Code Issues Proposed changes

Change cache uniqifier from using md5 to sha-1

Browse Source 
FIPS 140-2 does not allow MD5 use for most purposes and systems
in "FIPS mode" (fips=1 kernel flag) will cause software using
MD5 from popular libraries to fail.

Also change the default cache dir to use ~/.cache/
