base64_decode()

size_t base64_decode	(	const unsigned char *	src,
		size_t	len,
		unsigned char *	out,
		size_t	out_len
	)

base64_decode - Base64 decode @src: Data to be decoded @len: Length of the data to be decoded @out: Output buffer to decode into @out_len: Length of output buffer Returns: Length of encoded data, or 0 on failure

base64_encode()

size_t base64_encode	(	const unsigned char *	src,
		size_t	len,
		unsigned char *	out,
		size_t	out_len
	)

base64_encode - Base64 encode @src: Data to be encoded @len: Length of the data to be encoded @out: output uffer @out_len: length of output buffer Returns: Number of actual bytes encoded into the buffer or 0 on failure

Output buffer is nul terminated to make it easier to use as a C string. The nul terminator is * not included in the return length.
