模仿CA颁发证书模式，模拟证书颁发与认证。并假设Alice给Bob发送加密后的文档及文档的签名，Bob验证Alice证书的正确性和加密文档的正确性并最终解密文档。执行顺序为CA_Key-->CA-->Alice-->拷贝Alice的证书和加密文档给Bob-->Bob-Imitation of the CA that issued the certificate mode, analog certification and certification. And assume

CFCA认证中心javacard CA源码，已通过验证，包括Keypare生成，加解密/签名/验签-CFCA javacard CA sourcecode ，including Keypare Generation/encryption/decryption/sign/verify

安全通信引擎客户端，主要C++程序开发，主要进行数据加密，证书认证-client CA

加解密实现通信信息的保密功能，CA的认证系统很好用，-Encryption communication information confidential function, CA authentication system useful, thank you
