Method Detail

values

public static ECDHECryptography.SupportedGroup[] 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 (ECDHECryptography.SupportedGroup c : ECDHECryptography.SupportedGroup.values())
    System.out.println(c);

Returns:

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

valueOf

public static ECDHECryptography.SupportedGroup 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

getId

public int getId()

Gets this group's official id as registered with IANA.

Returns:

the id

fromId

public static ECDHECryptography.SupportedGroup fromId(int id)

Gets the group for a given id.

Parameters:

id - the id

Returns:

the group or null if no group with the given id is (currently) registered

getEcParams

public ECParameterSpec getEcParams()

Gets this group's corresponding EC parameters.

Returns:

the parameter object or null if the params for this group are not (yet) registered

isUsable

public boolean isUsable()

Checks whether this group can be used on this platform.

Returns:

true if the group's domain params are known and the JRE's crypto provider supports it

getUsableGroups

public static ECDHECryptography.SupportedGroup[] getUsableGroups()

Gets all SupportedGroups that can be used on this platform.

Returns:

the supported groups

See Also:

isUsable()

getPreferredGroups

public static List<ECDHECryptography.SupportedGroup> getPreferredGroups()

Gets the preferred supported groups.

Returns:

the groups in order of preference
