Class X509AuthenticationProvider

  • All Implemented Interfaces:
    AuthenticationProvider
    public class X509AuthenticationProvider
extends Object
implements AuthenticationProvider
    An AuthenticationProvider backed by an X509TrustManager and an X509KeyManager to perform remote host certificate authentication. The default algorithm is SunX509 and a JKS KeyStore. To specify the locations of the key store and trust store, set the following system properties:
    zookeeper.ssl.keyStore.location
    zookeeper.ssl.trustStore.location
    To specify store passwords, set the following system properties:
    zookeeper.ssl.keyStore.password
    zookeeper.ssl.trustStore.password
    Alternatively, the passwords can be specified by the following password file path properties:
    zookeeper.ssl.keyStore.passwordPath
    zookeeper.ssl.trustStore.passwordPath
    Alternatively, this can be plugged with any X509TrustManager and X509KeyManager implementation.

        public X509AuthenticationProvider()
                           throws X509Exception
        Initialize the X509AuthenticationProvider with a JKS KeyStore and JKS TrustStore according to the following system properties:

      • X509AuthenticationProvider

        public X509AuthenticationProvider​(X509TrustManager trustManager,
                                  X509KeyManager keyManager)
        Initialize the X509AuthenticationProvider with the provided X509TrustManager and X509KeyManager.
        Parameters:
        trustManager - X509TrustManager implementation to use for remote host authentication.
        keyManager - X509KeyManager implementation to use for certificate management.

    • Method Detail

      • handleAuthentication

        public KeeperException.Code handleAuthentication​(ServerCnxn cnxn,
                                                 byte[] authData)
        Description copied from interface: AuthenticationProvider
        This method is called when a client passes authentication data for this scheme. The authData is directly from the authentication packet. The implementor may attach new ids to the authInfo field of cnxn or may use cnxn to send packets back to the client.
        Specified by:
        handleAuthentication in interface AuthenticationProvider
        Parameters:
        cnxn - the cnxn that received the authentication information.
        authData - the authentication data received.
        Returns:
        TODO

      • getClientId

        protected String getClientId​(X509Certificate clientCert)
        Determine the string to be used as the remote host session Id for authorization purposes. Associate this client identifier with a ServerCnxn that has been authenticated over SSL, and any ACLs that refer to the authenticated client.
        Parameters:
        clientCert - Authenticated X509Certificate associated with the remote host.
        Returns:
        Identifier string to be associated with the client.

      • matches

        public boolean matches​(String id,
                       String aclExpr)
        Description copied from interface: AuthenticationProvider
        This method is called to see if the given id matches the given id expression in the ACL. This allows schemes to use application specific wild cards.
        Specified by:
        matches in interface AuthenticationProvider
        Parameters:
        id - the id to check.
        aclExpr - the expression to match ids against.
        Returns:
        true if the id can be matched by the expression.

      • isAuthenticated

        public boolean isAuthenticated()
        Description copied from interface: AuthenticationProvider
        This method is used to check if the authentication done by this provider should be used to identify the creator of a node. Some ids such as hosts and ip addresses are rather transient and in general don't really identify a client even though sometimes they do.
        Specified by:
        isAuthenticated in interface AuthenticationProvider
        Returns:
        true if this provider identifies creators.
