org.apache.xml.security.signature.XMLSignature.checkSignatureValue()
Extracts the public key from the certificate and verifies if the signature is valid by re-digesting all References, comparing those against the stored DigestValues and then checking to see if the Signatures match on the SignedInfo. @param cert Certificate that contains the public key part of the keypair that was used to sign. @return true if the signature is valid, false otherwise @throws XMLSignatureException

    if (!oSig.checkSignatureValue(oPubKey))
