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> <img src="https://www.gryphel.com/d/minivmac/extras/makekeys/screen.gif" width=514 height=344 border=0 alt="Screenshot"> </p>
<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>
<pre>
42D8A22109876964FEA9CF70F6DDDC54
D0DBA11B7066D7249369E381872CB523

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>
