Class KeyDerivationFunctionPreviewNotes

java.lang.Object
net.jrodolfo.java_evolution.java24.key_derivation.KeyDerivationFunctionPreviewNotes
public class KeyDerivationFunctionPreviewNotes extends Object
Explains the Key Derivation Function API preview in Java 24.

Cryptographic systems often need to derive purpose-specific keys from shared secret material instead of reusing the same raw bytes everywhere. A Key Derivation Function, or KDF, combines input key material, salt, context, and an output length to produce derived key material.

Java 24 previewed a standard API for that operation, and Java 25 finalized it. This package keeps the Java 24 feature as preview notes because the final executable example belongs in the Java 25 key-derivation module.
