Twig Anonymize

Basic Twig Anonymize extension which allows you to anonymize texts in your twig frontend. It keeps first and last letter (if string longer than 2) and replaces the rest with symbols (asterisks by default). . If you have a variable called mytext then you can anonymize it by typing:

{{ mytext|anonymize }}

Filter has few options:

• keepLength: determines if original lenght of the text should be left intact or should it minify the hidden part.
• replacementChar: character to be used in for the replacement. Defaults to *.

For example:

{{ mytext|anonymize(false, '!') }}

will not keep original length (replace with 3 symbols) and use '!' as the replacement char.

Warning: replacement length is always at least 3 symbols long, no matter the keepLength setting.

Installation

Install using composer:

composer require praetoriantechnology/twig-anonymize:dev-main

NOTE: The dev-main references to the main branch, until there is a stable version that is required.

Since this is not a bundle for Symfony or any other framework but just a simple filter you may need to tell your framework how to look for the filter.

In Symfony, in your services.yaml, add under services:

    praetorian.twig.anonymize_extension:
        class: Praetorian\Twig\Extension\AnonymizeExtension
        tags:
            - { name: twig.extension }
