cryptdir - encrypt/decrypt all files in a directory
cryptdir
[ dir ]
decryptdir [ dir ]
cryptdir encrypts all files in the current
directory (or the given directory if one is provided as an argument). When
called as decryptdir (i.e., same program, different name), all files are
decrypted.
When encrypting, you are prompted twice for the password
as a precautionary measure. It would be a disaster to encrypt files with
a password that wasn't what you intended.
In contrast, when decrypting,
you are only prompted once. If it's the wrong password, no harm done.
Encrypted
files have the suffix .crypt appended. This prevents files from being encrypted
twice. The suffix is removed upon decryption. Thus, you can easily add files
to an encrypted directory and run cryptdir on it without worrying about
the already encrypted files.
The man page is longer than the program.
