Tb4b4b4<Tff7b72pTb4b4b4>Reticulum também incluí a implementação completa de todos os primitivos necessários em Python puro. Se o OpenSSL Te6edf3& PyCA não estão disponíveis no sistema que o Reticulum é iniciado, Reticulum vai utilizar os primitivos internos. A consequência trivial disso é o desempenho, com a biblioteca OpenSSL sendo mais rápida. A consequência mais importante no entanto, é a potencial perda de segurança por utilizar primitivos que não possuem o mesmo nível de suporte, teste e revisão que o OpenSSL.Tb4b4b4<Tb4b4b4/Tff7b72pTb4b4b4>
Tb4b4b4<Tff7b72pTb4b4b4>Se você quer utilizar primitivos internos em Python, é aconselhável que você entenda os riscos envolvidos, e tome uma decisão informada conforme os ricos são aceitáveis para você.Tb4b4b4<Tb4b4b4/Tff7b72pTb4b4b4>
Tb4b4b4<Tff7b72pTb4b4b4>Reticulum é um software relativamente jovem, e deve ser considerado como tal. Enquanto ele é desenvolvido com as melhores práticas de criptografia em mente, ainda não foi auditado externamente, e pode haver bugs para segurança e privacidade.
