Method Detail

validate

public Credential validate(Credential credential,
                           RequestData data)
                    throws WSSecurityException

Validate the credential argument. It must contain a non-null X509Certificate chain or a PublicKey. A Crypto implementation is also required to be set. This implementation first attempts to verify trust on the certificate (chain). If this is not successful, then it will attempt to verify trust on the Public Key.

Specified by:

validate in interface Validator

Parameters:

credential - the Credential to be validated

data - the RequestData associated with the request

Returns:

a validated Credential

Throws:

WSSecurityException - on a failed validation

getCrypto

protected Crypto getCrypto(RequestData data)

validateCertificates

protected void validateCertificates(X509Certificate[] certificates)
                             throws WSSecurityException

Validate the certificates by checking the validity of each cert

Throws:

WSSecurityException

verifyTrustInCerts

protected void verifyTrustInCerts(X509Certificate[] certificates,
                                  Crypto crypto,
                                  RequestData data,
                                  boolean enableRevocation)
                           throws WSSecurityException

Evaluate whether the given certificate chain should be trusted.

Parameters:

certificates - the certificate chain that should be validated against the keystore

crypto - A Crypto instance

data - A RequestData instance

enableRevocation - Whether revocation is enabled or not

Throws:

WSSecurityException - if the certificate chain is not trusted

validatePublicKey

protected void validatePublicKey(PublicKey publicKey,
                                 Crypto crypto)
                          throws WSSecurityException

Validate a public key

Throws:

WSSecurityException
