Detailed Description

Utility class to encoding and decoding binary data to base64 string suitable for storing in text file.

Base64 is an encoding method which converts bit values into ASCII text (no control characters).

Constructor & Destructor Documentation

MAKLogger::DtBase64Data::DtBase64Data ( const DtString & base64String )

Create base 64 data from a string.

The data input is assumed to be base64 encoded data.

MAKLogger::DtBase64Data::DtBase64Data	(	char *	data,
		size_t	len
	)

Create base 64 data from binary.

The object takes ownership of the memory pointed to by data.

static char* MAKLogger::DtBase64Data::decode	(	const DtString &	,
		size_t &	len
	)		`[static]`

decode a base64 string into binary data.

Exceptions:

DtInvalidInput if stringContains non-base64 characters.
