Since mbedtls 2.7.0 new digest functions were introduced with a "_ret" suffix to allow the functions to return an error message (eg, if the underlying hardware acceleration failed). These new functions must be used instead of the old ones to prevent deprecation warnings, or link errors for missing functions, depending on the mbedtls configuration.
