Re^3: Creating a rainbow table for a ten-digit number: Advice?

If all you want is the appearance of security, why not use XOR? Better yet, use something like Crypt::Rijndael so you can claim to be using the Advanced Encryption Standard.

As far as the database goes, you can encrypt your data (with padding, Xilman++) before you do your INSERT and decrypt after you do your SELECT.

With respect, XOR only provides the appearance of security to the naive or ignorant. Ethics committees are, for the most part, neither.	[reply]

Indeed, I was being a bit silly about using XOR, which is why I included the bit about AES.	[reply]
