Cryptomfs is a MacFUSE implementation of cryptofs by Christoph Hohmann.

Cryptomfs will use a directory to store encrypted files. The mountpoint will provide access to the unencrypted data, but no data is ever written to the harddisk without encryption.

Update 23 Feb 2010

New version available: 1.1. If you have any previous versions of Cryptomfs installed please move them to the trash before installing.

Changes from version 1.0:

• Default mount location is now <.cryptofs package root>/mount.
• Added application preference to terminate application after filesystem has mounted.
• Added command line utilities mkcryptomfs and mount_cryptomfs. Symlinks are created in /usr/bin/ during install.
• Passwords can now be specified on the command line.

Note When attempting to mount a Cryptomfs 1.0 filesystem, you will be asked to type a 'new' password. You should type the password you used when creating the filesystem. If you make a mistake in the password entry follow the steps on the wiki page FixMistypedPassword. See RemoveKeychainEntries to clean up any old/mistyped passwords.

Requirements

• Requires Mac OS X 10.5 (Leopard).
• Must have MacFUSE (http://code.google.com/p/macfuse) installed.

Features

• Filesystems are packages so they behave like disk images in Finder (e.g., Double clicking on the .cryptofs package will mount the filesystem.)
• Passwords are entered using a dialog.
• Keychain support.
• Custom volume names for mounted filesystems.
• Custom icon support for mounted filesystems.
• Easy creation of new filesystems.
• Filesystem configuration is saved in a plist file.
• Filesystems can be mounted using cryptofs and fuse in other operating systems. Good for sharing encrypted data on a dual boot system.
