Function Documentation

int base64_decode	(	unsigned char *	dst,
		size_t *	dlen,
		const unsigned char *	src,
		size_t	slen
	)

Decode a base64-formatted buffer.

Parameters:

dst	destination buffer
dlen	size of the buffer
src	source buffer
slen	amount of data to be decoded

Returns:

0 if successful, POLARSSL_ERR_BASE64_BUFFER_TOO_SMALL, or POLARSSL_ERR_BASE64_INVALID_DATA if the input data is not correct. *dlen is always updated to reflect the amount of data that has (or would have) been written.

Note:

Call this function with *dlen = 0 to obtain the required buffer size in *dlen
