+## Plugins (Built on Core)
 
-The internal “aes” plugin has been deprecated.
-Use the standalone **PAXECT AEAD Hybrid Plugin** instead (Hybrid AES-GCM / ChaCha20-Poly1305 — fast, zero dependencies, and cross-OS).
-Any screenshots or references to “aes” are now obsolete and maintained only for historical context.
