- ``KEY_ALG``: This build flag enables the user to select the algorithm to be
used for generating the PKCS keys and subsequent signing of the certificate.
- It accepts 3 values: ``rsa``, ``rsa_1_5`` and ``ecdsa``. The option
- ``rsa_1_5`` is the legacy PKCS#1 RSA 1.5 algorithm which is not TBBR
- compliant and is retained only for compatibility. The default value of this
- flag is ``rsa`` which is the TBBR compliant PKCS#1 RSA 2.1 scheme.

- ``KEY_SIZE``: This build flag enables the user to select the key size for
the algorithm specified by ``KEY_ALG``. The valid values for ``KEY_SIZE``
depend on the chosen algorithm and the cryptographic module.
