Function Documentation

uint32_t DecodeBase64	(	uint8_t *	dest,
		const uint8_t *	src,
		uint32_t	len,
		int	strict
	)

Decodes a base64-encoded string buffer into an ascii-encoded byte buffer.

Parameters

dest	The destination byte buffer
src	The source string
len	The length of the source string
strict	If set file on invalid byte, otherwise return what has been decoded.

Returns

Number of bytes decoded, or 0 if no data is decoded or it fails
