VB实现文件的异或加密算法探索

VB File Exclusive-or Encryption Algorithm Exploration

本文通过VB二进制文件,利用计算机时钟秒数作为随机数发生器程序的随机种子数,所产生的字节随机数密钥与文件二进制数据进行异或运算,这样给出的文件异或加密的VB实现,由于对中文字符使用了高低字节双密钥数,因此,适用于任何中文与英文的混合文档文件,具有安全性高,通用性强的特点,对VB应用开发具有参考意义。进一步地,在密文文档的基础上,再逐级反复使用相同的异或加密算法,达到更高安全的加密要求。

Paper through VB bit file, using computer clock seconds number as random number generator program of random seed number, by produced of byte random number key and file bit data for Xor operation, such to out of file Xor encryption of VB achieved, due to on in the text breaks using has level byte double key number, so, applies any Chinese and English of mixed document file, has securiW high, versatility strong of features, on VB application development has reference meaning. Further, the redaction document based on step by step again and again using the same XOR encryption algorithms achieve higher securiW encryption requirements.
