<div class="comment-block" style="background-color:#edf5ff;border:1px solid #dddddd;color:#000000;padding:12px;"><p>Both this and <a href="https://issues.shibboleth.net/jira/browse/JOST-217" title="Failed to pass veracode due Use of a Broken or Risky Cryptographic Algorithm (CWE ID 327)">JOST-217</a> are about the use of SHA-1 in generating the SourceID of SAML artifact structures. </p>
<p>In both SAML specs, SHA-1 is RFC "RECOMMENDED" as the way to compute the SourceID, presumably because it's the most convenient and well-known hashing function for reducing an arbitrary length string to the fixed 20-byte sequence mandated by the specific artifact formats in question.</p>
<p>It is debatable whether there's any cryptographic sensitivity here, as the hash function is just being used to compact a string to a known fixed length to be carried in a fixed size data structure.</p>
<p>If there were, I believe that the proper way that the SAML community would address this would be to define new artifact format(s) that would use different (and presumably larger) sizes for the SourceID field, appropriate for newer hashing algorithms like the SHA-2 family. </p>
<p>In any case, in deployments where SAML metadata is being used to drive an artifact exchange, both the artifact producer and artifact consumer pretty much have to agree a-priori on the algorithm in use, so we can't really arbitrarily change this.</p>
<p>So unless Scott tells me I'm wrong, I'm going to mark this as "Won't Fix".</p></div>
