Java examples

This example utility demonstrates application key generation and import.

This example utility generates an RSA Key and optionally exports the public key out of a module as plain text.

It demonstrates the creation of an OCS.

This example utility demonstrates the use of the mergeKeyIDs method in the Key class.

This method merges all the loaded private keyids into a single keyid that can be used in nCore API calls when load-sharing is required.

Displays information about the Security World.

This example Java utility is analogous to its C version except that NFKMInfo.java does not return information on world/module generation.

This is an example program to demonstrate interacting with the NVRAM and RTC. The program allows you to list all files in NVRAM, delete a file in NVRAM, delete all the files in NVRAM, display the current time in the RTC and to set the RTC to the system clock.

This is a simple example that graphically encrypts and decrypts data with a Triple-DES (DES3) key from the Security World. Cipher Block Chaining mode (CBC) and initialization vectors are selected randomly. This information is prefixed to the cipher text.

SimpleCrypt.java only works with module protected Triple-DES (DES3) keys.

This example utility polls all the available slots.

You can determine whether the state of the slot has changed by calling getIC() on the slot. This method is more efficient than using update(). The module serial number, slot number, and insertion count are displayed when a card is inserted or removed.

This example generates an RSA key pair and an X509 public key specification. It performs encryption and decryption of random plain text.

This example utility demonstrates:

This example utility demonstrates:

This example utility demonstrates:

This example utility demonstrates how to generate and store key for use in Ed25519 and Ed25519ph operations.

The example generates an Ed25519 key pair, creates a KeyStore and stores both halves of the key pair.

This example measures the data rate achieved by different symmetric encryption and decryption operations. You can use optional program arguments to change the cipher, key, data, and provider parameters.

This example utility does performance testing for RSA, DSA, ECDSA and Ed25519 private key operations.

It demonstrates:

This example measures the data rate achieved by many threads simultaneously performing signing and verifying operations. You can use optional program arguments to change the thread, key, data, provider, and sampling parameters.

This example measures the time taken to get many keys from an nCipher.sworld key store. It also demonstrates how to create, load and store key stores, as well as how to set and get key entries.

This example creates a new KeyStore containing an AES key. It performs load-balanced encryption and decryption of random plain text using a KeyStore loaded key.

This example loads an existing AES key from the Security World across all usable modules and performs load-balanced encryption and decryption of random plain text.

This example generates RSA, DSA, ECDSA and Ed25519 key pairs. For the associated mechanism of each key type, it performs signing and verification of random plain text.

Before building this example, the user will need to edit SslClientExample.java to insert an appropriate https web site address in the two relevant places. When run, this example connects to the user-specified secure web site over an encrypted SSL connection and dumps the index page to the console.

Before running this example, you must run PrepareSslExamples.java. For more information, see Java JCE/CSP example utilities

This example creates a simple SSL Web server instance on the local host that can be accessed with a Web browser.

Before running this example, you must run PrepareSslExamples.java. For more information, see Java JCE/CSP example utilities

This example generates symmetric keys and uses them to perform encryption and decryption of random plain text with different cipher modes and padding types.

This example utility demonstrates:

This example utility displays information in a blob. It demonstrates how to determine information about the contents of a blob.

BlobInfo.java is analogous to the C Generic Stub call NFast_ExamineBlob.

This example utility is a function-based wrapper to symmetric bulk-encryption channels for use by EasyConnection.java.

This example utility checks modulo-exponentiation operations against a test file.

This example utility is a test program for some module algorithms. It demonstrates:

This example utility is for DES known answer tests.

It demonstrates simple nCore key management usage.

This example utility provides a simple demonstration of the use of DeriveKey.

This example utility is a function-based interface to a subset of nCore.

This example utility displays enquiry information.

It demonstrates:

This example utility does performance testing for modexp code.

It demonstrates:

This example utility generates a certificate.

It demonstrates the use of the BuildCmdCert class.

This example utility initializes a module with a dummy HKNSO (like the C initunit utility).

This example utility is a helper class used by SigTest. It is an example extension to jnfopt for looking up an nCore Enumeration class. It cannot be invoked by itself.

This example utility reports the embedded version information from the current nfjava component. ReportVersion.java outputs the version of the nfjava library found on the class path.

These examples are not intended to be invoked directly. They are called by other programs. The following two utilities, EasyConnection and Channel, form a Java analog of the nCore simple command functions as shipped to C developers in libexamples.a. You can compare and contrast this example with the C example simplecmd.h.

You cannot invoke EasyConnection and Channel directly; CrypTest invokes them. For more information, see the Javadoc documentation.

This example utility is shared code used by SigTest and FloodTest and cannot be invoked on its own. It has helper classes for output reporting by SigTest and FloodTest.

This example utility does signature performance testing.

It demonstrates asynchronous command processing (NFastApp_Wait and NFastApp_Query).
