 &lt;p&gt;p2 detects errors which may have been introduced during artifact transmission/storage by calculating artifact checksum using MD5 hash function. As a &lt;a href=&quot;https://en.wikipedia.org/wiki/Collision_attack&quot;&gt;collision attack&lt;/a&gt; and a &lt;a href=&quot;https://en.wikipedia.org/wiki/Chosen-prefix_collision_attack&quot;&gt;chosen-prefix collision attack&lt;/a&gt; against MD5 have been demonstrated in public, it can be used but only to detect unintentional corruption. Current implementation is not extensible and doesn&apos;t allow to use other, more collision-resistant, hash functions.&lt;/p&gt;
