public enum ECryptoKeyDerivationMethod
extends Enum<ECryptoKeyDerivationMethod>
implements com.helger.base.id.IHasID<String>

Enumeration of key derivation functions used in key agreement schemes. The key derivation function takes the shared secret from key agreement and derives the actual key encryption key.

Since:

4.4.0

Method Details

values

public static ECryptoKeyDerivationMethod[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static ECryptoKeyDerivationMethod valueOf(String name)

Parameters:

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

Returns:

the enum constant with the specified name

Throws:

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

NullPointerException - if the argument is null
