Detailed Description

Encode/Decode a stream of ACEXML_Chars according to Base64 encoding.

This class provides methods to encode or decode a stream of ACEXML_Chars to/from Base64 encoding. It doesn't convert the input stream to a canonical form before encoding.

ACEXML_Char * ACEXML_Base64::decode	(	const ACEXML_Char *	input,
		size_t *	output_len
	)			[static]

Decodes a stream of Base64 to octets data

Parameters:

	input	Encoded Base64 data in ACEXML_Char stream.
	output_len	Length of the binary ACEXML_Char stream.

Returns:

Binary data in ACEXML_Char stream or NULL if input data cannot be encoded.

ACEXML_Char * ACEXML_Base64::encode	(	const ACEXML_Char *	input,
		size_t *	output_len
	)			[static]

Encodes a stream of octets to Base64 data

Parameters:

	input	Binary data in ACEXML_Char stream.
	output_len	Length of the encoded Base64 ACEXML_Char stream.

Returns:

Encoded Base64 data in ACEXML_Char stream or NULL if input data cannot be encoded.
