我想将日期时间转换为 6 位数字，然后将其转换回准确的日期时间。这个有加密方法吗？

Question

这是我想要做的 (1) 将日期时间转换为 6 位数字；(2) 将 6 位数字转换为输入日期时间。有什么建议吗？

Answer 1

下面是我为完全相同的目的而准备的使用 gtk（在 linux 上）的 python 脚本。如果您有兴趣，我可以将其转换为 C，或者您可以尝试这样做...... 为了尝试它，输入日期 YYMMDDHHmmss 然后点击转换按钮，...非常方便 !!

唯一，我不得不用数字和字母!!!!!

I want to convert date time into 6 digit number, then convert it back into the exact date time. Is there a encryption method to this?

c++
