Many users have requested that I add directory encryption to
GPGFileTool, a gpg front-end on OS X for performing cryptographic
operations on files. GnuPG doesn't do this itself, but there are many
ways in which I can wrap up directories into a single file for them.
Initially I thought to tar the directories before encryption/signing
since this is a very compatible format and on Mac OS X will only cause
problems for files with resource forks (I plan to eventually add
support for some other archival format, but I think tar is a good
start). The problem is that I can't find a way to use tar without
writing a file. I'd like to use pipes, although that probably isn't
The best that I can come up with so far is to write the archive to disk
in a special directory in the user's home folder with permissions 700,
read in the file's data, and then immediately use rm -P to securely
delete the file.
Any suggestions on better ways to do this would be appreciated.
