PSoC 6 MCU

New Contributor II

Hello -

Another PSoC 6 crypto library question.

This page: PSoC 6 Peripheral Driver Library: Client Functions describes a pair of ECDSA functions (Cy_Crypto_ECDSA_SignHash/Cy_Crypto_ECDSA_VerifyHash), but the PDL documentation (3.1.2) for my PSoC creator install makes no mention of it.

Is this similar to the RSA 4096 bit support (coming to PDL in the future, and only on newer chips)?

Yes, it will be. Note that we recommend developing applications using ModusToolbox for PSoC6 products. PSoC Creator supports only a few PSoC6 devices and the PDL is older when compared to the psoc6pdl packaged with ModusToolbox. The documentation you attached earlier in the interaction is of ModusToolbox psoc6pdl which has these APIs available.

But wrt to PDL of PSoC Creator, the ECDSA APIs will be made available in the newer releases.

Yes, currently ECDSA sign / verify / keygen functionality is implemented using direct Crypto core functions and is not available for client/server calls. This will be made available in the next release of the PDL.

Will the ECDSA functions be available for the CY8C6247BZI-D54 chip, or only on newer chips?
