Encrypting data written to an LVM snapshot with a different key












0














I have the following requirements:




  • I have an LVM volume A, encrypted with key K1 using LUKS.

  • I need to make a copy-on-write snapshot of A such that


    • Writes to A will continue to be encrypted under K1

    • Writes to the snapshot will be encrypted under K2, which is different from K1.




The use case is to allow the snapshot to be securely deleted by deleting the encryption key.



Is this possible?

My ISP isn't helping either so I'm looking for other ways to accomplish this. The router has telnet access so this seems like a way to change the credentials.
