After Pavel Kryukov pointed out that I have to put _something_ in the 'ssh_key' structure, I thought of an actually useful thing to put there: why not make it store a pointer to the ssh_keyalg structure? Then ssh_key becomes a classoid - or perhaps 'traitoid' is a closer analogy - in the same style as Socket and Plug. And just like Socket and Plug, I've also arranged a system of wrapper macros that avoid the need to mention the 'object' whose method you're invoking twice at each call site. The new vtable pointer directly replaces an existing field of struct ec_key (which was usable by several different ssh_keyalgs, so it already had to store a pointer to the currently active one), and also replaces the 'alg' field of the ssh2_userkey structure that wraps up a cryptographic key with its comment field. I've also taken the opportunity to clean things up a bit in general: most of the methods now have new and clearer names (e.g. you'd never know that 'newkey' made a public-only key while 'createkey' made a public+private key pair unless you went and looked it up, but now they're called 'new_pub' and 'new_priv' you might be in with a chance), and I've completely removed the openssh_private_npieces field after realising that it was duplicating information that is actually _more_ conveniently obtained by calling the new_priv_openssh method (formerly openssh_createkey) and throwing away the result.
PuTTY README
============
This is the README file for the PuTTY installer distribution. If
you're reading this, you've probably just run our installer and
installed PuTTY on your system.
What should I do next?
----------------------
If you want to use PuTTY to connect to other computers, or use PSFTP
to transfer files, you should just be able to run them from the
Start menu.
If you want to use the command-line-only file transfer utility PSCP,
you will probably want to put the PuTTY installation directory on
your PATH. On Windows 7 and similar versions, you can do this at
Control Panel > System and Security > System > Advanced system
settings > Environment Variables.
Some versions of Windows will refuse to run HTML Help files (.CHM)
if they are installed on a network drive. If you have installed
PuTTY on a network drive, you might want to check that the help file
works properly. If not, see http://support.microsoft.com/kb/896054
for information on how to solve this problem.
What do I do if it doesn't work?
