For greater security, check the size and MD5 and SHA-1 hash values (digests) of the downloaded Spa.jar file
against the tabulated values given in the initial Spa page. Do not compute the hashes
with either the Spa applet or the downloaded Spa.jar file. Instead,
compute them with your own trusted utility.
File size is a primary indicator of validity; check that the file sizes match exactly before calculating any hash!
Most operating systems contain software to compute the file hashes.
