How to calculate the hash of all strings?

Question

MySQL

Usually, to check the integrity, I used
SHA1(CONCAT(`col1`, `col2`, `col3`))
But I would like to get a hash of ALL rows from the database.

So far, I have solved the issue using php, where the array is filled with strings and a hash is created.

Can this somehow be done using just mysql?
