aes256加密解密算法，256bit秘钥，配有例子 。(aes256 encrypt and decrypt)

程序采用当前最先进的Rijndael算法作为核心算法，带有可变块长和可变密钥长度的迭代块密码。块长和密钥长度可以分别指定成 128、192 或 256 位。多线程操作，保证加密时程序界面流畅，加密速度大约9M每秒。(Procedures using the most advanced as a core algorithm Rijndael algorithm with variable block length and variable key length of the iterative block password. Block length and key length can be specified as 128,192 or 256. Multi-threaded operation, to ensure smooth program interface encryption, encryption speed of about 9M per second.)

实现透明加密,驱动模型，文件过滤系统介绍(To achieve transparent encryption, drive model, document filtering system introduced)

使用dll，将vc下进行文件加解密的blowfish方法做成dll文件，从而在vc中调用，隐藏加解密的参变量。(Using dll, under the vc the blowfish file encryption method made dll file, so call in vc, the hidden variable encryption and decryption of the parameters.)

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.)

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)

加密文件夹,十分好用 使用visual basic环境编程(lock file)

PHP5.2 5.3 5.4等 zend加密代码解密(PHP5.2 5.3 5.4 Zend encryption code decryption)

DES( Data Encryption Standard)算法，于1977年得到美国政府的正式许可，是一种用56位密钥来加密64位数据的方法。虽然56位密钥的DES算法已经风光不在,而且常有用Des加密的明文被破译的报道,但是了解一下昔日美国的标准加密算法总是有益的,而且目前DES算法得到了广泛的应用,在某些场合,她仍然发挥着余热.（如：UNIX的密码算法就是以DES算法为基础的）。将其修改为三重DES也能抵抗破解。下面是关于如何实现DES算法的语言性描述：(DES ( Data Encryption Standard ) algorithm, in 1977 the U.S. government s official permission , is a 56 -bit key to encrypt 64 data . 56 keys of the DES algorithm scenery is not , and often with Des encryption expressly decipher reported , but look at the old standard encryption algorithm is always useful , but the DES algorithm has been widely used in a some occasions , she still plays a waste heat . (such as : UNIX password algorithm is DES algorithm -based ) . To modify the Triple DES is also resistant to cracking . The following is a description language on how to achieve the DES algorithm : )
