How to use

const ob = require('blur-sensitive-data');

const obf = new ob.Obfuscator().blur("Credit Card Number 4024-0071-4571-8614");

//output: Credit Card Number NOT_VISIBLE_SECURITY_REASON

Objects

The library supports objects whether they are simple or deep, keyword scanning is done on the entire object, there is also a layer to remove circular dependency if it is present.

import Obfuscator from 'blur-sensitive-data';

const dirtyObjectData = {
    Api_key: 'test string api_key',
    test: 'test string teste',
    some: {
        password: 'test string password',
        test: {
            password: 'test string nested password',
            obfuscator: 'test string obfuscator'
        }
    }
}
const configObject = {
    additionalObjectKeys: ['obfuscator']
}

const obf = new Obfuscator(configObject);
const clearData = obf.blur(dirtyObjectData);

//Output:
//{
//    password: 'NOT_VISIBLE_SECURITY_REASON',
//    Api_key: 'NOT_VISIBLE_SECURITY_REASON',
//    test: 'test string teste',
//    some: {
//      password: 'NOT_VISIBLE_SECURITY_REASON',
//      test: {
//        password: 'NOT_VISIBLE_SECURITY_REASON',
//        obfuscator: 'NOT_VISIBLE_SECURITY_REASON'
//    }
//}
//}

Possible parameters for customizing objects obfuscator

String

The library supports type string, in this case the obfuscation is done by matching the searched pattern, whether it is presented only in the sentence or multiple times, and can be in several differents formats and/or intertwined with other texts.

import Obfuscator from 'blur-sensitive-data';

const dirtyStringData = 'this is a string with Credit Card Number 4024-0071-4571-8614, CPF 222.222.222-22 with obfuscator';
const configObject = {
    replacerText: 'NOT_VISIBLE',
    stringPatterns: [Obfuscator.EStringLookUpFields.CPF, Obfuscator.EStringLookUpFields.CREDIT_CARD],
    additionalStringPatterns: [/obfuscator/]
}

const obf = new Obfuscator(configObject);
const clearData = obf.blur(dirtyStringData);

//output: this is a string with Credit Card Number NOT_VISIBLE, CPF NOT_VISIBLE with NOT_VISIBLE
