  - ### createSSLContext

    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, CertificateException
    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

  - ### getImplementedProtocols

    protected abstract Set<String> getImplementedProtocols()

  - ### getImplementedCiphers

    protected abstract Set<String> getImplementedCiphers()

  - ### getLog

    protected abstract Log getLog()

  - ### isTls13RenegAuthAvailable

    protected abstract boolean isTls13RenegAuthAvailable()

  - ### createSSLContextInternal

    protected abstract SSLContext createSSLContextInternal(List<String> negotiableProtocols) throws Exception
    Throws:
      `Exception`
