24# DESCRIPTION:
25# ZFS should receive streams from raw incremental sends.
26#
27# STRATEGY:
28# 1. Create an encrypted dataset
29# 2. Snapshot the dataset
30# 3. Create a file and get its checksum
31# 4. Snapshot the dataset
32# 5. Attempt to receive a raw send stream of the first snapshot
33# 6. Change the passphrase required to unlock the original filesystem
34# 7. Attempt and intentionally fail to receive the second snapshot
35# 8. Verify that the required passphrase hasn't changed on the receive side
36# 9. Attempt a real raw incremental send stream of the second snapshot
37# 10. Attempt load the key and mount the dataset
38# 11. Verify the checksum of the file is the same as the original
39#
