access数据库加密有几法，但用“设置安全机智向导”加密最为牢靠，又如何访问这样的数据库呢-access database encryption with a few laws, but "to provide a safety witty guide" the most secure encryption, how to access such a database?

md5通用加密算法，采用C编写，也可以在C++下使用-General md5 encryption algorithm, using C to prepare, you can also use C++

TableCrypt is a file encryption utility. The major difference with most file encryptors is that this program uses a generated table in combination with a password to encrypt a file. This way you need 2 variables to decrypt the file. This is how it works: Generate a 10kb table file and enter a password. The password is used to pick bytes from the table file which in their turn are used to encrypt the bytes of the inputfile with XOR encryption.
