55659a959f ssh_get_password has become ssh_get_line, so it can handle usernames 
as well. This should fix the multiple-reads-on-stdin bug in plink.

313b332a38 Finally fixed the point/pixel confusion in font handling. Thanks to 
Roman Surma for pointing me at the relevant bits of documentation. All
font sizes should now be measured in points, and everything should be
consistent, and (with any luck) old Registry settings should adapt
gracefully too.

d823077f18 Add support for using Diffie-Hellman with short exponents (sshdh.c 
contains a reference to a paper on the subject). Reduces time taken
for DH group exchange to the point where it's viable to enable it
all the time, so I have. :-)

aaeecbb4ea Make the SSH2 traffic analysis defence robust in the face of Zlib 
compression. This involves introducing an option to disable Zlib
compression (that is, continue to work within the Zlib format but
output an uncompressed block) for the duration of a single packet.

16f4ffe616 Implement OpenSSH's private agent forwarding extension. I believe we 
now interoperate with OpenSSH/SSH2 to _exactly_ the same level as we
interoperate with SSH1. Which is pretty cool really.

deccfaa3ef The authentication diagnostics in SSH2 should now be better. 
Additionally, the ability to switch usernames if you mistype the
first one has been restored (although it didn't actually work
because OpenSSH didn't feel like playing; patch submitted :-).

28b1fc766c Preliminary support for RSA user authentication in SSH2! Most of the 
error messages are currently wrong, and Pageant doesn't yet support
the new key type, and I haven't thoroughly tested that falling back
to password authentication and trying invalid keys etc all work. But
what I have here has successfully performed a public key
authentication, so it's working to at least some extent.

b182356f99 Support for selecting AES from the GUI. In the process, I've had to 
introduce another layer of abstraction in SSH2 ciphers, such that a
single `logical cipher' (as desired by a user) can equate to more
than one `physical cipher'. This is because AES comes in several key
lengths (PuTTY will pick the highest supported by the remote end)
and several different SSH2-protocol-level names (aes*-cbc,
rijndael*-cbc, and an unofficial one rijndael-cbc@lysator.liu.se).

cc9d7ba87e Diffie-Hellman group exchange in SSH2. Currently #ifdeffed out 
(change the sense of #ifdef DO_DIFFIE_HELLMAN_GEX in ssh.c) because
it's _far_ too slow. Will be re-enabled once the bignum routines
work a bit faster (or rather a _lot_ faster).

862d6a496d Add a key length indication to each SSH2 cipher structure, in 
preparation for needing to know how much key material each cipher
needs in order to select a suitable Diffie-Hellman group.

f72b5aa95f Remove the last lingering knowledge, outside sshbn.c, of the

0d3ab7306e Timestamp every line of the Event Log. The primary reason for this 
(generating detail in bug reports when SSH2 repeat key exchange
failed) is no longer an issue, but it might be useful for other
things. It's a _log_ dammit, and logs should be timestamped.

b10bc57b03 Moderately evil workaround to compensate for a variation in 
behaviour of FXP_REALPATH. (Specifically, BSD and GNU realpath(3)
disagree over whether to return success when computing the realpath
for a putative new file to be created in a valid directory. There's
no way we can tell from (say) the OpenSSH version string because
OpenSSH might have been compiled to use the local realpath _or_ its
own nonbroken one.)
