[xmlsec] xmlsec1-1.2.16 to xmlsec1-1.2.29 decrypt problems

[Floodeenjr, Thomas]

Aleksey,

Is there a limitation with xmlsec1-1.2.29 on the size of the encrypted XML that is being decrypted? The file seems to encrypt OK, but will not decrypt. (290 MB). Smaller files work fine both ways. We are using libxml2-2.9.9 and openssl-1.1.1d.  (Previously we used libxml2-2.7.8 and openssl-1.0.2g, and it worked fine.)

Thanks,
-Tom

It returns here with -1

    if(ret != XML_ERR_OK) {
        xmlSecXmlError("xmlParseInNodeContext", NULL);
        return(-1);
    }
