Yeah, MD5 has been known to be broken if you can append binary data. (Not sure if that&#x27;s been &quot;beaten&quot;, maybe you don&#x27;t need full binary data any longer.)<p>... but <i>accidental</i> collisions? That&#x27;s still hugely more likely to be &quot;you&#x27;re misremembering&quot; or &quot;you misread&quot; than a real collision.
