Hash using sha2-512
As of this writing (Mid 2019) it's still secure to use this function and 512 bits should suffice.
Hash sensitive information using MySQL
It digests (i.e. summarizes) strings of any size into a base-64 string, having 512 bits in length.
Apparently, this feature was added in MySQL version 5.5.5. (Official Documentation for MySQL encryption functions)[http://dev.mysql.com/doc/refman/5.6/en/encryption-functions.html].
INSERT INTO testing_table(id, name) VALUES (null,sha2('foo',512))
