+ * \note ECDSA & RSA keys are supported.
+ * For both key types, signing with the specified hash

+ * The RSA key supports RSA-PSS signing with the specified
+ * hash with the PK EXT API.
+ * In addition, the ECDSA key is also allowed for ECDH key
+ * agreement derivation operation using the PSA API.

- * \param pk Input: the EC key to import to a PSA key.

* Output: a PK context wrapping that PSA key.
* \param key Output: a PSA key identifier.
