The code in basMD5.bas contains an implementation of the MD5 algorithm in VB6/VBA (zipped 6 kB). (VBA users should delete the first line with Attribute VB_Name in it.) This code is relatively slow. VB is not the best language to implement this algori

Java code for multi-layer/multi-level image encryption. At first level, effectively encrypts the image. At second level, re-encrypt the encrypted image. Little hard to understand. Have patience when reading the code (an honest advise for java beginne

一，产生密钥（算法实现可参照文档后的<附件1>KeyGeN.asp） 与<附件1>不同的是，实际要求密钥存放在字符串接受方数据库表KeyPool中，表结构如下： 1，personalID{主码} 2，secret_key{密钥，数据类型最好用text，与实际代码密钥生成长度有关} 3，serverTime{密钥生成时间，用以检验密钥是否失效} 接受方发现密钥失效，则拒绝验证 二，字符串加密（算法实现可参照文档后的<附
