Method Detail

encrypt

public static String encrypt(DeviceHandler deviceHandler,
             int keyHandle,
             String plaintext)
                      throws YubiHSMInputException,
                             YubiHSMErrorException,
                             YubiHSMCommandFailedException

AES ECB encrypt a plaintext string using a specific key handle.

Parameters:

deviceHandler - the device handler

keyHandle - the key handle to use when encrypting AES ECB

plaintext - the plaintext string

Returns:

a hash string in hex format

Throws:

YubiHSMInputException - if an argument does not validate

YubiHSMErrorException - if validation fail for some values returned by the YubiHSM

YubiHSMCommandFailedException - if the YubiHSM fail to execute the command

decrypt

             int keyHandle,
             String cipherText)
                      throws YubiHSMErrorException,
                             YubiHSMInputException,
                             YubiHSMCommandFailedException

AES ECB decrypt a cipher text using a specific key handle.

Parameters:

deviceHandler - the device handler

keyHandle - the key handle to use when decrypting AES ECB

cipherText - the cipher string

Returns:

a plaintext string

Throws:

YubiHSMInputException - if an argument does not validate

YubiHSMErrorException - if validation fail for some values returned by the YubiHSM

YubiHSMCommandFailedException - if the YubiHSM fail to execute the command

compare
