    Hi:

    I read two very interesting howtos:

    A. http://www.howtoforge.com/automatically-unlock-luks-encrypted-drives-with-a-keyfile

    B. http://www.howtoforge.com/remotely-unlock-fully-encrypted-debian-squeeze

    Both are interesting. I could not figure out how to:

    1. make the bootloader to load keyfile from USB (like in A above) which also has a passphrase to authenticate remotely using ssh (like in B) or say a combination of A and B?

    OR

    2. make the bootloader to first search for keyfile, if there is a keyfile, the unencrypted volume would be decrypted (like A above) . If no keyfile found, it can alternatively wait to be remotely get passphrase (as in B above) or say either-keyfile-else- passphrase approach?

    Thanks!
