Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description

- Method Detail
  - sendGetChallenge
```
byte[] sendGetChallenge()
                 throws net.sf.scuba.smartcards.CardServiceException
```
    Sends a GET CHALLENGE command to the passport.
    
    Returns:
    
    a byte array of length 8 containing the challenge
    
    Throws:
    
    net.sf.scuba.smartcards.CardServiceException - on tranceive error
  - sendMutualAuth
```
byte[] sendMutualAuth(byte[] rndIFD,
                      byte[] rndICC,
                      byte[] kIFD,
                      SecretKey kEnc,
                      SecretKey kMac)
               throws net.sf.scuba.smartcards.CardServiceException
```
    Sends an EXTERNAL AUTHENTICATE command to the passport. This is part of BAC. The resulting byte array has length 32 and contains rndICC (first 8 bytes), rndIFD (next 8 bytes), their key material kICC (last 16 bytes).
    
    Parameters:
    
    rndIFD - our challenge
    
    rndICC - their challenge
    
    kIFD - our key material
    
    kEnc - the static encryption key
    
    kMac - the static mac key
    
    Returns:
    
    a byte array of length 32 containing the response that was sent by the passport, decrypted (using kEnc) and verified (using kMac)
    
    Throws:
    
    net.sf.scuba.smartcards.CardServiceException - on tranceive error
