See <a href="https://issues.shibboleth.net/jira/browse/MDA-216" title="XMLSignatureSigningStage output changes with Java 11 and latest Santuario" class="issue-link" data-issue-key="MDA-216" style="color: #3b73af; text-decoration: none"><del>MDA-216</del></a>, <a href="https://issues.shibboleth.net/jira/browse/XSTJ-69" title="Santuario 2.0.7 changes Base64 output" class="issue-link" data-issue-key="XSTJ-69" style="color: #3b73af; text-decoration: none">XSTJ-69</a> and <a href="https://issues.shibboleth.net/jira/browse/IDP-1313" title="
 in base 64 in IDP 3.4.0 responses" class="issue-link" data-issue-key="IDP-1313" style="color: #3b73af; text-decoration: none"><del>IDP-1313</del></a>. It has basically screwed us too.</p> <p style="margin: 10px 0 0 0">Unless and until Santuario changes (currently seems like they won't), the only option other than the new default of unconditional CRLF is to set the Java system property <tt>org.apache.xml.security.ignoreLineBreaks</tt> to <tt>true</tt>. This will eliminate all line breaks from the output, so e.g. the Signature value will just be one long line. Note that that may cause different problems with different recipients, even though both are apparently actually valid wrt to the relevant specs.</p> <p style="margin: 10px 0 0 0">We attempt to do this automatically in OpenSAML, but it's only a best-effort attempt. If some of the Santuario static initializers get called before we have a change to set the property, then it doesn't work. That is apparently the case with your use case. So you can try setting it literally as an -D arg to your JRE or else programmatically somewhere in you application that's guaranteed to run very early. We managed to do it in our IdP with Spring wiring.</p> <p style="margin: 10px 0 0 0"> </p> </td>
