xmpp_base64_encode()

char * xmpp_base64_encode	(	xmpp_ctx_t *	ctx,
		const unsigned char *	data,
		size_t	len
	)

Base64 encoding routine.

Returns an allocated string which must be freed with xmpp_free().

Parameters

ctx	a Strophe context
data	buffer to encode
len	size of the data buffer

Returns

an allocated null-terminated string or NULL on error

xmpp_base64_decode_str()

char * xmpp_base64_decode_str	(	xmpp_ctx_t *	ctx,
		const char *	base64,
		size_t	len
	)

Base64 decoding routine.

Returns an allocated string which must be freed with xmpp_free(). User calls this function when the result must be a string. When decoded buffer contains '\0' NULL is returned.

Parameters

ctx	a Strophe context
base64	encoded buffer
len	size of the buffer

Returns

an allocated null-terminated string or NULL on error

xmpp_base64_decode_bin()

void xmpp_base64_decode_bin	(	xmpp_ctx_t *	ctx,
		const char *	base64,
		size_t	len,
		unsigned char **	out,
		size_t *	outlen
	)

Base64 decoding routine.

Returns an allocated buffer which must be freed with xmpp_free().

Parameters

ctx	a Strophe context
base64	encoded buffer
len	size of the encoded buffer
out	allocated buffer is stored here
outlen	size of the allocated buffer

Note

on an error the *out will be NULL
