#define POLARSSL_ERR_BASE64_BUFFER_TOO_SMALL   0x0010

#define POLARSSL_ERR_BASE64_INVALID_CHARACTER   0x0012

int base64_decode	(	unsigned char *	dst,
		int *	dlen,
		const 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, 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

int base64_encode	(	unsigned char *	dst,
		int *	dlen,
		const 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 POLARSSL_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

0 if successful, or 1 if the test failed
