define Package/libmbedtls/config
config LIBMBEDTLS_DEBUG_C
	depends on PACKAGE_libmbedtls
	bool "Enable debug functions"
	default n
	help
	 This option enables mbedtls library's debug functions.

	 It increases the uncompressed libmbedtls binary size
	 by around 60 KiB (for an ARMv5 platform).

	 Usually, you don't need this, so don't select this if you're unsure.

config LIBMBEDTLS_HKDF_C
	depends on PACKAGE_libmbedtls
	bool "Enable the HKDF algorithm (RFC 5869)"
	default n
	help
	 This option adds support for the Hashed Message Authentication Code
	 (HMAC)-based key derivation function (HKDF).
