While cryptography can still be a controversial topic in the programming community, Java has weathered that storm and provides a rich set of APIs that allow you, the developer, to effectively include cryptography in applications-if you know how. This book teaches you how. Chapters one through five cover the architecture of the JCE and JCA, symmetric and asymmetric key encryption in Java, message authentication codes, and how to create Java implementations with the API provided by the Bouncy Castle ASN.1 packages, all with plenty of examples. Building on that foundation, the second half of the book takes you into higher-level topics, enabling you to create and implement secure Java applications and make use of standard protocols such as CMS, SSL, and S/MIME.-While cryptography can still be a controversial topic in the programming community, Java has weathered that storm and provides a rich set of APIs that allow you, the developer, to effectively include cryptography in application

CH372 是一个USB 总线的通用设备接口芯片，是CH371的升级产品，是CH375芯片的功能简化版。在本地端，CH372 具有8 位数据总线和读、写、片选控制线以及中断输出，可以方便地挂接到单片机/DSP/MCU/MPU等控制器的系统总线上；在计算机系统中，CH372 的配套软件提供了简洁易用的操作接口，与本地端的单片机通讯就如同读写文件。 　　CH372 内置了USB 通讯中的底层协议，具有省事的内置固件模式和灵活的外置固件模式。在内置固件模式下，CH372自动处理默认端点0 的所有事务，本地端单片机只要负责数据交换，所以单片机程序非常简洁。在外置固件模式下，由外部单片机根据需要自行处理各种USB 请求，从而可以实现符合各种USB 类规范的设备。-err
