I'd like to thank everyone for their help. Things are a bit confusing. Here is where I stand. Thanks to Satish Balay, I now have puTTY version 0.53b able to do public key authentication with OpenSSH version 3.5p1-6. He suggested that I modify the public key in the authorized_keys file to edit out all linefeeds, making sure the key is one line. (puTTY appears to save the key with embedded linefeeds.) He also had me edit the first 8 characters to 'ssh-rsa '. The specific public key used was the one generated by puTTYgen, but not the specially generated OpenSSH version of that key which appears in the puTTYgen window. Now, I can connect using public key authentication to accounts that are on boxes running OpenSSH-server 3.5p1-6. (Red Hat 9.) Thanks Satish! Now let's try to connect to a box running OpenSSH-server 3.1p1-6. As soon as you enter the login name in the connection window, the window closes unexpectedly! Turning on logging in puTTY gets a message, "Server refused our key" that appears in the log file. A check of the puTTY web site seems to point to problems with this version of openSSH (see the OpenSSH Bugzilla entry for #138.) There is a patch that can be applied, but checking the spec file for the Red Hat build of OpenSSH-3.1p1-6 seems to show the patch is only applied for Red Hat 6.x boxes. So now I'm toying with the idea of rebuilding it with the OpenSSH patch. That would build it against a new version of openSSL, which may be good, or may break it. I can also try downloading Cygwin, as many of you have pointed out to me, but this is a fairly big download and I'm not sure if the other party would appreciate it. I'll see if OpenSSH for Windows can give me the connectivity needed.
