The post introduces the Key Derivation Function (KDF) API in Java, finalized for JDK 25, which standardizes the application of KDF algorithms like HKDF and Argon2. It aims to support secure cryptographic operations, including Hybrid Public Key Encryption, and aligns Java's security capabilities with post-quantum cryptography needs. The API allows custom implementations by security providers, enhancing Java's cryptographic extensibility.
