Detailed Description

Dispatcher layer for software AEAD implementations.

Dispatcher layer for the software AEAD implementations.

Dispatches multipart AEAD operations to the appropriate per-algorithm software implementation based on the active algorithm.

This module provides a common interface that dispatches to specific software AEAD implementations (such as AES-CCM) as a workaround for hardware limitations with multipart operations.

Note

These APIs are for internal use only. Applications must use the PSA Crypto API (psa_* functions) instead of calling these functions directly.
