The article details a new patch for PostgreSQL 18 that introduces SHA-256 and SHA-512 based password hashing (sha256crypt and sha512crypt) to the pgcrypto extension. It explains how the `crypt()` and `gen_salt()` functions work, shows examples of the new hash formats, and discusses the configurable iteration counts for these adaptive hashing algorithms.
