We miss a graphical environment, especially a file browser will not have to enter the path manually using the keypad on the PSP. But the operation itself is correct, perfectamnte encrypts and decrypts any type of files. But beware, if you forget the password can not ever retrieve the original file, because a program, for security, the key is not stored anywhere.
