Re: Verifying signature with embedded x509 cert

No joy. It refuses to load the key. The irony is that I can use the xmlsec utility and pass it the name of the temp file I create with the key and it will load and verify. It just won't do it in my program. Here's the errors I'm seeing:

func=xmlSecOpenSSLAppKeyLoadBIO:file=app.c:line=260:obj=unknown:subj=d2i_PrivateKey_bio and d2i_PUBKEY_bio:error=4:crypto library function failed: 
func=xmlSecOpenSSLAppKeyLoadMemory:file=app.c:line=193:obj=unknown:subj=xmlSecOpenSSLAppKeyLoadBIO:error=1:xmlsec
 library function failed: 
func=xmlSecDSigCtxProcessKeyInfoNode:file=xmldsig.c:line=871:obj=unknown:subj=unknown:error=45:key is not found: 
func=xmlSecDSigCtxProcessSignatureNode:file=xmldsig.c:line=565:obj=unknown:subj=xmlSecDSigCtxProcessKeyInfoNode:error=1:xmlsec
 library function failed: 
func=xmlSecDSigCtxVerify:file=xmldsig.c:line=366:obj=unknown:subj=xmlSecDSigCtxSigantureProcessNode:error=1:xmlsec library function failed: 

The signature will verify with the xmlsec utility if I pass it the cert, just not from my program. My next step is to reduce things to the bare essentials and try again
