MKDMethod (jPOS 2.1.9)

java.lang.Object
- java.lang.Enum<MKDMethod>
- - org.jpos.security.MKDMethod

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<MKDMethod>
```
public enum MKDMethod
extends java.lang.Enum<MKDMethod>
```
Indicate method for the derivation by the issuer of a 16-byte ICC Master Key used for Application Cryptogram generation, issuer authentication, and secure messaging.
These methods take as input the PAN and PAN Sequence Number, plus a 16-byte Issuer Master Key IMK, and produce the 16-byte ICC Master Key MK
Described in EMV v4.2 Book 2, Annex A1.4 Master Key Derivation

```
public static MKDMethod[] 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 (MKDMethod c : MKDMethod.values()) System.out.println(c);
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static MKDMethod valueOf(java.lang.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:
    
    java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
    
    java.lang.NullPointerException - if the argument is null
