Function Documentation

◆ fb_base64_decode()

char * fb_base64_decode	(	const char *	data,
		const char *	end_data,
		int *	length
	)

Decode some base-64 encoded data.

Parameters

data	The start of the data. Whitespace in data is ignored.
end_data	The end of the data.
length	The length of the decoded binary data.

Returns: A pointer to malloc'ed data blocked, or nullptr on error.

Warning: The returned data block must be freed.

◆ load_pem_thing()

char * load_pem_thing	(	const char *	filename,
		const char *	object_type,
		int *	length
	)

Extract a base 64 encoded, delimited data block from a PEM formatted file.

Parameters

filename	The file.
object_type	The type of block to extract.
length	The length of the resulting data block.

Returns: A pointer to the extracted data blocked, or nullptr on error.

Warning: The returned data block must be freed.
