Tb4b4b4<Tff7b72pTb4b4b4>Reticulumには、すべての必要なプリミティブの純粋なPythonによる完全な実装も含まれています。Reticulumが開始されるときにシステムにOpenSSL＆PyCAが利用できない場合、Reticulumは代わりに内部の純粋なPythonプリミティブを使用します。これの取り決めの一因はパフォーマンスであり、OpenSSLバックエンドが非常に速いことです。しかし、最も重要な結果は、OpenSSLと同じくらいの精査、テスト、およびレビューを受けていないプリミティブを使用することによるセキュリティの潜在的な損失です。Tb4b4b4<Tb4b4b4/Tff7b72pTb4b4b4>

Tb4b4b4<Tff7b72pTb4b4b4>内部の純粋なPythonプリミティブを使用したい場合は、このリスクが許容できるかどうかを検討し、よく理解した上で情報を得ることがTb4b4b4<Tff7b72strongTb4b4b4>強くお勧めTb4b4b4<Tb4b4b4/Tff7b72strongTb4b4b4>されます。Tb4b4b4<Tb4b4b4/Tff7b72pTb4b4b4>

Tb4b4b4<Tff7b72pTb4b4b4>Reticulumは比較的新しいソフトウェアであり、それに準じて考えるべきです。暗号化のベストプラクティスを非常に重視して構築されていますが、外部からのセキュリティ監査はまだ行われておらず、プライバシーやセキュリティを崩壊させる可能性があります。協力したり、監査をスポンサーしたりしたい場合は、どうぞお知らせください。Tb4b4b4<Tb4b4b4/Tff7b72pTb4b4b4>
