@ -939,21 +939,10 @@ int mbedtls_rsa_rsassa_pss_sign_ext( mbedtls_rsa_context *ctx,
* the key size in bytes), this function returns
* #MBEDTLS_ERR_RSA_BAD_INPUT_DATA.
*
* \deprecated It is deprecated and discouraged to call this function
* in #MBEDTLS_RSA_PUBLIC mode. Future versions of the library
* are likely to remove the \p mode argument and have it
* implicitly set to #MBEDTLS_RSA_PRIVATE.
*
* \note Alternative implementations of RSA need not support
* mode being set to #MBEDTLS_RSA_PUBLIC and might instead
* return #MBEDTLS_ERR_PLATFORM_FEATURE_UNSUPPORTED.
*
* \param ctx The initialized RSA context to use.
* \param f_rng The RNG function. It must not be \c NULL.
* \param p_rng The RNG context to be passed to \p f_rng. This may be \c NULL
* if \p f_rng doesn't need a context argument.
* \param mode The mode of operation. This must be either
* #MBEDTLS_RSA_PRIVATE or #MBEDTLS_RSA_PUBLIC (deprecated).
* \param md_alg The message-digest algorithm used to hash the original data.
* Use #MBEDTLS_MD_NONE for signing raw data.
* \param hashlen The length of the message digest.
