| If it really is public key, and if the keys really are quite short,
| then its probably really *not* secure. Remember than a 129-digit
| (~425 bit) RSA key was broken in 8 months! A 384-bit RSA key is

The 129 digit key was broken in 8 calendar months and not 8 CPU months,
correct? If so then for most purposes a 129 digit key is more than
adequate. If you are faxing a contract to someone then if the deal
isn't signed in 8 months the odds are that information about it will
leak from a different source than your fax. If I had information that I
wanted to be secure for several years than I would consider using many
more digits than 129.
As to Windows for Workgroups 3.11, I don't know anything about the
security features that are included.
Mike.
