Class KeyLoader

java.lang.Object

  +--KeyLoader

public class KeyLoader

extends java.lang.Object

KeyLoader is an IO interface used by RSA to load and save the keys and modulus associated with one user. Thus KeyLoader is user dependent, and its constructor asks for a username.

In fact, a user's public key is stored in the local directory in a file named "username.pub.key". As well for "username.pri.key" (user's private key) and "username.mod" (its modulus). The methods below do what their names tell.
