SHA2CC26X1.h File Reference

Detailed Description

SHA2 driver implementation for the CC26X1 family.

============================================================================

This file should only be included in the board file to fill the SHA2_config struct.

The CC26X1 family does not have a dedicated hardware crypto accelerator. As a result, there are several limitations and advantages over accelerator based implementations.

Limitations

• Asynchronously canceling an operation is not possible. The APIs will always run to completion.
• Invoking driver APIs from multiple contexts at the same time using the same handle is not permitted or guarded against.

Advantages

• Since this is a software implementation that uses dependency injection, it is possible for multiple clients to simultaneously invoke driver APIs with their respective handles.

Supported Digest Sizes

The driver is built on top of a SHA256 software implementation stored in ROM. As a result, digest sizes other than 256 bits are not supported with this driver.

SHA2_HashTypes Supported
SHA2_HASH_TYPE_256
