- * \deprecated     It is deprecated and discouraged to call this function
- *                 in #MBEDTLS_RSA_PRIVATE mode. Future versions of the library

- *
  * \param ctx      The initialized RSA public key context to use.
- * \param mode     The mode of operation. This must be either
- *                 #MBEDTLS_RSA_PUBLIC or #MBEDTLS_RSA_PRIVATE (deprecated).
  * \param md_alg   The message-digest algorithm used to hash the original data.

  * \param hashlen  The length of the message digest.
