SSL DOWNLOAD EXAMPLE

Description:
Download file from Web server via https.

Configuration:
Modify SERVER_HOST, SERVER_PORT and RESOURCE in example_ssl_download.c based on your SSL server.

Modify SSL_MAX_CONTENT_LEN in SSL config and configTOTAL_HEAP_SIZE in freertos config for large size file.
	If the transmitted fils size is larger than 16kbytes, SSL_MAX_CONTENT_LEN should be set to 16384.
	FreeRTOS heap may be increased for ssl buffer allocation.
	(ex. If using 16kbytes * 2 for ssl input/output buffer, heap should be increased from 60kbytes to 80kbytes.)
[config_rsa.h]
	#define SSL_MAX_CONTENT_LEN            16384
[FreeRTOSConfig.h]
	#define configTOTAL_HEAP_SIZE          ( ( size_t ) ( 80 * 1024 ) )

[platform_opts.h]
