Subject: [PATCH] Hash the contents as that is much faster

Hashing the file takes over 0.100ms (due to having to load the file again), which arguably is not much, but considering that hashing the content already stored in memory is less than 0.007ms which is an order of magnitude faster, for something that does not affect the feature.
