Decode a base64 encoded string.

Decode a base64 encoded string. The result must deleted using release.

Name	Type	Default	Description
Return	char*		New created char* string with the decoded input string. Must released using release!
txt	char*	-	any base64 encoeded char* string
binary	int	0	Decode binary data? When this parameter is set to 1, the result contains zeros and the terminating zero is omitted. In this case you should make use of the output parameter oLength to determine the length of the result buffer.
oLength	int *	0	Result length of the decoded data. Important when decoding binary data where strlen is not usable.
useSOAPDecoder	int	0	You will hardly ever need the parameter, but just in case: If the parameter has a value other than 0, exactly the same decoder is used as in SOAP. In Illustrator, the parameter is ignored and the default decoding method is always used.

Encoding the current text and decoding this result must be equal.

int main ()
{
    String			str	= string::alloc ();
    char		*	enc	= 0;
    char		*	dec	= 0;

    textmodel::gettext (str);

    enc	= encode_base64 (string::get (str));
    dec	= decode_base64 (enc);

    showmessage ("%s\n\n%s\n\n%d", enc, dec, strcmp (string::get (str), dec));

    release (enc);
    release (dec);

    return 0;
}

Write the content of the current textmodel base64 encoded to a file. After reading and decoding this files boths strings must be equal. Take care to use a big enoug buffer while reading or read and decoded using a loop.

int main ()
{
    String			str	= string::alloc ();
    char		*	enc	= 0;
    char		*	dec	= 0;
    char			buf	[3001];
    int			fi	= 0;

    textmodel::gettext (str);

    // Encode to file
    enc	= encode_base64 (string::get (str));

    fi 	= file::open ("$DESKTOP/txt.txt", "w");
    file::write (fi, enc);
    file::close (fi);

    // Decode from file
    fi 	= file::open ("$DESKTOP/txt.txt", "r");
    file::read (fi, buf, 3000);
    file::close (fi);
    dec	= decode_base64 (buf);

    showmessage ("%s\n\n%s\n\n%d", enc, dec, strcmp (string::get (str), dec));

    release (enc);
    release (dec);

    return 0;
}
