ProxyCertInfoExtension (canl 2.8.2 API)

java.lang.Object
- org.bouncycastle.asn1.ASN1Object
- - eu.emi.security.authn.x509.helpers.proxy.ProxyCertInfoExtension

All Implemented Interfaces:

org.bouncycastle.asn1.ASN1Encodable, org.bouncycastle.util.Encodable

Direct Known Subclasses:

DraftRFCProxyCertInfoExtension, RFCProxyCertInfoExtension
```
public abstract class ProxyCertInfoExtension
extends org.bouncycastle.asn1.ASN1Object
```
Proxy cert info extension class. Defines the common contract, there are two implementations DraftRFCProxyCertInfoExtension and RFCProxyCertInfoExtension as the ASN syntax is different for both types of proxies.

public static ProxyCertInfoExtension getInstance(java.security.cert.X509Certificate cert)
                                          throws java.io.IOException
```
    Tries to generate ProxyCertInfoExtension object from the provided certificate. Returns null if the certificate has no proxy extension (draft or rfc).
    
    Parameters:
    
    cert - certificate
    
    Returns:
    
    instance intialized from the certificate object
    
    Throws:
    
    java.io.IOException - IO exception
  - getProxyPathLimit
```
public int getProxyPathLimit()
```
    Get the proxy certificate path length limit of this extension, if set.
    
    Returns:
    
    The number of allowed proxy certificates in the chain allowed after this certificate. -1 if not set.
  - getPolicy
```
public ProxyPolicy getPolicy()
```
    Get the policy object of this extension.
    
    Returns:
    
    The ProxyPolicy object.
