To encrypt a file, before compression you must specify a password, or directly in the compressed file in the specified name and parameters dialog.

In command line mode, use the switch-p [password].

In the WinRAR graphical interface, you enter the password you can press Ctrl + P or in the File menu, select "Set default password" command.

Another way is to click the lower left corner of the WinRAR window to the bottom of the key icon. In the compressed file name and parameters dialog "Advanced Options" group, press the "Set Password" button to enter the password.

Different from ZIP, RAR format not only allows the data, and other compressed file that can be perceived areas: file name, size, attributes, comments and other blocks can be encrypted. If you wish to do so, you need the password dialog box set "Encrypt file names" option, or use the command line mode-p [password] switch-hp [password]. Encrypted files in this way, even if no password can not see the file list.

When no longer needed, do not forget to delete the password. Otherwise, you may then encrypt the other compressed files, but do not want to use the same set of passwords. To delete a password, just enter an empty string to replace the original password, or to close WinRAR and restart again. When a password is present, the key icon is red, otherwise it is yellow. And, when you use the password starts to compress operation, the title bar compressed file name and parameters dialog box will blink twice.

If you compress the file name and parameters dialog box, enter it directly, you do not need to remove the password. This differs from other methods, such passwords only operate effectively in a single compressed, and will be automatically deleted after it.

When extracting encrypted file, you can start operating before without the prior password. If WinRAR encounter encrypted files, but not to enter a password before extracting it, it will prompt for the password, if you forget the password, you can use the rar password recovery to find back the password.
