public class TrustManagerFactory extends Object
Every implementation of the Java platform is required to support the following standard TrustManagerFactory
algorithm:

A new TrustManagerFactory object encapsulating the TrustManagerFactorySpi implementation from the first Provider that supports the specified algorithm is returned.

method.

The provider typically uses a KeyStore as a basis for making trust decisions.
For more flexible initialization, please see init(ManagerFactoryParameters)
.

In some cases, initialization parameters other than a keystore may be needed by a provider. Users of that particular provider are expected to pass an implementation of the appropriate ManagerFactoryParameters
as defined by the provider. The provider can then call the specified methods in the ManagerFactoryParameters
implementation to obtain the needed information.
