Detailed Description

Shared primitives for CRACEN software implementation workarounds.

Shared primitives for CRACEN software implementation.

Provides AES-ECB block encrypt/decrypt, big-endian counter increment, and big-endian value encoding used across the software implementations.

Note

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