gpgdir is a script that encrypts and decrypts
directories using a GPG key specified in
~/.gpgdirrc. It supports recursively descending
through a directory in order to make sure it
encrypts or decrypts every file in a directory and
all of its subdirectories. All file mtime and
atime values are preserved across encryption and
decryption operations. In addition, gpgdir is
careful not to encrypt hidden files and directories.
