Generate irreversible tokens

An irreversible token is a value that can't be converted back to its original value. These tokens are used to anonymize data allowing them be used for data analytics and machine learning. Irreversible tokens also plays an important role in GDPR compliance by ensuring enhanced privacy and data anonymization.
