gpgdir supports recursively descending through a directory in order tomake sure it encrypts or decrypts every file in a directory and all of itssubdirectories. In addition, gpgdir is careful to not encrypt hidden files anddirectories. Other features include the ability to interface with thewipe program for secure file deletion, and the ability to obfuscatethe original filenames within encrypted directories. It should be noted that gpgdirisnot intended as a replacement or competitor to good filesystemencryption solutions such as encfs - it is merely an effort to apply GnuPG recursivelyto files since GnuPG itself doesn't offer this capability.

As an example of gpgdir operations, here is the outputfor recursively encrypting the GnuPG-Interface directory in the gpgdir sources (notethat the "t" directory is excluded from the command line):[mbr@minastirith ~/src/gpgdir]$ gpgdir --Exclude "GnuPG-Interface/t" --encrypt GnuPG-Interface
[+] Executing: gpgdir --Exclude GnuPG-Interface/t --encrypt GnuPG-Interface
