plan A:
if you haven't specified a session name, the default would be "hashcat". therefore, you only need to call
./hashcat64.bin --restore
not even need to specify the session name if it was default. - just did the same a few minutes ago.
plan B:
doesn't make much sense after having plan A, but just to mention it: even if you have lost a session or restore wouldn't work, if you remember the percentage before rebooting, then use --keyspace with the same hashcat parameters to show the total keyspace, and by multiplying the percentage with keyspace you can calculate the offset for --skip .... so it will start at that position. also works, also did it. obviously "plan A" is way better/more nice ...
