org.opensaml.security.trust.impl.ExplicitKeyTrustEngine

All Implemented Interfaces:

TrustedCredentialTrustEngine<Credential>, TrustEngine<Credential>

public class ExplicitKeyTrustEngine
extends Object
implements TrustedCredentialTrustEngine<Credential>

Trust engine that evaluates a credential's key against key(s) expressed within a set of trusted credentials obtained from a trusted credential resolver. The credential being tested is valid if its public key or secret key matches the public key, or secret key respectively, contained within any of the trusted credentials produced by the given credential resolver.
