Vs2005! However, if you use a key to encrypt text, numbers, and dates at the same time, it may be a bit of trouble! I just wrote a simple one and tested it! Still usable! Haha!

Define a key type: stringkeytype, which has two member types: Keya and keyb, and a public encryption string publicstr.'II. encryption:① Gener
