+ *
+ * This function creates a PK context which wraps a PSA key. The PSA wrapped
+ * key must be an EC or RSA key pair (DH is not suported in the PK module).
+ *
+ * Under the hood PSA functions will be used to perform the required
+ * operations and, based on the key type, used algorithms will be:
+ * * EC:
+ *     * verify, verify_ext, sign, sign_ext: ECDSA.
+ * * RSA:
+ *     * sign, decrypt: use the primary algorithm in the wrapped PSA key;
+ *     * sign_ext: RSA PSS if the pk_type is #MBEDTLS_PK_RSASSA_PSS, otherwise
+ *       it falls back to the sign() case;
+ *     * verify, verify_ext, encrypt: not supported.
+ *
+ * In order for the above operations to succeed, the policy of the wrapped PSA
+ * key must allow the specified algorithm.
+ *
+ * Opaque PK contexts wrapping an EC keys also support \c mbedtls_pk_check_pair(),
+ * whereas RSA ones do not.
+ *
+ * \warning The PSA wrapped key must remain valid as long as the wrapping PK
+ *          context is in use, that is at least between the point this function
+ *          is called and the point mbedtls_pk_free() is called on this context.
