How do you currently use ecryptfs? (In reply to comment #1) > How do you currently use ecryptfs? > I am trying out backing up to an external disk - I set up a key with a passphrase and mount the disk using: EDIR=/root/.ecryptfs/pki/openssl KEY="key=openssl:keyfile=${EDIR}/key.pem" PASS="passfile=${EDIR}/pass" CIPHER="cipher=aes" EBYTES="ecryptfs_key_bytes=32" THRU="passthrough=no" ARGS="${KEY},${CIPHER},${EBYTES},${THRU},${PASS}" mount -t ecryptfs -o "${ARGS}" /${USBDISK} /${USBDISK} if [ $? -ne 0 ] then log "Unable to mount encrypted ${USBDISK} ..." exit 1 fi [I will eventually move the keys to another external USB key.] I then run an rsync to copy the backups to the external drive. We have 3 external drives which are rotated every day - at least one is mandated to be offsite. Incidentally, I tried downloading the source tarball from ecryptfs.sourceforge.net - the ecryptfs-30 package also failed - the -18 worked so it appears to be a problem with the original source... This is not passphrase method but openssl. Please unset gpg USE flag and set openssl USE flag. Then see if you get these two modules when you use ecryptfs-manager. Please also attach the log of /var/log/messages with you fail to mount.

V30 only gives you one option 1 -openssl. If you select openssl in either V18 or V30 you get a prompt for the passphrase. In V18 you subsequently get a prompt to confirm the passphrase - in V30 no such prompt appears and you return to the main menu of ecryptfs-manager. In V30 if you select option 3 again you get 2 options both of which are openssl. If you repeat this cycle the next iteration gives you three options all opensssl and so on ad nauseam. Also V30 does not create any keyfiles in the requested directory. (usually /root/.ecryptfs/pki/openssl/key.pem). So ecryptfs-manager in V30 is seriously non-functional - V18 works like a charm. I already disabled gpg. openssl is already set (it does not have to be set globally). I did not even attempt to mount because there seemed no point if the key.pem file did not exist. I have subsequently downgraded to V18 via the source tarball and everything works as expected. (In reply to comment #4) > (In reply to comment #3) Additional info when using ecryptfs-18 from source.

I got ecryptfs working at my house successfully using ecryptfs-18. However at my place of work ecryptfs is broken.Investigation shows this is ecryptfs-30 - unfortunately the maintainer has removed ecryptfs-18 so I cannot downgrade. The symptoms are : ecryptfs-manager does not offer the passphrase option as well as openssl (ecryptfs-18 always offered both openssl and passphrase when creating a new public/private key pair) selecting openssl results in a prompt of the key location and then for the passphrase. entreing the passphrase once goes back to the main menu (ecryptfs-18 asked for verification). The location where the keyfile is meant to be stored is *not* created (/root/.ecryptfs/pki/openssl/key.pem?). starting ecryptfsd gets an error about not being able to load the gpg module.
