Function Documentation

int base64_decode	(	unsigned char *	dst,
		int *	dlen,
		unsigned char *	src,
		int	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, XYSSL_ERR_BASE64_BUFFER_TOO_SMALL, or XYSSL_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

int base64_encode	(	unsigned char *	dst,
		int *	dlen,
		unsigned char *	src,
		int	slen
	)

Encode a buffer into base64 format.

Parameters:

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

Returns:

0 if successful, or XYSSL_ERR_BASE64_BUFFER_TOO_SMALL. *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

int base64_self_test

(

int

verbose

)

Checkup routine.

Returns:
