config OPENSSL_DEBUG
    bool "Enable OpenSSL debugging"
    default n
    help
       Enable OpenSSL debugging function.

       If the option is enabled, "SSL_DEBUG" works.

config OPENSSL_DEBUG_LEVEL
   int "OpenSSL debugging level"
   default 0
   range 0 255
   depends on OPENSSL_DEBUG
   help
       OpenSSL debugging level.

       Only function whose debugging level is higher than "OPENSSL_DEBUG_LEVEL" works.

       For example:
           If OPENSSL_DEBUG_LEVEL = 2, you use function "SSL_DEBUG(1, "malloc failed")". Because 1 < 2, it will not print.

config OPENSSL_LOWLEVEL_DEBUG
    bool "Enable OpenSSL low-level module debugging"
    default n
    depends on OPENSSL_DEBUG
    select MBEDTLS_DEBUG
    help
       If the option is enabled, low-level module debugging function of OpenSSL is enabled, e.g. mbedtls internal debugging function.

choice OPENSSL_ASSERT
    prompt "Select OpenSSL assert function"
    default CONFIG_OPENSSL_ASSERT_EXIT
    help
        OpenSSL function needs "assert" function to check if input parameters are valid.

        If you want to use assert debugging function, "OPENSSL_DEBUG" should be enabled.

config OPENSSL_ASSERT_DO_NOTHING
    bool "Do nothing"
    help
        Do nothing and "SSL_ASSERT" does not work.

config OPENSSL_ASSERT_EXIT
    bool "Check and exit"
    help
        Enable assert exiting, it will check and return error code.

config OPENSSL_ASSERT_DEBUG
    bool "Show debugging message"
    depends on OPENSSL_DEBUG
    help
        Enable assert debugging, it will check and show debugging message.

config OPENSSL_ASSERT_DEBUG_EXIT
    bool "Show debugging message and exit"
    depends on OPENSSL_DEBUG
    help
        Enable assert debugging and exiting, it will check, show debugging message and return error code.

config OPENSSL_ASSERT_DEBUG_BLOCK
    bool "Show debugging message and block"
    depends on OPENSSL_DEBUG
    help
        Enable assert debugging and blocking, it will check, show debugging message and block by "while (1);".
