Method Details

createSSLContext

static SSLContext createSSLContext(SSLContext sslContext,
 X509KeyManager keyManager,
 X509TrustManager trustManager)

Creates an instance of Tomcat's SSLContext from the provided inputs. Typically used when the user wants to provide a pre-configured javax.net.ssl.SSLContext instance. There is no need to call SSLContext.init(KeyManager[], TrustManager[], java.security.SecureRandom) on the returned value.

Parameters:

sslContext - The JSSE SSL context

keyManager - The JSSE key manager

trustManager - The JSSE trust manager

Returns:

An instance of Tomcat's SSLContext formed from the provided inputs.

createSSLContext

SSLContext createSSLContext(List<String> negotiableProtocols)
                     throws Exception

Creates an SSL context for the given negotiable protocols.

Parameters:

negotiableProtocols - The negotiable protocols

Returns:

the SSL context

Throws:

Exception - if an error occurs

getKeyManagers

KeyManager[] getKeyManagers()
                     throws Exception

Returns the key managers.

Returns:

The key managers

Throws:

Exception - if an error occurs

getTrustManagers

TrustManager[] getTrustManagers()
                         throws Exception

Returns the trust managers.

Returns:

The trust managers

Throws:

Exception - if an error occurs

configureSessionContext

void configureSessionContext(SSLSessionContext sslSessionContext)

Configures the given SSL session context.

Parameters:

sslSessionContext - The SSL session context to configure

getEnabledProtocols

String[] getEnabledProtocols()
                      throws IllegalArgumentException

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.

Returns:

The protocols currently enabled and available for clients to select from for the associated connection

Throws:

IllegalArgumentException - If there is no intersection between the implemented and configured protocols

getEnabledCiphers

String[] getEnabledCiphers()
                    throws IllegalArgumentException

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 getEnabledProtocols() and the certificates.

Returns:

The ciphers currently enabled and available for clients to select from for the associated connection

Throws:

IllegalArgumentException - If there is no intersection between the implemented and configured ciphers
