Create a base64 coded string of a given char* string.

Create a base64 coded string of a given char* string. The result must deleted using release.

Name	Type	Default	Description
Return	char*		New created char* string with the base64 coded input string. Must released using release!
txt	char*	-	any char* string
bufferLength	int	-1	Length of the input buffer. When this parameter is smaller or equal to 0, the length of the input buffer is determined automatically (only works for zero-terminated char* buffers!). When you want to encode binary data, provide the length of the input buffer here.

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;
}
