Depends on what you're using to generate the checksum. With only 10
digits it sounds like a high probability of collision. Also, how different
would the checksums for 'aaaaaaaa' and 'aaaaaaab' be?
I used to use MD5 hash algorithms, but those are considered broken by
security experts, so I switched to the SHA-2 hashes.
