I presume it's to do with geli using OpenSSL libraries and so picking-up hardware acceleration where available. I think gdbe is being sidelined. > i need both encrypted partition and encrypted copies/DVDs. I'd be interested if anyone has a method for creating encrypted DVDs that still works. A couple of years ago I played around with encrypted CDs by using a 650Mb file as a backing store for an encrypted md partition and then just burning a CD with that file on it. The same technique can be extended to DVDs by using using two or more backing files with gconcat, to get around the problem that an ISO 9660 filesystem wont support a single 4.7GB file. It worked at the time, but recently I found that the technique no longer works, gbde wouldn't attach the device as it's read-only. I know the behaviour has changed, because I had the old scripts, that had worked before. It's still possible to access the data by copying the backing files to disk, but that's not very practical. I guess it may be possible to work around the problem with a union filesystem, but I haven't pursued that yet. I understand that it's possible to encrypt a DVD+RW as an ordinary partition, but that it's painfully slow. And I don't really want to use RW disks. _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
