I tried searching the web for a sample encrypted RAR file, but I only found this one: http://www.philipp-winterberg.com/software/rar_faq_encrypted_password_protected_secured_files.php#faq_protected_test_file http://www.philipp-winterberg.com/download/example_password_protected.rar which is not supported: $ ./drar example_password_protected.rar > pw-example_password_protected ! example_password_protected.rar : RAR -p mode support not implemented yet, more beer required Perhaps you could create this wiki page: http://openwall.info/wiki/john/sample-non-hashes and upload sample files to crack to there (tiny and small ones, please)? > I am moving on to adding support for zip archives and FileVault stuff. Sounds great. Thanks again, Alexander
