  demo.cms.ecc.keystore.SetupCMSEccKeyStore

All Implemented Interfaces:

CMSEccKeyStoreConstants

public class SetupCMSEccKeyStore
extends java.lang.Object
implements CMSEccKeyStoreConstants

Creates a test KeyStore ("cmsecc.keystore") in the current working directory. These keys are used by the ECC demos included in IAIK-CMS. The aliases and the password for accessing the keys and certificates can be found in CMSEccKeyStoreConstants.
