Generating a hash for Cassandra table data

I wanted to check if there is a way to generate a hash or any kind of unique identifier for all the data in a Cassandra table at a given point of time? I can't find anything to generate a hash directly but even if there's a way to create a hash of each column and the data contained in it, that could be useful. I wish to use this for maintaining a record of the table to see if it has been modified without authorisation.
