非对称密码技术的实现

（1）熟悉RSA相关函数（公私钥生成函数，加密/解密函数）；

（2）利用公钥加密特定文件（test-1.txt），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。对比解密后的文件与原始文件是否一致。

-Achieve asymmetric cryptographic techniques (1) be familiar with RSA-related functions (public and private key generation functions, encryption/decryption function)　(2) the use of public key cryptography specific file (test-1.txt), and with the private key to decrypt　turn , and then use the private key to encrypt specific files, and use the public key to decrypt it. Comparative decrypted file if the original files are consistent.
