Pre-calculated phone numbers hash map

This tool allows to pre-compute a list of hashes for a range of telephone numbers. It can use either postgresql + web service or sqlite3.

Installation

Tested on: Ubuntu 18.04

Install dependencies

sudo apt update
sudo apt install apache2 apache2-utils php php-pgsql libapache2-mod-php libpq5 postgresql postgresql-client postgresql-client-common postgresql-contrib python python-pip python-pip postgresql-server-dev-all
sudo pip install psycopg2

Prepare database

  • Postgresql
sudo -u postgres psql < db_init.sql

Place lookup script into webserver directory:

cp map_hash_num.php /var/www/html/
  • SQLite
python3 hashmap_gen_sqlite.py dbinit

Fill database with hashes for phone numbers range with your favorite preffix (e.g. +12130000000 -> +12139999999)

  • Postgresql
python3 hashmap_gen.py 1213
  • SQLite
python3 hashmap_gen_sqlite.py 1213XXXXXX

Usage

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

ph_candidates

will store the hashes for those numbers in a file named phones.db
