I have a unique composite key which is a mixture of a simple stringifed JSON structure concatenated with a Date. It is a fairly complicated looking ID.

"{ foo: bar}Sun Apr 22 2012 12:58:01 GMT+0100 (BST)"

I need a process which translates this string to something with a fewer range of characters. Preferably just alpha-numeric. The process does not have to be reversible.

    Just run this through some hash function or use Base64 encoding for the whole id-string.

     key = window.btoa( id );
