Easily create database dumps with support for redacting data (And replacing that data with valid random values).

Supported databases

• MySQL
• PostgreSQL

More coming soon...

Installation

To install redactdump, run the following command:

pip install redactdump

Usage

usage: redactdump [-h] -c CONFIG

redactdump

optional arguments:
  -h, --help            show this help message and exit
  -c CONFIG, --config CONFIG
                        Path to dump configuration.
  -u USER, --user USER  Connection username.
  -p PASSWORD, --password PASSWORD
                        Connection password.
  -d DEBUG, --debug DEBUG
                        Enable debug mode.

Configuration

To create a dump you currently must use a configuration file, however in the future you might be able to do it all via CLI.

Supported replacement values.

redactdump uses faker to generate random data.

replacement can therefore be any function from the following providers: https://faker.readthedocs.io/en/stable/providers.html

NOTE: redactdump is currently NOT tested with all providers, some might trigger bugs

Example configuration:

connection:
  type: pgsql
  host: 127.0.0.1
  port: 5432
  database: postgres

redact:
  patterns:
    column:
      - pattern: '^[a-zA-Z]+_name'
        replacement: name
    data:
      - pattern: '192.168.0.1'
        replacement: ipv4
      - pattern: 'John Doe'
        replacement: name

output:
  type: multi_file
  naming: 'dump-[table_name]-[timestamp]' # Default: [table_name]-[timestamp]
  location: './output/'

Configuration Schema

The configuration schema can be found here

Example

Configuration

connection:
  type: pgsql
  host: 127.0.0.1
  port: 5432
  database: postgres

redact:
  patterns:
    column:
      - pattern: '^new_'
        replacement: name
    data:
      - pattern: '6'
        replacement: random_int

output:
  type: multi_file
  naming: 'dump-[table_name]-[timestamp]' # Default: [table_name]-[timestamp]
  location: './output/'

Original data

(column_1, new_column)

6,"""John Doe"""
6,"John Doe"
6,"John Doe"
6,John Doe
1,\John Doe
1,--John Doe
12312, John Doe
99,!John Doe
99,(John Doe)

Output

INSERT INTO table_name VALUES (890, 'Yolanda Mcdonald');
INSERT INTO table_name VALUES (1982, 'Stephen Lewis');
INSERT INTO table_name VALUES (2952, 'Janet Woodward');
INSERT INTO table_name VALUES (9307, 'Joshua Price');
INSERT INTO table_name VALUES (1, 'Tina Morrison');
INSERT INTO table_name VALUES (1, 'Juan Mejia');
INSERT INTO table_name VALUES (12312, 'Michael Thornton');
INSERT INTO table_name VALUES (99, 'Adrian White');
INSERT INTO table_name VALUES (99, 'Robin Jefferson');
