求大神帮忙~~~~~关于DES加密的问题
论坛的各位大神，帮个忙。
我想通过DES加密来存储我的各种密码~
我想用一个固定的Key来加密字符。
问题来了
public string GenerateKey()
{
DESCryptoServiceProvider desCrypto = (DESCryptoServiceProvider)DESCryptoServiceProvider.Create();
return ASCIIEncoding.ASCII.GetString(desCrypto.Key);
}
每次的Key都是变化的，怎么把我的口令（例如 hack+=3? ）转换为Key？我试过强制转换，但是不知怎么操作。
大神们，求解！！！求具体做法！！
[解决办法]
byte[] key = { 0x12, 0x34, 0x56, 0x78, 0x90, 0xAB, 0xCD, 0xEF }
这种格式
