Thanks for your answer, Aleksey. I think I've understood behaviour of xmlsec in this situation. And according to this logic I assume (and actually I checked it) that when there isn't any valid certificate chain result code of signature verification is still succeeded. Why?
Here is example using command-line tool. ca.crt isn't related to the certificate in license-signed-ca1-server1.xml. So, there isn't any valid certificate chain. Why verification status is OK? > #xmlsec1 --verify --trusted-pem cas/ca2/ca/certs/ca.crt > license-signed-ca1-server1.xml > func=xmlSecOpenSSLX509StoreVerify:file=x509vfy.c:line=360:obj=x509-store:subj=X509_verify_cert:error=4:crypto > library function failed:subj=/C=UA/ST=Kyiv region/L=Kyiv/O=test/OU=Ukraine > Department/CN=server1/[email protected];err=20;msg=unable to > get local issuer certificate > func=xmlSecOpenSSLX509StoreVerify:file=x509vfy.c:line=408:obj=x509-store:subj=unknown:error=71:certificate > verification failed:err=20;msg=unable to get local issuer certificate > OK > SignedInfo References (ok/all): 1/1 > Manifests References (ok/all): 0/0 So, I have another question: Is it possibe to detect with xmlsec that there is no one valid certificate chain up to the one of the trusted certificates? I want to reject signed xml file if there isn't any valid vertificate chain.
