Comment 2 for bug 316438

The reason its 32 characters is that MD5 is normally 128-bit? Therefore 32 hexadecimal characters. I don't see any problem increasing the size of the column on the display table - and XMDS should definitely enforce the size. Before I make such a change what do we think the appropriate size would be?

What are you passing through MD5 to generate a unique key? The MD5 is only going to be as unique as that you are using to get it. If you made it a MD5 of date, server key and a random number I doubt that another client would ever conflict.
