password, the NT format should be specified. NTLM (NT) is the password hash format used by Windows for user authentication and is suitable for cracking longer passwords, unlike the outdated LANMAN format that is restricted to 14 characters. SHA256 is not typically used by Windows for password hashing, and MS-CACHE relates to cached credentials rather than standard password hashing.
The answer is C. NT
To crack an 18-character Windows password, you would typically use the "NT" (NTLM) format in John the Ripper. The correct answer is: C. NT Explanation: LANMAN (A): LANMAN is an outdated and insecure password hash format used in older versions of Windows. It is limited to a maximum of 14 characters and is not suitable for cracking an 18-character password. SHA256 (B): SHA256 is a cryptographic hash function used for more secure password storage. However, Windows typically uses NTLM (NT) for password hashing, not SHA256. NT (C): NTLM (NT) is the password hash format used by Windows for user authentication. It is commonly used for password cracking in John the Ripper and similar tools. MS-CACHE (D): MS-CACHE is associated with cached credentials and not directly used for password cracking. The format used for password cracking is typically NTLM. In John the Ripper, you would use a command like the following to specify the "NT" format: bash john --format=NT hashfile
