Prepare database
sudo -u postgres psql < db_init.sql
Place lookup script into webserver directory:
cp map_hash_num.php /var/www/html/
Fill database with hashes for phone numbers range with your favorite preffix (e.g. +12130000000 -> +12139999999)
python ./hashmap_gen.py 1213
Now you can get mobile phones by 3 bytes of SHA256(phone_number) this way:
http:/127.0.0.1/map_hash_num.php?hash=112233
