Prevent repeated hashing

[kuzmandi]

I have original values ​​and already built hashes, both should result in the same identicon. Do I have to hash all hashes again? Or is there a solution for this (without changing setString($string) for myself)?

Best regards

✅ Resolved in v3.0.0 #82

You can now use pre-computed hashes directly with skipHashing():

// GDPR: emails stored as hashes in database
$storedHash = 'acbd18db4cc2f85cedef654fccc4a4d8';

$identicon = (new IdenticonBuilder())
    ->skipHashing()
    ->build();

$avatar = $identicon->getImageDataUri($storedHash);

This ensures md5("john@example.com") and its pre-computed hash produce identical identicons.

See GDPR documentation.
