Encrypt file using public key?

[James Tikalsky]

This seems like it should be simple, but I'm getting confused. I have a binary file which I've discovered contains two keys: A Master and a Sub.

I've been able to read the file as a byte array from the file system, then add it to the keyStore using the method:

  
keyStore.setKeyEntry(keyName, encKey, chain);

I've verified that the key exists using:

  
keyStore.isKeyEntry(keyName);

which returns true. I can also delete the key from the keyStore using:

keyStore.deleteEntry(keyName);

Now, I'd like to use the public key to encrypt a file, but I'm unable to get a reference to the Key using:

Key key = keyStore.getKey(keyName, KEYSTORE_PASSWORD);

Is there something I'm missing?

You can try the following:

KeystoreManager.setCacertsFile(cacertsFile);
PrivateKey privKey= KeystoreManager.getPrivKey();
X509Certificate[] certChain = KeystoreManager.getCertChain();

Set the keystore manager to point to the file that contains your keys, and then retrieve the corresponding public and private keys.
