第三阶段:调用preload()方法装载系统资源,包括系统预加载类、Framework资源和openGL的资源。这样当程序被fork处理后,应用的进程内已经包含了这些系统资源,大大节省了应用的启动时间。 第四阶段:调用startSystemServer()方法启动SystemServer进程 第五阶段:调动runSelectLooper方法进入监听和接收消息的循环 ...
The JDK implementation of TLS 1.2 now uses a default Diffie Hellman keysize of 2048 bits when a TLS_DHE cipher suite is negotiated and either the client or server does not support FFDHE, which can negotiate a stronger keysize. The JDK TLS implementation supports FFDHE and it is enabled by...
* AES key size must be equal to 128, 192 or 256,but 192 and 256 bits may not be available * Blowfish key size must be multiple of 8, and can only range from 32 to 448 (inclusive) * RC2 key size must be between 40 and 1024 bits ...
