Question

I need to generate unique record id for the given unique string.

I tried using uuid format which seems to be good.

But we feel that is lengthly.

so we need to cutdown the uuid string 9f218a38-12cd-5942-b877-80adc0589315 to smaller. By removing ‘-‘ we can save 4 chars. What is the safest part to remove from uuid? We don’t need universally unique id but we like to use uuid as a source but cut down strings.

We need unique id specific to site/database (SQL Server/ADO.NET Data services).

Any idea or sample from any language is fine

Thanks in advance

Answer 1

Why not instead just convert it to a base 64 string? You can cut it down to 22 characters that way.
