You'll have to decrypt the paper wallets first and then import them into Electrum. I don't think Electrum supports decrypting them, but it would be a nice feature for them to add.
The encrypted wallets should be BIP38 encrypted I'm guessing so you'll just need the password you originally encrypted them with which is separate from Electrum.
That article looks like it provides all the information you'll need to decrypt it. If you do plan to use a website such as bit2factor.org, you'll probably want to do it with an offline copy to ensure they don't log your keys.
Thanks. I know I downloaded the bitaddress.org generator offline when i created them on an Ubuntu USB stick minus internet but don't recall if it was BIP38 - I'm guessing whatever was the default. I have to put this on hold for a few days but fingers crossed decrypting via bit2factor.org (offline) works when i resume next week. I will update as I go along. (Money still there - yay!)
Speaking of key-logging - at some point everyone using Electrum etc are relying on
when they put aside concerns about key-logging etc? I didn't verify my download with the PGP sig (too complex) - in fact "too complex" was one of the top comments on Reddit by an expert type.... so at some level I am relying on the company's reputation that they are not going to run off with my private keys? Sort of like Chase not running off with my fiat money?
