MakeKeys is a tool to make
|
|
secret and public key pairs for use in writing and verifying
|
|
digital signatures, such as with the
|
|
<a href="../sigwrite/index.html">SigWrite</a>
|
|
and
|
|
<a href="../sigcheck/index.html">SigCheck</a>
|
|
tools.

|
|
|
|
<p> To use MakeKeys, launch the application, and in the editing window
|
|
that appears, paste in some truly random (not psuedo-random)
|
|
hexadecimal data, which can be generated with
|
|
<a href="../makerand/index.html">MakeRand</a>.
|
|
For example: </p>
|
|
|
|
<blockquote>

|

<p>
|
|
Copy all of the indented text above. Then paste it into MakeKeys,
|
|
which requires getting the clipboard into the emulated Macintosh, if
|
|
MakeKeys is run inside Mini vMac. You can get
|
|
text into the emulated Macintosh using the “Host Paste”
|
|
command in the Edit Menu of MakeKeys. It is like the “Paste” command,
|
|
except that it uses the clipboard of the real computer instead
|
|
of the clipboard of the emulated computer. The keyboard shortcut
|
|
is Command-Option-V. (The “Host Paste” command has
|
|
similar effect to using
|
|
<a href="../clipin/index.html">ClipIn</a>
|
|
and then the normal “Paste” command.)
|
|
</p>
|
|
|
|
<p> MakeKeys only uses multiples of 128 bits, which equals
|
|
32 hexadecimal digits, as on the lines above. Any excess digits
|
|
are discarded. The above 8 lines add up to 1024 bits. </p>
|
|
|
|
<p>
|
|
Before continuing, it would be a good idea to set Mini vMac to
|
|
<a href="../../hardware.html#processor">All Out speed</a>.
|
|
Then, on a modern computer, MakeKeys should
|
|
take less than 5 minutes to run (for a 1024 bit key, as
|
|
in this example).
|
|
At 1x speed, or on a real Macintosh Plus, it takes much longer.
|
|
(Up to a day.)
|
|
The code of MakeKeys is intended to be simple
|
|
to understand and maintain, as opposed to fast.
|
|
</p>
|
|
|
|
<p> Now, click on the status bar, at the bottom
|
|
of the window below the editing area.
|
|
(Choosing the ‘Go’ command from the File menu,
|
|
of the emulated Macintosh, will also work.) </p>
|
|
|
|
<p>
|
|
After a long while, if
|
|
all is well, the edit area is replaced with a new secret key:
|
|
</p>
|
|
|
|

The above secret key is only an example. Normally, a secret key
|
|
should never be given to anyone else. The random hexadecimal data
|
|
used to create the secret key should of course also be kept
|
|
secret.
|
|
</p>
|
|
|
|
<p>
|
|
Again, click on the status bar. The edit area is
|
|
then replaced with the corresponding public key:

When MakeKeys is run inside Mini vMac, you can get
|
|
text out of the emulated Macintosh using the “Host Copy”
|
|
command in the Edit Menu. It is like the “Copy” command,
|
|
except that it uses the clipboard of the real computer instead
|
|
of the clipboard of the emulated computer. The keyboard shortcut
|
|
is Command-Option-C. (The “Host Copy” command has
|
|
similar effect to using the normal “Copy” command and then
|
|
<a href="../clipout/index.html">ClipOut</a>.)
|
|
</p>
|
|
|
|
<p>
|
|
MakeKeys is in part descended from MacPGP source code, which, as far as
|
|
I can tell, allows derived works for noncommercial use.
|
|
</p>
|
|
|
|
<p>
|
|
<!-- MakeKeys generates keys compatibile with MacPGP, but it
|
|
does not encrypt the secret key. -->
|
|
MacPGP has various code to try
|
|
to protect secrets from other software running on the computer.
|
|
MakeKeys does not, instead you should try to secure the entire virtual
|
|
machine that it is run in. Such as by putting the Mini vMac disk
|
|
image on an encrypted volume of the host computer, for a start.
|
|
</p>
|
|
|
|
<!--
|
|
<p>
|
|
Another difference with MacPGP is that MakeKeys sets the user name
|
|
field to "anon", rather than asking for one.
|
|
</p>

|
|

<a href="../mkkeystl/index.html">MkKeysTl</a>

is a command line version of MakeKeys.
|
|
</p>
|
|
|
|
<p>
|
|
MakeKeys is a successor to
|
|
<a href="../pmakkeys/index.html">PMakKeys</a>,
|
|
which uses a different format that is more or less compatible
|

with MacPGP.
