Please see the file COPYING for details. -For documentation, please see the files in the doc/ subdirectory.

Thompson - Kent Yoder -Web Site: http://ecryptfs.sf.net - -This software is currently undergoing development. Make sure to -maintain a backup copy of any data you write into eCryptfs. - -eCryptfs requires the userspace tools downloadable from the -SourceForge site: - -http://sourceforge.net/projects/ecryptfs/ - -Userspace requirements include: - - David Howells' userspace keyring headers and libraries (version - 1.0 or higher), obtainable from - http://people.redhat.com/~dhowells/keyutils/ - - Libgcrypt - - -NOTES - -In the beta/experimental releases of eCryptfs, when you upgrade -eCryptfs, you should copy the files to an unencrypted location and -then copy the files back into the new eCryptfs mount to migrate the -files. - - -MOUNT-WIDE PASSPHRASE - -Create a new directory into which eCryptfs will write its encrypted -files (i.e., /root/crypt). Then, create the mount point directory -(i.e., /mnt/crypt). Now it's time to mount eCryptfs: - -mount -t ecryptfs /root/crypt /mnt/crypt - -You should be prompted for a passphrase and a salt (the salt may be -blank). - -Try writing a new file: - -echo "Hello, World" > /mnt/crypt/hello.txt - -The operation will complete. Notice that there is a new file in -/root/crypt that is at least 12288 bytes in size (depending on your -host page size). This is the encrypted underlying file for what you -just wrote. To test reading, from start to finish, you need to clear -the user session keyring: - -keyctl clear @u - -Then umount /mnt/crypt and mount again per the instructions given -above. - -cat /mnt/crypt/hello.txt - - -NOTES - -eCryptfs version 0.1 should only be mounted on (1) empty directories -or (2) directories containing files only created by eCryptfs. If you -mount a directory that has pre-existing files not created by eCryptfs, -then behavior is undefined. Do not run eCryptfs in higher verbosity -levels unless you are doing so for the sole purpose of debugging or -development, since secret values will be written out to the system log -in that case. - - -Mike Halcrow -mhalcrow@us.ibm.com |
