Creating a key pair

A new key pair can be generated using hospitality_keygen.jar from the hospitality project:

java -jar hospitality_keygen.jar <basename>

This creates two files: <basename>.prv and <basename>.pub containing RSA private and public keys respectively. The files' format is just the getEncoding() method of the java.security.Key interface: PKCS#8 for the private key and X.509 for the public key.

In general Jtrix can handle any encryption standard handled by the underlying VM. Beatrix and the cluster happen to use RSA.
