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 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.

BUGS

       The man page is longer than the program.
