Why each option
John the Ripper is a password auditing tool used to recover plaintext passwords from stolen hash files through dictionary, brute force, or rule-based attacks.
FTP is a network protocol for transferring files between hosts and cannot crack, parse, or analyze the contents of a stolen credential file.
John the Ripper is a well-known open-source password cracking utility. When Eve runs it against secret.txt - which likely contains password hashes - the tool systematically attempts to recover the plaintext credentials using wordlists or brute force methods. Stealing a password hash file and running John the Ripper locally is a classic offline password cracking attack that bypasses account lockout controls.
Encrypting a file requires cryptographic utilities such as gpg, openssl, or a similar tool; John the Ripper performs password cracking, not encryption.
John the Ripper is designed specifically to recover passwords from hash values, not to display or read the raw contents of a file.
