README

Small PHP package to anonymise email addresses for storage or display.

The user side of the email address will always be transformed, but the domain will only be transformed if it is not commonly used for personal email.

Usage

$anonymiser = new EmailAddressAnonymiser\Anonymiser();

// Becomes a***n@gmail.com
$out = $anonymiser->anonymise('admin@gmail.com');

// Becomes n***y@b***o
$out = $anonymiser->anonymise('no-reply@benyoung.io');

CLI

You can use the cli.php script to anonymise email addresses via stdin. For example, given a file named emails.txt:

abc@example.org
admin@gmail.com
john.doe@example.com
no-reply@benyoung.io
root@googlemail.com
webmaster@hotmail.co.uk
webmaster@outlook.com

You can use the following one-liner to process each entry:

cat emails.txt | php cli.php > emails.anon.txt

Which produces emails.anon.txt:

a***c@e***g
a***n@gmail.com
j***e@e***m
n***y@b***o
r***t@googlemail.com
w***r@hotmail.co.uk
w***r@outlook.com
