Signature generation with RSA-4096 keys not configurable on RA8 devices in FSP v5.3.0 #352

Closed michaelthomasj closed 4 months ago

michaelthomasj commented 5 months ago

Issue

Signature generation using imported or generated RSA-4096 keys cannot be enabled on RA8 devices in FSP v5.3.0 via the PSA Crypto module configurator.

Workaround

To enable signature generation with RSA-4096 keys, add the define RM_PSA_CRYPTO_CFG_RSA4K_SIGNING_ENABLED to the project and set it to 1. image

This is being internally tracked using FSPRA-2880 and will be fixed in FSP 5.3.0.
