  - setData
```
T setData(byte[] data,

    Sets the signed data, the associated signature and the KIF/KVC of the key to be used for the signature verification.
    
    Parameters:
    
    data - The signed data.
    
    signature - The associated signature.
    
    kif - The KIF of the key to be used for the signature verification.

  - setKeyDiversifier
```
T setKeyDiversifier(byte[] diversifier)
```
    Sets a specific key diversifier to use before verifying the signature (optional).
    By default, the key diversification is performed with the full serial number of the target card or SAM depending on the transaction context (Card or SAM transaction).
    
    Parameters:
    
    diversifier - The diversifier to be used (from 1 to 8 bytes long).
    
    Returns:
