- Fix ElGamalEncryption to generate keypair on initialization and provide public_key_bytes property with proper "p:g:h" UTF-8 format - Add ElGamal alias for backward compatibility with imports - Improve frontend error handling with detailed base64 decode error messages - Update .gitignore to specifically ignore backend/lib/ and backend/lib64/ instead of all lib directories, preserving frontend node_modules-style lib/ This fixes the "Invalid public key format" error that was preventing vote submission during testing. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
