Hi I am attempting to sign https://pastebin.com/36Nvqdpp with a dsa key: xmlsec1 --sign --privkey-pem t/dsa.private.key --id-attr:ID "Response" --id-attr:ID "Assertion" t/xml-sig-unsigned-dsa-multiple.xml It does not show any error messages however it does not sign the output. Any ideas what I am doing wrong? Tim
