Loop-aes provides no option to change the key/password for a partition. Using dd and two loop-devices is rather risky. What if the machine just hangs up after 100GB? All data gone? Well, I asked myself if there is a way to use some >1GB partition (swap or such) to store the data temporarily and pipe it further through the pipe. In case of some crash a restore-point could be set and re-encryption restarted or continued. But I have no idea what to enter in the command line in order to define how the decrypted blocks can be counted. For harddisk encryption this would be an interesting thing. Just in case someone gets a copy of your keyfile you may want do change it. Regards Peter -- Weitersagen: GMX DSL-Flatrates mit Tempo-Garantie!
