The question here doesn't really make any sense. You can store anything you want in the value field (regardless of the type, although it's well-behaved to set it to Type.BINARY). No transformation is needed, just put raw data in the string. In particular, "ABC" is perfectly reasonable. > { "key": "TEST_BINARY(A5)", "t": Type.BINARY, "value": "a5" }, # How transform this to save it as Binary value? The same thing, but I guess perhaps you mean "how do I store the byte 0xa5 here?" in which case you can write "\xa5", using a standard Python escape sequence: http://docs.python.org/release/2.5.2/ref/strings.html Basically you need to investigate what Windows is expecting in each field (and it differs by field and by context) and generate whatever happens to work on Windows. Which is hard for a general-purpose graphical registry editor, but the registry is a huge technical mess, news at 11. Rich.
