<div class="comment-block" style="background-color:#edf5ff;border:1px solid #dddddd;color:#000000;padding:12px;"><p>It looks like the code that is being used by <tt>xmlsectool</tt> to read private key files is actually part of <tt>not-yet-commons-ssl</tt>, not part of <tt>vt-crypt</tt>.</p>
<p>The stable 0.3.9 release of <tt>not-yet-commons-ssl</tt> we are using is from 2007. There's a newer 0.3.11 release from 2009, but it's described as "alpha quality", has never made it to Maven Central, and I can't see any evidence that it understands EC either.</p>
<p>I think this means that handling ECDSA from files would require rewriting the parts of <tt>SecurityHelper.java</tt> that handle files entirely.</p>
<p>I'm going to take a look at whether pulling ECDSA credentials from a keystore is possible, but it rather looks like that is a Java 7 keystore feature.</p>
<p>I have generated some EC resources and written the command-line handling parts for this. They were pretty trivial, and I don't think committing them would do any harm, but by the same token I have no way of testing any of it. Opinions welcome.</p></div>
