Constructor Detail

ProxyCertInfoExtension

public ProxyCertInfoExtension(int pathLen,
                              ProxyPolicy policy)

Generate new proxy certificate info extension with length limit len and policy policy. Use negative value if no limit is desired.

Parameters:

pathLen - the maximum number of proxy certificates to follow this one. If -1 is used then no limit will be set.

policy - the proxy policy extension.

ProxyCertInfoExtension

public ProxyCertInfoExtension()

Generate a proxy that inherits all rights and that has no cert path length limitations.

ProxyCertInfoExtension

public ProxyCertInfoExtension(byte[] bytes)
                       throws IOException

Constructor that generates instance out of byte array.

Parameters:

bytes - The byte array to consider as the ASN.1 encoded proxyCertInfo extension.

Throws:

IOException - thrown in case the parsing of the byte array fails.

ProxyCertInfoExtension

public ProxyCertInfoExtension(ASN1Sequence seq)
                       throws IOException

Read a proxyCertInfoExtension from the ASN1 sequence.

Parameters:

seq - The sequence containing the extension.

Throws:

IOException

Method Detail

getInstance

public static ProxyCertInfoExtension getInstance(X509Certificate cert)
                                          throws IOException

Tries to generate ProxyCertInfoExtension object from the provided certificate. Returns null if the certificate has no proxy extension (draft or rfc).

Parameters:

cert -

Returns:

instance intialized from the certificate object

Throws:

IOException

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.
