Private key to bitcoina ddress on Windows 95

[Johanakerblom]

I want to be able to calculate a bitcoin address from a hex-private key of my choosing on windows 95.

I have tried bitaddress.org but it just doesn't work, it takes over a minute to load and all i get is a public key and a small qr-code.

I've also tried https://blockchain.info/sv/q/addrpubkey but i can't even load that page.

Help me!

I can make a small script for you if you can't find anything.

I hope your Windows 95 machine is offline by the way - is it?

[Johanakerblom]

please do

It will be offline and will continue to be offline when i can generate the addresses.

Sorry, I spoke a little too fast. I need to mention that I will only have time to do this by next weekend, not earlier - unless you really need this urgently and are willing to make a donation.

Also, to be sure that your system is able to run Python 2.7 scripts involving EC math, a good and quick test would be to see if my NoBrainr tool is working for you. If it gives any errors, please post them here.

I will run NoBrainr and see what happends.

I will make a donation when the program works.

OK, sounds good - I will wait for your feedback on running NoBrainr before starting.
If you get no errors, I should be able to make the script you need quite fast, as it will easily build on the Python libraries included in the NoBrainr package.

I get this error message when i press nb_1052.exe

When i run NoBrainr/1.052/c_/Python27/python.exe it tells me it needs a later version of Windows

OP, may I ask why Windows 95? Isn't that like two decades old?

[Johanakerblom]

I had the computer lying around, i though i would generate addresses offline with it and then keep it offline in case there is a virus that can upload the addresses that the computer generated offline once it gets online again.

  use LiveCD (linux) on Win95 machine ... that's the right thing to do.

OK, thanks for your feedback. To resolve this, I would suggest that you install Python 2.5.4, which is the latest version of Python that supports win 95 and is available at http://www.python.org/ftp/python/2.5.4/python-2.5.4.msi

If this installation completes without errors, copy the entire 'App' folder from the NoBrainr installation under the Python2.5.4 location and try to run NoBrainr script from the command line - something along the lines of:
 ..\python.exe NoBrainr.py

Also a good idea, of course

Great idea! hah hm..

I'm working on it

Well the problem is that with a Windows version that old you don't even know whether you are getting cryptographically secure private keys. MS software that old did have a weak random number generator if I remember correctly.

You know you can install Linux on old computers. A debian wheezy + xfce installation uses barely any resources. Not sure how feasible that might be for you though. Depends on your skill level.

I want to generate the private keys myself

[Meuh6879]

do a net install ... of linux if you don't have CD reader.

It seems OP doesn't want the Win95 machine to generate the privkeys - just to convert a hex input into a bitcoin address - if I understand the top post correctly.

When i double-click python-2[1].5.4.msi it asks for a program to open it with, hm..

Interesting i will try that is flatflys method doesn't work

That is correct.

You need to install MSI support for Win95:
EDIT: Link offline..

I will make and upload a zip of the proper Python runtime...
