To achieve this we use different type of Cryptography: - Symmetric, Asymmetric and Hashing. Very common use of cryptography is sending encrypted link in the automated email, such as password resetting. But there also comes situation when we've to keep encrypted data in the database. In this case most of the fields of database tables are encrypted and you will not able to see any data except the unique, primary key, foreign key fields and searching fields.
