用JAVA语言实现DES算法。通过文件读取进行加密，密码由客户自行输入(JAVA language used DES algorithm. Read through the document is encrypted, the password input by the customer on its own)

是des的一种算法，被称为计数器模式（counter mode）(Is a des algorithm, known as the Counter mode (counter mode))

此为国外转载函数，可将任意字符转换为md5 16为字符加密形式，而且为不可逆转换。-reproduced here for foreign functions, arbitrary characters can be converted to 16 md5 encrypted form of characters, but also to irreversible change.

文件加密使用,可以实现对PC上文件进行加密解密功能(document encryption use, the PC can be achieved on the document encryption and decryption functions)

Crypto api 使用实例，可以学习的例子-Crypto api to use examples, you can learn from examples

java写的椭圆曲线加密(ECC)算法源码-java writes the elliptic curve encryption (ECC) calculates the law origin code

MD5加密算法，实现报文认证！！运算速度快，兼容性好(MD5 encryption algorithm, message authentication realize! ! Computing speed, better compatibility)

用C编程获取WPS的文件密码-C programming WPS access to the password file

base64解码 -base64 decoding base64 decoding

vb写的DES源码，复制到Visual Basic 6.0 中即可使用。-vb source code written by DES, copy to the Visual Basic 6.0, can be used.
