- All Known Implementing Classes:
Method SummaryModifier and TypeMethodDescriptionGet the KeyInfoCredentialResolver instance used to resolve (advisory) signing credential information from KeyInfo elements contained within a Signature element.
(byte signature, byte content, String algorithmURI, CriteriaSet trustBasisCriteria, Credential candidateCredential)Determines whether a raw signature over specified content is valid and signed by a trusted credential.
getKeyInfoResolver@Nullable KeyInfoCredentialResolver getKeyInfoResolver()Get the KeyInfoCredentialResolver instance used to resolve (advisory) signing credential information from KeyInfo elements contained within a Signature element. Note that credential(s) obtained via this resolver are not themselves trusted. They must be evaluated against the trusted credential information obtained from the trusted credential resolver.
- a KeyInfoCredentialResolver instance
(@Nonnull byte signature, @Nonnull byte content, @Nonnull String algorithmURI, @Nullable CriteriaSet trustBasisCriteria, @Nullable Credential candidateCredential) throws SecurityExceptionDetermines whether a raw signature over specified content is valid and signed by a trusted credential.
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.
signature- the signature value
content- the content that was signed
algorithmURI- the signature algorithm URI which was used to sign the content
trustBasisCriteria- criteria used to describe and/or resolve the information which serves as the basis for trust evaluation
candidateCredential- the untrusted candidate credential containing the validation key for the signature (optional)
- true if the signature was valid for the provided content and was signed by a key contained within a credential established as trusted based on the supplied criteria, otherwise false
SecurityException- thrown if there is a problem attempting to verify the signature such as the signature algorithm not being supported
