Below patch re-enables the "none" encryption (i.e. no encryption at all)
in OpenSSH 1.2. This mode is required in most countries to legally use SSH
on Amateur Radio frequencies. Note that some countries do not even allow
cryptographic methods used for authentication only.
This is a patch against OpenSSH-1.2pre17. To apply get into the openssh1.2
source directory and type: patch -p1 <openssh-1.2.patch
