* (1) Parameter-generating helpers. These are:
* - mbedtls_rsa_deduce_primes
* - mbedtls_rsa_deduce_private_exponent
* - mbedtls_rsa_deduce_crt
* Each of these functions takes a set of core RSA parameters and
* generates some other, or CRT related parameters.
*
* (2) Parameter-checking helpers. These are:
