[xmlsec] Problem when using the xmlSecOpenSSLAppKeyLoadMemory() API.

[Venkataragavan Vijayakumar]

Hi all,

Please check anything i am doing wrong in the key buffer creation. simply I
am directly copying the key from the private key file generated using
openssl. I have attached sample key file(dtls.key) , where i have taken the
key.

Please help me to solve this issue.


 const xmlSecByte *keybuf =
"MIIBOwIBAAJBALe2myLsvZaYVDcZAkaHfaYnwlojm7ebRHGuLGUvYXHgmdMU9LLT6cMABq2me+ioQLhB0+KY4Nth91NG52spEtECAwEAAQJAMKWQCv15bolDs5tRuO9j3D2m/0tyjnn0881VQC39tbN6w+tCVhUHPEy+3l/jf7b/xkuIcbgV2voXVEVFjHmwCQIhAOTF+LdlVZ/TbIEM+GRTaYQQEXz0NjWWIARxDv6OWvdzAiEAzZPK3ZqQtXw3/E2HU6DGBFxB8S92PGk5EFKWaUtG06sCIQC+Cx9j6lBI5u9Z/RZS8V/UDy0X6h8mQMH0Lp9QI525tQIgaslZuNFAWDWlc1bmc+dw1PUDgAByf6D89mCgJyPmL68CIQCmkdwn7cuWI4GlVJnpDZ2iHZjeiih3oVR73/WquuyJqw==";
     xmlSecSize keysize = strlen(keybuf);


  assert(tmpl_file);
  assert(key_file);

  /* load template */
  doc = xmlParseFile(tmpl_file);
  if ((doc == NULL) || (xmlDocGetRootElement(doc) == NULL)){
    fprintf(stderr, "Error: unable to parse file \"%s\"\n", tmpl_file);
    goto done;
  }

  /* find start node */
  node = xmlSecFindNode(xmlDocGetRootElement(doc), xmlSecNodeSignature,
xmlSecDSigNs);
  if(node == NULL) {
    fprintf(stderr, "Error: start node not found in \"%s\"\n", tmpl_file);
    goto done;
  }

  /* create signature context, we don't need keys manager in this example */
  dsigCtx = xmlSecDSigCtxCreate(NULL);
  if(dsigCtx == NULL) {
    fprintf(stderr,"Error: failed to create signature context\n");
    goto done;
  }



  /* load private key, assuming that there is not password */

  dsigCtx->signKey =
xmlSecCryptoAppKeyLoadMemory(keybuf,keysize,xmlSecKeyDataFormatPem, NULL,
NULL, NULL);
  if(dsigCtx->signKey == NULL) {
    fprintf(stderr,"Error: failed to load private pem key from \"%s\"\n",
key_file);
    goto done;
  }

Thanks,
Venkat.
