Basic details to make samples work on Linux OS:

• 1) Download samples from GitHub by given above link. It can be done using command "git clone https://github.com/Math-Lock/fully-homomorphic-encryption-practical-and-fast.git" or "git clone git@github.com:Math-Lock/fully-homomorphic-encryption-practical-and-fast.git"
• 2) Make sure that you have python 3.6, 3.7 or 3.8 (recommended) or above - installed
• 3) Make sure that you refer to correct python interpreter path, and correct python alias. It shall be python3.6, python3.7 etc
• 4) Make sure to install correct pip and upgrade it a) sudo apt install python3-pip and b) sudo python3.x -m pip install --upgrade pip
• 5) Go into the repository folder after download and execute "sudo python3.x -m pip install -r samples_requirements.txt" to install all package dependencies. Or in case you use your venv - define it respectfully for it
• 6) sample_mathlock_rest.py works out of the box - just launch it as is
• 7) sample_postgres.py also works out of the box, but required to define table name, by default it's empty string. So open file sample_postgres.py and define it for variable tab_name in method run() It shall be in snake_case, for instance: 'my_unique_test_table'.
  It wasn't defined because we want to make sure every user define own name to not disturb to each other

Basic details to make samples work on Windows OS:

• 1) Download samples from GitHub by given above link. It can be done using command "git clone https://github.com/Math-Lock/fully-homomorphic-encryption-practical-and-fast.git" or "git clone git@github.com:Math-Lock/fully-homomorphic-encryption-practical-and-fast.git"
• 2) Make sure that you have python 3.6, 3.7 or 3.8 (recommended) or above - installed
• 3) Go into the repository folder after download and execute "py -3.x -m pip install -r samples_requirements.txt" to install all package dependencies. Or in case you use your venv - define it respectfully for it
• 4) sample_mathlock_rest.py works out of the box - just launch it as is
• 5) sample_postgres.py also works out of the box, but required to define table name, by default it's empty string. So open file sample_postgres.py and define it for variable tab_name in method run() It shall be in snake_case, for instance: 'my_unique_test_table'.
  It wasn't defined because we want to make sure every user define own name to not disturb to each other

Depends on your programming skills and capabilities - feel free to play with samples and its implementation. Both samples are written in a very minimalistic and simple way to work out of the box.

Short explanation about PostgreSQL MathLock extension:

We have implemented custom extension where introduced new data type - 'mathlock'. Whenever we send data to our demo db, it will be saved there in this specific format. Demo db is capable to do the following things: store encrypted data in our format, query data, perform +,-,/,* homomorphic arithmetic operations with user data.
