Constructor Detail

PKIXBuilderParameters

public PKIXBuilderParameters(KeyStore keystore, CertSelector targetConstraints)

Create a new PKIXBuilderParameters object, populating the trusted certificates set with all X.509 certificates found in the given key store. All certificates found in the key store are assumed to be trusted by this constructor.

Parameters: keystore The key store. targetConstraints The target certificate constraints.

Throws: KeyStoreException If the certificates cannot be retrieved from the key store. InvalidAlgorithmParameterException If there are no certificates in the key store. NullPointerException If keystore is null.

PKIXBuilderParameters

public PKIXBuilderParameters(Set<TrustAnchor> trustAnchors, CertSelector targetConstraints)

Create a new PKIXBuilderParameters object, populating the trusted certificates set with the elements of the given set, each of which must be a {@link TrustAnchor}.

Parameters: trustAnchors The set of trust anchors. targetConstraints The target certificate constraints.

Throws: InvalidAlgorithmParameterException If there are no certificates in the set. NullPointerException If trustAnchors is null. ClassCastException If every element in trustAnchors is not a {@link TrustAnchor}.

Method Detail

getMaxPathLength

public int getMaxPathLength()

Returns the maximum length of certificate paths to build.

If this value is 0 it is taken to mean that the certificate path should contain only one certificate. A value of -1 means that the certificate path length is unconstrained. The default value is 5.

Returns: The maximum path length.

setMaxPathLength

public void setMaxPathLength(int maxPathLength)

Sets the maximum length of certificate paths to build.

Parameters: maxPathLength The new path length.

Throws: IllegalArgumentException If maxPathLength is less than -1.
