opened on Aug 30, 2026

Contexto & Requisitos

Expandir a capacidade do \�nvguard\ para alem da correspondencia de nomes de arquivos, analisando o conteudo de arquivos modificados em busca de alta entropia de Shannon (chaves criptograficas, hashes, tokens aleatorios).

Tarefas

  • Implementar calculo de Shannon Entropy em Go para sequencias de caracteres alfanumericos e base64/hex.
  • Definir limiares (thresholds) calibrados para minimizar falsos positivos em arquivos comuns.
  • Garantir conformidade com a regra de seguranca do envguard: nunca imprimir ou expor os valores sensiveis nos logs/relatorios.
  • Suportar exclusao de arquivos binarios e arquivos de lock (\go.sum, \package-lock.json, etc.).
  • Adicionar testes unitarios com amostras de dados contendo strings aleatorias de alta entropia vs. texto convencional.
