Function Documentation

BEECRYPTAPI char* b64crc	(	const unsigned char *	data,
		size_t	ns
	)

Encode crc of binary input data into 5 bytes of base64 output.

Parameters:

	data	binary data
	ns	no. bytes of binary data

Returns:

(malloc'd) base64 string

BEECRYPTAPI memchunk* b64dec

(

const char *

)

BEECRYPTAPI int b64decode	(	const char *	s,
		void **	datap,
		size_t *	lenp
	)

Decode chunks of 4 bytes of base64 input into 3 bytes of binary output.

Parameters:

s

base64 string

Return values:

	datap	address of (malloc'd) binary data
	lenp	address of no. bytes of binary data

Returns:

0 on success, 1: s == NULL, 2: bad length, 3: bad char

BEECRYPTAPI char* b64enc

(

const memchunk *

)

BEECRYPTAPI char* b64encode	(	const void *	data,
		size_t	ns
	)

Encode chunks of 3 bytes of binary input into 4 bytes of base64 output.

Parameters:

	data	binary data
	ns	no. bytes of data (0 uses strlen(data))

Returns:

(malloc'd) base64 string
