TranslationHelper::createTextHash() 

\nn\t3::TranslationHelper()->createTextHash($text = ''); 

Generates a unique hash / checksum from the text. The transferred text is always the base language. If the text in the base language changes, the method returns a different checksum. This recognizes when a text needs to be retranslated. Pure changes to whitespaces and tags are ignored.

$translationHelper->createKeyHash( '12345' );
$translationHelper->createKeyHash( ['my', 'key', 'array'] );
