You created vanity p2pkh-addresses in the past, you have access to the private keys (WIF) and addresses (1...).

Now you want to spend the funds securely and in an offline way (you do not want to enter your private key into an ONLINE computer).

I imagine something like:

  • You enter the p2pkh address (ONLINE), the program fetches the UTXOs and creates a list of transactions and an unsigned transaction to spend the inputs to a given address.
  • In the next step you can sign the transaction (OFFLINE) and export the signed transaction.
  • In the last step you submit the TX to the network.

Are there any user-friendly tools/programs that offer this functionality?

  • I believe this is how pretty much any offline wallet program works. You use the private-key-less online wallet to generate whatever is needed for the transaction, then you transport the transaction to the offline one to sign it

  • The big difference is that most offline wallet programs are using BIP39 HD wallets. Here I want to "solve" this problem for a dump private/public key pair.
