Detailed Description

Struct containing the parameters required for MAC operations.

Field Documentation

§ input

uint8_t* HSMBareMetal_MACOperationStruct::input

Sign: Pointer to the input message to be authenticated.
- Verify: Pointer to the input message to be verified.

§ inputLength

size_t HSMBareMetal_MACOperationStruct::inputLength

Length of the input message in bytes. May be zero for CMAC but must be non-zero for CBC-MAC. See function descriptions for further restrictions. Max length supported may be limited depending on the return behavior.

§ keyAssetID

uint32_t HSMBareMetal_MACOperationStruct::keyAssetID

The asset ID for the key in AssetStore

§ mac

uint8_t* HSMBareMetal_MACOperationStruct::mac

Sign: Pointer to the output buffer to write the generated MAC. Buffer size must be at least equal to macLength.
- Verify: Pointer to the input MAC to be used for verification.

§ macLength

size_t HSMBareMetal_MACOperationStruct::macLength

Length of the MAC in bytes. Must be <= 16. A length of < 8 is not recommended and should severely restrict MAC recomputation attempts. See appendix A of NIST SP800-38b for more information.
