Field Detail

keyType

public int keyType

Key type. It can be one of the following types defined in PINPadDevice: KEY_TYPE_TDUKPT, KEY_TYPE_MK_SK, KEY_TYPE_FIX, KEY_TYPE_TDUKPT_2009.

masterKeyID

public int masterKeyID

Master key index, ranging from 0 to 49. Index 9 is reserved for EMV kernel offline PIN. This is applicable only when the key type is KEY_TYPE_MK_SK.

keyID

public int keyID

Key index. If the key type is KEY_TYPE_MK_SK, valid constants are USER_KEY_ID_PIN, USER_KEY_ID_MAC, USER_KEY_ID_DATA. For other key types, it represents the key index.

algorithm

public int algorithm

Algorithm type, see ALG_3DES for example.

               int masterKeyID,
               int keyID,
               int algorithm)

Constructs a KeyInfo object for keys of type KEY_TYPE_MK_SK.

Parameters:

keyType - The type of the key, e.g., KEY_TYPE_MK_SK.

masterKeyID - The master key index (0 to 49).

keyID - The specific key index (0, 1, or 2).

algorithm - The cryptographic algorithm, e.g., ALG_3DES.

KeyInfo

public KeyInfo(int keyType,
               int keyID,
               int algorithm)

Constructs a KeyInfo object specifically for DUKPT keys.

Parameters:

keyType - The type of the DUKPT key, either KEY_TYPE_TDUKPT or KEY_TYPE_TDUKPT_2009.

keyID - The key index (0 to 49).

algorithm - The cryptographic algorithm, e.g., ALG_3DES.
