One-way hashing

Hashing is a very useful tool for encrypting data in PostgreSQL. When we use one-way hashing, the transformation of our data from plaintext to encrypted text happens at an atomic level. That means it’s irreversible and can’t be undone once completed. The encryption algorithm ensures that the original data can never be reconstructed from the encrypted data.

One-way hashing is sometimes called ...
