Detailed Description

Software implementation of AES-GCM (Galois/Counter Mode)

Software implementation of the AES-GCM (Galois/Counter) mode.

This module provides a software-based implementation of AES-GCM for use 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.
