          public final SSLContext createSSLContext(List<String> negotiableProtocols)
                                            throws Exception

      Specified by:
        `createSSLContext` in interface `SSLUtil`
      Throws:
        `Exception`

    - #### configureSessionContext

          public void configureSessionContext(SSLSessionContext sslSessionContext)

      Specified by:
        `configureSessionContext` in interface `SSLUtil`

    - #### getKeyManagers

          public KeyManager[] getKeyManagers()
                                      throws Exception

      Specified by:
        `getKeyManagers` in interface `SSLUtil`
      Throws:
        `Exception`

    - #### getEnabledProtocols

          public String[] getEnabledProtocols()

      Description copied from interface: `SSLUtil`
      The set of enabled protocols is the intersection of the implemented protocols and the configured protocols. If no protocols are explicitly configured, then all of the implemented protocols will be included in the returned array.
      Specified by:
        `getEnabledProtocols` in interface `SSLUtil`
      Returns:
        The protocols currently enabled and available for clients to select from for the associated connection

    - #### getEnabledCiphers

          public String[] getEnabledCiphers()

      Description copied from interface: `SSLUtil`
      The set of enabled ciphers is the intersection of the implemented ciphers and the configured ciphers. If no ciphers are explicitly configured, then the default ciphers will be included in the returned array.

      The ciphers used during the TLS handshake may be further restricted by the `SSLUtil.getEnabledProtocols()` and the certificates.

      Specified by:
        `getEnabledCiphers` in interface `SSLUtil`
      Returns:
        The ciphers currently enabled and available for clients to select from for the associated connection

    - #### getTrustManagers

          public TrustManager[] getTrustManagers()
                                          throws Exception

      Specified by:
        `getTrustManagers` in interface `SSLUtil`
      Throws:
        `Exception`

    - #### getParameters

          protected CertPathParameters getParameters(String crlf,
                                         KeyStore trustStore,
                                         boolean revocationEnabled)
                                              throws Exception

      Return the initialization parameters for the TrustManager. Currently, only the default `PKIX` is supported.
      Parameters:
        `crlf` - The path to the CRL file.
        `trustStore` - The configured TrustStore.
        `revocationEnabled` - Should the JSSE provider perform revocation checks? Ignored if `crlf` is non-null. Configuration of revocation checks are expected to be via proprietary JSSE provider methods.
      Returns:
        The parameters including the CRLs and TrustStore.
      Throws:
        `Exception` - An error occurred

    - #### getCRLs

          protected Collection<? extends CRL> getCRLs(String crlf)
                                               throws IOException,
                                                      CRLException,

      Load the collection of CRLs.
      Parameters:
        `crlf` - The path to the CRL file.
      Returns:
        the CRLs collection
      Throws:
        `IOException` - Error reading CRL file
        `CRLException` - CRL error
        `CertificateException` - Error processing certificate
