CRYPTDIR(1)                                           CRYPTDIR(1)

NAME
       cryptdir - encrypt/decrypt all files in a directory

SYNOPSIS
       cryptdir [ dir ]
       decryptdir [ dir ]

INTRODUCTION
       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.

NOTES
       When encrypting, you are prompted twice for  the  password
       as  a  precautionary  measure.   It would be a disaster to
       encrypt files 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.

BUGS
       The man page is longer than the program.
