Access an algorithm specific field
If the field is not known for this algorithm, an Invalid_Argument is thrown. The interpretation of the result requires knowledge of which algorithm is involved. For instance for RSA "p" represents one of the secret primes, while for DSA "p" is the public prime.
Some algorithms may not implement this method at all.
This is primarily used to implement the FFI botan_pubkey_get_field and botan_privkey_get_field functions.
