Class ProxyPathValidator

java.lang.Object

org.globus.gsi.proxy.ProxyPathValidator

public class ProxyPathValidator
extends Object

Performs certificate/proxy path validation. It supports both old style Globus proxy as well as the new proxy certificate format. It checks BasicConstraints, KeyUsage, and ProxyCertInfo (if applicable) extensions. It also checks for presence in CRLs and signing policy compliance. This validator requires that each CA be installed with signing policy. It also provides a callback interface for custom policy checking of restricted proxies.
Currently, does not perform the following checks for the new proxy certificates:

1. Check if proxy serial number is unique (and the version number)
2. Check for empty subject names

ProxyPathValidator

public ProxyPathValidator()

Method Detail

isLimited

public boolean isLimited()

Returns if the validated proxy path is limited. A proxy path is limited when a limited proxy is present anywhere after the first non-impersonation proxy certificate.

Returns:

true if the validated path is limited

getIdentityCertificate

public X509Certificate getIdentityCertificate()

Returns the identity certificate. The first certificates in the path that is not an impersonation proxy, e.g. it could be a restricted proxy or end-entity certificate

Returns:

X509Certificate the identity certificate

getIdentity

public String getIdentity()

Returns the subject name of the identity certificate (in the Globus format)

Returns:

the subject name of the identity certificate in the Globus format

getIdentityCertificate()

removeProxyPolicyHandler

public ProxyPolicyHandler removeProxyPolicyHandler(String id)

Removes a restricted proxy policy handler.

Parameters:

id - the Oid of the policy handler to remove.

Returns:

ProxyPolicyHandler the removed handler, or null if there is no handler registered under that id.

setProxyPolicyHandler

public ProxyPolicyHandler setProxyPolicyHandler(String id,
                                       ProxyPolicyHandler handler)

Sets a restricted proxy policy handler.

Parameters:

id - the Oid of the proxy policy to install the handler for.

handler - the proxy policy handler.

Returns:

ProxyPolicyHandler the previous handler installed under the specified id. Usually, will be null.

getProxyPolicyHandler

public ProxyPolicyHandler getProxyPolicyHandler(String id)

Retrieves a restricted proxy policy handler for a given policy id.

Parameters:

id - the Oid of the proxy policy to get the handler for.

Returns:

ProxyPolicyHandler the policy handler registered for the given id or null if none is registered.

reset

public void reset()

Resets the internal state. Useful for reusing the same instance for validating multiple certificate paths.

setRejectLimitedProxyCheck

public void setRejectLimitedProxyCheck(boolean rejectLimProxy)

If set, the validate rejects certificate chain if limited proxy if found

validate

public void validate(X509Certificate[] certPath,
            X509Certificate[] trustedCerts)
              throws ProxyPathValidatorException

Performs all certificate path validation including checking of the signatures, validity of the certificates, extension checking, etc.
It uses the PureTLS code to do basic cert signature checking checking and then calls validate for further checks.

Parameters:

certPath - the certificate path to validate.

trustedCerts - the trusted (CA) certificates.

Throws:

ProxyPathValidatorException - if certificate path validation fails.

Throws:
