rsa

一个DES加解密程序，有兴趣的可以下来看看。(A program about DES)

图像加密算法,很不错的东东。包含图像基本的加密算法(image cryption)

MD5加密算法，可以加密包含二进制数据的数据块，生成16字节MD5加密数据。(MD5 encryption algorithm to encrypt data blocks that contain binary data, generates a 16-byte MD5 encrypted data.)

说明：  ECC实现加密解密功能，系统参数的生成！(ECC to achieve encryption and decryption functions, system parameter generation!)

使用DES算法；可以指定使用DES、2DES或者3DES算法；可以对任意的文件进行加密和解密，加密后文件扩展名为.des，可以指定使用ECB,CBC,CFB,OFB,CTR的任意一种模式； (The use of DES algorithm can specify the use of DES, 2DES or 3DES algorithm can arbitrary file encryption and decryption, encryption, named after the file extension. Des, you can specify the use of ECB, CBC, CFB, OFB, CTR arbitrary a model )

AES加密，并完成基于AES的CAMC操作(AES encryption and the AES operation is completed based on CAMC)

说明：  使用维吉尼亚密码进行控制台编程，实现对英文文本文件的加解密！(Virginia password using the console program, to achieve the English version of the document encryption and decryption!)

基于国密算法SM3实现HMAC，输入密钥和消息，可产生HASH验证码，C环境下调试成功(Based on the countries close algorithm realization SM3 HMAC, input key and news, can produce HASH verification code, C environment debugging success)

实现维吉尼亚密码，用键盘接收明文和密钥，屏幕打印密文和解密后的明文。 可以实现：大小写敏感，明文小写则密文大写，明文大写则密文小写输出，注意输入的健壮性控制，明文字符超出字符集后保留原文(Virginia to achieve the password, use the keyboard to receive the plaintext and the key, the screen printing ciphertext and the decrypted plaintext. Can be achieved: case sensitive, then the ciphertext plaintext lowercase uppercase, lowercase plaintext ciphertext output is capital, pay attention to the robustness of the control input, plaintext characters out retain the original character set)

用于实现文本串的加密解密功能，程序自带密匙(Text string used to implement the encryption and decryption functions, comes with key program)
