Enum Constant Detail

NONE

public static final ExtendedMasterSecretMode NONE

Disable the use of the extended master secret.

OPTIONAL

public static final ExtendedMasterSecretMode OPTIONAL

Optionally use the extended master secret. Session without extended master secret may be resumed. Not RFC 7627 compliant.

ENABLED

public static final ExtendedMasterSecretMode ENABLED

Enable the use of the extended master secret. Session without extended master secret can not be resumed. The server will not assign a session ID, if the client doesn't use the extended master secret. That prevents such a client from accidentally resume the session. RFC 7627 compliant.

REQUIRED

public static final ExtendedMasterSecretMode REQUIRED

Requires the use of the extended master secret.

Method Detail

values

public static ExtendedMasterSecretMode[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (ExtendedMasterSecretMode c : ExtendedMasterSecretMode.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ExtendedMasterSecretMode valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

is

public boolean is(ExtendedMasterSecretMode mode)

Checks, if provided mode is contained in this mode.

Parameters:

mode - mode to be compared

Returns:

true, if the Enum.ordinal() of this mode is larger or equal to the one of the provided mode. false, otherwise.
