iMX8QXP CAAM - Red Blobs

MooTacos — Wed, 02 Oct 2024 05:36:37 GMT

Hi,

I'm looking for some information on generating Red Blobs for general data storage. The Security Reference Manual seems to indicate its possible.

I can only find examples for generating Black Key Blobs (https://github.com/nxp-imx/keyctl_caam)

Is there a device driver similar to "caam-keygen" (https://github.com/nxp-imx/linux-imx/blob/lf-6.6.y/drivers/crypto/caam/caamkeygen.c). That can be used for general blob encapsulation/decapitation?

if I write a driver to interface with "blob_gen.c" will this work for general red blobs?(https://github.com/nxp-imx/linux-imx/blob/lf-6.6.y/drivers/crypto/caam/blob_gen.c)
