public class PKIXSignatureTrustEngine extends BaseSignatureTrustEngine<net.shibboleth.utilities.java.support.collection.Pair<Set<String>,Iterable<PKIXValidationInformation>>> implements PKIXTrustEngine<Signature>
SignatureTrustEngine
which evaluates the validity
and trustworthiness of XML and raw signatures.
Processing is performed as described in BaseSignatureTrustEngine
. If based on this processing, it is
determined that the Signature's KeyInfo is not present or does not contain a valid (and trusted) signing key, then
trust engine validation fails. Since the PKIX engine is based on the assumption that trusted signing keys are not
known in advance, the signing key must be present in, or derivable from, the information in the Signature's KeyInfo
element.

A candidate verification credential may optionally be supplied. If one is supplied and is determined to successfully verify the signature, an attempt will be made to establish trust on this basis.
If a candidate credential is not supplied, or it does not successfully verify the signature, some implementations may be able to resolve candidate verification credential(s) in an implementation-specific manner based on the trusted criteria supplied, and then attempt to verify the signature and establish trust on this basis.
