High level tests for the kyber library that verify serialization and deserialization compatibility across different versions.

Overview

This repository contains tests that ensure cross-version compatibility of the kyber cryptographic library. The tests verify that:

• Scalars and Points serialize to the same bytes in v3 and v4
• Data serialized by one version can be deserialized by the other
• Cryptographic operations (addition, multiplication, etc.) produce the same results
• Schnorr signatures are compatible across versions
• Diffie-Hellman key exchange works across versions

Running Tests

Tested Versions

• kyber v3.1.0
• kyber v4.0.1-alpha.1 git

Test Coverage

Serialization Tests (serialization_test.go)
