非对称密码技术的实现

（1）公私钥生成函数，加密/解密函数；

（2）利用公钥加密特定文件，并用私钥进行解密；反过来，再利用私钥加密特定文件，并用公钥进行解密。-Achieve asymmetric cryptographic techniques

(1) The public and private key generation functions, encryption/decryption functions

(2) the use of public key cryptography specific files, and use the private key to decrypt　in turn, re-use the private key to encrypt specific files, and use the public key to decrypt it.
