Task
Retrieve random data from
the internal random number
generator of the smart card.
See "Code sample: Creating a cryptographic session for a cryptographic smart card driver" on page 18 for more
information.
Create a cryptographic token for private key operations
Task
Create a token class.
Determine if the token object can perform
authentication for a BlackBerry device
user.
Determine if the token object supports the
CryptoSystem
current

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 class that extends an RSA®, DSA, or ECC token class.
For example:
final class MyRSACryptoToken extends RSACryptoToken implements
Persistable
•
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 class that extends the
SmartCardRSACryptoToken
final class MyRSACryptoToken extends SmartCardRSACryptoToken
>
Create a method that returns true if your token object prompts the BlackBerry device user for
authentication information.
public boolean providesUserAuthentication()
{
return true;
}
>
Create a method that returns a Boolean value that indicates if the token object supports the
CryptoSystem
current
public boolean isSupported(CryptoSystem cryptoSystem, int operation)
{
return (operation == PRIVATE_KEY_OPERATION);
}
class.
