/* The PK wrappers need pk_write functions to format RSA key objects
* when they are dispatching to the PSA API. This happens under USE_PSA_CRYPTO,
* and also even without USE_PSA_CRYPTO for mbedtls_pk_sign_ext().
* PSA crypto also needs pk_write to export RSA keys (otherwise the build
* goes through but psa_export_key() and psa_export_public_key() fail on
* RSA keys), and pk_parse to work with RSA keys in almost any way.
