Question
Eve stole a file named secret.txt, transferred it to her computer and she just entered these commands:
[eve@localhost ~]$ john secret.txt Loaded 2 password hashes with no different salts (LM [DES 128/128 SSE2- 16]) Press 'q' or Ctrl-C to abort. almost any other key for status 0g 0:00:00:03 3/3 0g/s 86168p/s 86168c/s 172336C/s MERO..SAMPLUI 0g 0:00:00:04 3/3 0g/s 3296Kp/s 3296Kc/s 6592KC/s GOS..KARIS4 0g 0:00:00:07 3/3 0g/s 8154Kp/s 8154Kc/s 16309KC/s NY180K..NY1837 0g 0:00:00:10 3/3 0g/s 7958Kp/s 7958Kc/s 1591KC/s SHAGRN..SHENY9 What is she trying to achieve?

Why each option
Eve is using John the Ripper, a password cracking tool, to attempt to recover plaintext passwords from hashes stored in secret.txt.
Encryption would require tools like gpg or openssl and would not produce hash-type detection output or cracking speed statistics.
John the Ripper does not read or display file contents - it parses password hashes and attempts to reverse them into plaintext credentials.
FTP is a network file-transfer protocol with its own dedicated client tools; the 'john' binary is a local password cracker and produces no FTP-related output.
John the Ripper (invoked via the 'john' command) is a well-known offline password cracking utility. The output showing the hash type (LM/DES), crack speeds measured in passwords-per-second (p/s), and incremental status updates is the standard runtime output of John the Ripper actively brute-forcing or dictionary-attacking password hashes extracted into secret.txt.
