The content of the <ds:SignatureValue> tag in my request that is generated with xmlsec appears to be broken up across 3 lines, with line breaks after the 76th character, providing there are that many characters. is this not a problem? the receiving server appears to expect one line without breaks. how can i remedy this?
Try this before signing:
org.apache.xml.security.utils.Base64.setBase64WrapLength(0);
