/**
 * \file psa/crypto_adjust_config_key_pair_types.h
 * \brief Adjust PSA configuration for key pair types.
 *
 * See docs/proposed/psa-conditional-inclusion-c.md.
 * - Support non-basic operations in a keypair type implicitly enables basic
 *   support for that keypair type.
 * - Support for a keypair type implicitly enables the corresponding public
 *   key type.
 * - Basic support for a keypair type implicilty enables import/export support
 *   for that keypair type. Warning: this is implementation-specific (mainly
 *   for the benefit of testing) and may change in the future!
