kandi X-RAY | secretsharing Summary

secretsharing is a Ruby library typically used in Security, Cryptography applications. secretsharing has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

A Ruby gem for sharing secrets using [Shamir’s Secret Sharing] which is an [information-theoretic] secure method to share secrets between trusted parties. Shamir’s Secret Sharing is an algorithm in cryptography created by Adi Shamir. It is a form of secret sharing, where a secret is divided into parts, giving each participant its own unique part, where some of the parts or all of them are needed in order to reconstruct the secret. Counting on all participants to combine together the secret might be impractical, and therefore sometimes the threshold scheme is used where any k of the total shares n are sufficient to reconstruct the original secret. k - 1 secret share holders can learn nothing about the secret, even when they combine their shares with others. Only once the k threshold of shares combined is reached will the original secret be revealed.

Python Sending String and Bytes over UDP in One Message

QUESTION

Python Sending String and Bytes over UDP in One Message

Asked 2022-Mar-20 at 17:20

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 b"b'\xff\xfej\xb9\xdb\x8c&\x7f\x06\x87\x98Ig\xfc\x1eJ\xf6\xb5'".

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.:
