さまざまなタスクを実行するさまざまなプロセスを作成しています。それらの 1 つだけに、PyCrypto オブジェクトを作成するセキュリティ モジュールがあります。したがって、私のプログラムが起動し、さまざまなプロセスが作成され、メッセージを処理するプロセスがセキュリティモジュールを使用して復号化し、次のエラーが発生します。
firstSymKeybin = self.cipher.decrypt(encFirstSymKeybin, '')

AssertionError: PID check failed. RNG must be re-initialized after fork(). Hint: Try Random.atfork()
復号化は、プロセスから呼び出されていない場合、対話型でうまく機能します。
私のセキュリティ モジュールは次のようになります。
