Oh no, I wont do that!! Why you reached such conclusion?
:D
Because you were using this tutorial:
https://github.com/OmniLayer/omniwallet/wiki/Exporting-a-private-key-from-Bitcoin-QT-Bitcoin-core-and-Importing-to-Omniwallet.orgBut as long as you only followed the first part, there shouldn't be any problems (actually, there are no problems anyways, bitcoin is about freedom, i just try to give a warning when people are doing something i personally wouldn't do
)
Oh, ok, that makes sense! My wallets are shown in WIF compressed, I was worried bcz all the guides I found online said I should see the WIF with a 5 in front.
That being said, is it possible to continue to send funds to the public keys associated with the pvt keys in WIF compresssed format? I ask that because all the paper wallet generators I say so far they yields a pvt key in WIF uncompressed format, starting with a 5.
So, if I uninstall Core QT from my computer and store these pvt keys in paper (like a plain paper wallet), plus a backup of the wallet in a pen drive, can I recover the funds from any of those sources? Both the backup or the "paper"?
You could send funds to the address, the address is a hash of your public key...
Private Key =(hash)=> Publick Key =(different hash)=> Address
It should be possible to reconstruct your public key in WIF format beginning with a WIF compressed key. If you're uncertain, you can always download the sourcecode of
https://www.bitaddress.org/, disconnect your pc from the internet, open the sourcecode, go to the "wallet details"-tab and enter your WIF compressed key, the website should be able to re-create your WIF key
BTW: you do realise the private key of your wallet has been on a pc that was connected to the internet? The safest paper wallets are paper wallets generated on an offline machine
Also, as soon as you spend outputs once, you have broadcasted your public key, so it's less safe
. That's why it's usually recommended to discard a paper wallet after it's been swept once... Because you're exporting your pk from core, there is a possibility it was already used to sign scripts to spend unspent outputs, hence it's possible the private key for that public key is already out there (doesn't have to be the case, but i'd personally double check if i was going to collect a lot of outputs on that paper wallet)
