Examples with Signature org.opensaml.xmlsec.signature.Signature used on opensource projects

Example 1 with Signature

use of org.opensaml.xmlsec.signature.Signature in project cas by apereo.

the class SamlObjectSignatureValidator method verifySamlProfileRequestIfNeeded.

/**
     * Verify saml profile request if needed.
     *
     * @param profileRequest the profile request
     * @param resolver       the resolver
     * @param request        the request
     * @param context        the context
     * @throws Exception the exception
     */
public void verifySamlProfileRequestIfNeeded(final RequestAbstractType profileRequest, final MetadataResolver resolver, final HttpServletRequest request, final MessageContext context) throws Exception {
    final RoleDescriptorResolver roleDescriptorResolver = getRoleDescriptorResolver(resolver, context, profileRequest);
    LOGGER.debug("Validating signature for [{}]", profileRequest.getClass().getName());
    final Signature signature = profileRequest.getSignature();
    if (signature != null) {
        validateSignatureOnProfileRequest(profileRequest, signature, roleDescriptorResolver);
    } else {
        validateSignatureOnAuthenticationRequest(profileRequest, request, context, roleDescriptorResolver);
    }
}

Example 2 with Signature

use of org.opensaml.xmlsec.signature.Signature in project ddf by codice.

the class SimpleSign method signSamlObject.

    if (signature == null) {
        throw new SignatureException("Unable to build signature.");
    }
    signature.setCanonicalizationAlgorithm(SignatureConstants.ALGO_ID_C14N_EXCL_OMIT_COMMENTS);
    signature.setSignatureAlgorithm(sigAlgo);
    BasicX509Credential signingCredential = new BasicX509Credential(certificates[0]);

    }
    if (samlObject instanceof Response) {
        List<Assertion> assertions = ((Response) samlObject).getAssertions();
        for (Assertion assertion : assertions) {
            assertion.getSignature().setSigningCredential(signingCredential);
        }
    }
    samlObject.setSignature(signature);
    SAMLObjectContentReference contentRef = (SAMLObjectContentReference) signature.getContentReferences().get(0);
    contentRef.setDigestAlgorithm(SignatureConstants.ALGO_ID_DIGEST_SHA1);
    samlObject.releaseDOM();
