> By default, the Karaf SSH server generates a new 1024-bit DSA host key.
> As we've learned from the crypto specialists in the past few years, this is no longer seen as being a reasonably secure key pair generation algorithm.
> At the time of this writing, a reasonably secure key pair would be generated using RSA with a size of 4096 bits.
