The Intel® DAL SDK includes the following API packages:
-
Crypto - provides an interface for cryptographic services.
This package includes interfaces to Cipher, Hash, SecureSession, SequentialCipher, SequentialSignature, Signature and StreamCipher.
-
Langutil - provides language related Intel extensions.
This package includes an interface to Enumerator.
-
UI - interface for building custom user dialogs and displaying them in a protected way.
This package includes an interface to Clickable.
-
Util - interface to Intel proprietary services available for trusted application usage.
This package includes an interface to TimerClient.
For information on the Intel® DAL Host Interface Service APIs, see Intel DAL Host Interface Service.
Developer Notes
When developing your code, keep the following points in mind:
- Ensure that array sizes are large enough. Mismatches between the allocated array size and a called array index value or provided length will result in a java.lang.ArrayIndexOutOfBoundsException.
- Ensure that buffers sizes are positive and large enough for the data to be stored. Mismatches between defined and called buffer sizes will result in a java.lang.ArrayIndexOutOfBoundsException.
- Ensure that required parameters are allocated and initialized. Providing a required parameter as null will result in a java.lang.NullPointerException.
- Floating point or double variable type parameters are not supported by Intel DAL due to the embedded nature of the JVM.
- Ensure that RSA key modulus is not set to zero [0]. A zero value modulus results in a division by zero and that can cause unexpected behaviors in the system.
