Ok... so your private key(s) should look something like:
5Kb8kLf9zgWQnogidDA76MzPL6TsZZY36hWXMssSzNydYXYB9KF
and should start with a "5", an "L" or a "K".
NOTE: You need to make sure that there are no spaces in the key (hence the "omit spaces in key data" option!)... otherwise, most other wallets will reject your key as invalid. How you go about importing/sweeping them depends on the wallet you're attempting to import them into...
To
import into Electrum, you'd do the following:
1. Download and install Electrum from:
https://electrum.org/#download2. During first run, it will want to create a new wallet... give it a unique name if you want, or just go with "default_wallet" (if you've already run Electrum, open it and then select "File -> New\Open")
3. For wallet type... select "Import Bitcoin Addresses or Private Keys":
4. Copy/Paste your private keys... one per line...
5. Click the Next button and your "imported" wallet should be created and you should see your addresses, transactions and bitcoin balance.
To
sweep into Electrum:
1. Download and install Electrum from:
https://electrum.org/#download2. During first run, it will want to create a new wallet... give it a unique name if you want, or just go with "default_wallet" (if you've already run Electrum, open it and then select "File -> New\Open")
3. For wallet type... select "Standard Wallet"
4. Select "Create a new seed" and then following the instructions:
5. Once you've finished walking through the setup, goto "Wallet -> Private Keys -> Sweep"
6. Copy/Paste your private keys, one per line... and click next... Electrum will create a transaction that sends the coins from your OLD Armory keys, into your new Electrum wallet.
