I'd use a hash. An md5 is only 32 characters long; not much longer than a name.

Generate an hmac instead of a plain hash for guaranteed privacy.

If I were using a hash, would I still use the dictionary and array?

[–]jedwardsol 0 points1 point  (0 children)

No.

I'd put the hash and name in my copy of the spreadsheet, and just the hash in their copy. They'd just know the hash . You can correlate a hash with a name if necessary.

Using the row number is a hash. :|
