The signature is an encrypted hash of your request, all its explained here:

URL Authentication
http://code.google.com/apis/maps/documentation/webservices/#URLSigning

There is an example for illustration:

URL:
http://maps.google.com/maps/api/geocode/json?address=New+York&sensor=false&client=clientID
Private Key: vNIXE0xscrmjlyV-12Nj_BvUPaw=
URL Portion to Sign:
/maps/api/geocode/json?address=New+York&sensor=false&client=clientID
Signature: KrU1TzVQM7Ur0i8i7K3huiw3MsA=
Full Signed URL:
http://maps.google.com/maps/api/geocode/json?address=New+York&sensor=false&client=clientID&signature=KrU1TzVQM7Ur0i8i7K3huiw3MsA=

If you follow the instructions in the link above, you see that the signature
for /maps/api/geocode/json?address=New+York&sensor=false&client=clientID
using crypto key vNIXE0xscrmjlyV-12Nj_BvUPaw= will
be KrU1TzVQM7Ur0i8i7K3huiw3MsA= but if you change the request, then you need
to generate a new signature.

Your crypto key is always the same and you must keep it secret.

For each request, you need to generate a different signature.

Please see the above link for details on what this all means and how to make
it work.

Cheers,
Miguel
