I want to evaluate cryptographic algorithms on the boot loader before Linux starts up.

We plan to include evaluation software in ARM Trusted Firmware (bl31-h3ulcb).

ARM Trusted Firmware has no encryption algorithm, so we are considering using a library in OP-TEE (tee-h3ulcb).

For example, in evaluating signature verification using RSA, the following processing is considered necessary.

・ Register the public key and secret key.

・ And generates a hash value of the evaluation target data. (For example SHA 256)

・ Generate a signature by encrypting the hash value with the secret key.

・ Generate a hash value by decrypting the signature with the public key.

Among these processes, I do not know how to register the public key and secret key to OP-TEE.

Please tell me what kind of processing can be realized from ARM Trusted Firmware.
