Installation

1. Clone the repository:

git clone https://github.com/hipnologo/data_anonymizer_app.git

2. Change to the project directory:

cd data_anonymizer_app

3. Install the required dependencies using pip:

pip install -r requirements.txt

4. Generate a secret key and create a .env file in the project directory by running the genkey.py script:

python genkey.py

This will create a .env file containing the SECRET_KEY variable with a randomly generated 32-byte hexadecimal value. Alternatively you can use:

echo "SECRET_KEY=your_secret_key_here" > .env

5. Generate fake random data into a .csv file which will be placed under data folder for testing purposes.

python gendata.py

Bonus: create a .gitignore for the project.

curl -o .gitignore https://raw.githubusercontent.com/github/gitignore/main/Python.gitignore

Usage

1. Start the Flask development server:

python app.py

2. Open a web browser and navigate to http://127.0.0.1:5000.

3. Upload a CSV or Excel file and choose the desired anonymization actions for each column.

4. Download the anonymized file.
