In this program I am trying to send key shares though UDP broadcast to the client(s). The issue I'm facing is with encoding of strings and bytes into one message, there are number of errors are produced.
I would like to send from the server to the client a random ID and a key share, which include index (integer) and share (16-bytes string). I have added ":" between id, index and share to be able to manage it at the client later (by splitting the message into parts).
I have tried converting everything into string, such as:
message = (str(id) + ":" + str(index) + ":").encode('utf-16') + str(share, 'utf-16'). But this causing issues in key reconstruction at the client, where the key share should be a byte string and it looks like
Then I have tried encoding id and index to utf-16 and sending a message to the client, and then decode it, but this does not let me reconstruct the key and I'm getting an error:
ValueError: The encoded value must be an integer or a 16 byte string.
When I decode at the client, the data looks like this:
f91f7e52-865d-49bc-bb45-ad80255e9ef9:5:륪賛缦蜆䦘ﱧ䨞뗶. However, some shares after decoding do not contain dilimiter and thus not being able to split.
Is there a way the server can send all the following data in one message (id, index, share), so that it can be separated correctly at the client?
The desired output at server would be (id = string, index = int, share = 16-byte string):...

The UUID can be encoded as 16 bytes value, the integer e.g. as 4 bytes and and
share has a length of 16 bytes. Therefore the data can be simply concatenated without delimiter and separated by their lengths, e.g.:

You can use secretsharing like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the secretsharing component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
