Getting an Instance of a Key Object

You can get an instance for the following keys:

• AES

• DESede

• HMAC

• RSA

• EC

For example, to get an instance of an AES key:

1. Create a new NaeRijndaelKey object.

2. Pass the session object and the name of the key on the CipherTrust Manager server.

   
   NaeRijndaelKey aeskey = new NaeRijndaelKey(session, keyName);
   

   It creates an instance of the NaeRijndaelKey object that can be used to encrypt and decrypt the data.

   The operation will fail and throw an exception, if:

   • The keyName passed does not match an actual key on the CipherTrust Manager server.

   • Key name matches but the type of the key is different on the CipherTrust Manager server.

   The key object can be used as a Rijndael, which is the superclass of the NaeRijndaelKey class.

Similarly, you can get an instance for DESede, RSA, EC, and HMAC keys.
