Task
Determine if the token object and the
CryptoSystem
support the type of
encryption scheme.
Enable decryption of unprocessed data.
Steps
>
Perform one of the following steps:
•
To create a cryptographic smart card driver that is compatible with BlackBerry Device
Software Version 4.2 or later, create a method that returns a Boolean value that indicates if
the token object supports the specified encryption scheme.
public boolean isSupportedDecryptRSA(RSACryptoSystem cryptoSystem,
CryptoTokenPrivateKeyData privateKeyData)throws
CryptoTokenException
{
return privateKeyData instanceof MyCryptoTokenData;
}
•
To create a cryptographic smart card driver that is compatible with BlackBerry Device
Software Version 4.1 and Version 4.2 or later, and to include the cryptographic smart card
driver in two-factor authentication, create a method that returns a Boolean value that
indicates if the token object supports the specified encryption scheme.
public boolean isSupportedDecryptRSASmartCardImpl( CryptoSystem
cryptoSystem,CryptoTokenPrivateKeyData privateKeyData);

Perform one of the following steps:
•
To create a cryptographic smart card driver that is compatible with BlackBerry Device
Software Version 4.2 or later, create a method that performs decryption of unprocessed data,
for example:
public void decryptRSA(RSACryptoSystem cryptoSystem,
CryptoTokenPrivateKeyData privateKeyData,byte[] input, int
inputOffset,
byte[] output, int outputOffset)throws CryptoTokenException
{
try {//signDecryptHelper is a private helper method.
signDecryptHelper(cryptoSystem, privateKeyData, input, inputOffset,
output, outputOffset, DECRYPT_DESC,
SmartCardSession.DECRYPT_OPERATION);
}
catch (CryptoUnsupportedOperationException e) {
throw new CryptoTokenException(e.toString());
}
}
