That is a very old version of Putty. Latest news 2017-02-21 PuTTY 0.68 released, containing ECC, a 64-bit build, and security fixes PuTTY 0.68, released today, supports elliptic-curve cryptography for host keys, user authentication keys, and key exchange. Also, for the first time, it comes in a 64-bit Windows version. 0.68 also contains some security fixes: a vulnerability in agent forwarding is fixed, and Windows DLL hijacking should no longer be possible. -- Jerry _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
