Constructor Detail

AIM

public AIM(java.lang.String id,
           java.lang.String password)

Constructor for AIM.

roastPassword

protected java.lang.String roastPassword(java.lang.String str)

Called to roast the password. Passwords are roasted when sent to the host. This is done so they aren't sent in "clear text" over the wire, although they are still trivial to decode. Roasting is performed by first xoring each byte in the password with the equivalent modulo byte in the roasting string. The result is then converted to ascii hex, and prepended with "0x". So for example the password "password" roasts to "0x2408105c23001130"

Parameters:

str - The password to roast

Returns:

The password roasted
