Chave criptográfica embutida no código

Armazenar chaves criptográficas diretamente no código-fonte ou binário da aplicação expõe-as a qualquer pessoa com acesso ao repositório, arquivo compilado ou descompilado. Uma chave descoberta invalida toda a segurança que ela deveria proteger — tanto para cifração quanto para autenticação ou assinatura.

Exemplo

Uma API que usa a string `const API_KEY = '5f8e2b9c4d1a7x3q'` hardcoded no arquivo index.js. Qualquer dev que clone o repositório, ou um atacante que decompile o app mobile, obtém a chave e pode fazer requisições como se fosse a aplicação legítima.

Como mitigar

Armazene chaves em variáveis de ambiente, cofres de secrets (AWS Secrets Manager, HashiCorp Vault, Azure Key Vault) ou arquivos de configuração fora do versionamento (adicionados ao .gitignore). Nunca commite credenciais no git; use ferramentas como pre-commit hooks para detectar e bloquear antes do envio.
