Excerpt: # TODO: Replace this Python implementation with a Rust/WASM module for critical cryptographic operations.
Intent: Enhance security and performance by moving critical crypto operations to a compiled Rust/WASM module to avoid Python memory management issues.
Effort: Large
Risk: High
Next Step: Research Rust bindings for Python (PyO3) or WASM integration strategies compatible with the current environment.
Note: Security-sensitive -> human review required.
