Digital certificate private key

Postby peteroldracer » Sun Nov 28, 2021 7:32 pm

Trying to import my digital certificate into Chrome on my new laptop, it will not recognise the private key. Is there any way to recover this - a simple key was used to import when I first did it.
Both mine and my OH's expire in February so not that vital as I can get new ones nearer the time rather than renew them, but I would like to have the new box working asap.

Hi peteroldracer,

Copy a Backup Copy of your Certificate on to the New system and Import..........no backup copy :!: :!:

Then Export Certificate on your Old system , then copy that file over to the New one and Import.

If you need more details please Post..........as I'm assuming your Computer skills are as good as your Biking........ :D

Update: I have managed to renew both certificates inline (old laptop, using Chrome browser).
Next job to get these onto the new laptop!

I've had no trouble getting it onto my new laptop just using the .pfx file but I wonder how easy it is to renew, do you have to present yourself to the town hall as we did before with ID etc

I did it online - easy process once you have found the starting point!
You can only renew online once - next time it must be in person.

Many thanks. It'll be the first time renewal but not until 2023 so no worries yet. lol

Bets are all off - successfully installed Windows11 thinking it best to be as up to date as possible, but the battery started to drain, and is now flat! The m/c will not start up, only showing a battery symbol for a couple of seconds with a red line at the bottom then goes black. It will not run so maybe the power supply is kaput? Amazon have agree to refund me, but I have to find a way to remove my data from the hard drive on a dead computer!
Oh what fun...

Hi peteroldracer,

What state is to old system with the Digital Signature ...... :?: it's not clear from your Post.

If it still runs do the first half of the procedure and Export to USB memory stick (ideal) or create Folder on C drive and save then there.

I take it your new system has a failed charger.

The old Dell is still working… I have both DSs on a stick, and am currently backing up the whole computer to a WD Elements drive, using Acronis True Image - looks like that may be a long job as it is stalled on ‘calculating the data size’!
It seems that there are many reports of Windows11 not recognising charger ports on laptops, so it may not be the power supply itself. The battery emptied at quite a rate, so possibly the W11 turned the charger into a discharger!
Maybe anyone thinking of doing the W10 to W11 change (I hesitate to say “upgrade”) should defer until things are sorted?
Watch this space!

Both are .pfx files. Now have the backup complete, and current DSs stored on stick and still installed on old Dell. Just need to sort out how to delete my data from new system, which shows no sign of coming to life, so not recognising that there is theoretically power connected. If I am right it should start up even with a flat battery once plugged in to the charger?

Hi peteroldracer,

"Both are .pfx files"........... we can both sleep easy tonight........ :D

"If I am right it should start up even with a flat battery once plugged in to the charger?"......... yes . leave system off and plug charger in and leave overnight, charger should feel warm if its working.

Has anyone nearby a charger that you could try......... :?:

Like so many we have chargers coming out of our ears, for phones, iPads, earphones and so on but they are either only a few watts or a totally different output plug. The one that came with the Teclast is 24 watts with a small male plug. I am in touch with a local computer fixer, so may be able to take it to him in hope he will have something suitable. The internet has videos of how to remove the hard drive and fit it into a simple case with USB connection to run it on another computer….what fun…

Hi peteroldrace,

Have been looking at some Telclast systems.........some seem to have SSD not HDD......what is the model number of your system.. :?:

Your computer guy will be able to copy either onto a external HDD then wipe ie. write zero's into all the sectors so no info goes back with system.
