Topic: How to properly validate a BIP38 paper wallet? (Read 225 times)

Let's call them Bitcoin address and BIP38 encrypted private key. The address isn't encrypted.

All good so far!

I suggest to only use the Compressed address, which is what bitaddress.org uses by default.

You'll only need the Private Key WIF Compressed to use your funds from the compressed address.

By default, it uses the compressed address. This reduces fees when you make a transaction.

If your wallet supports it (my phone wallet Mycelium does), you can import/sweep the BIP38 encrypted key directly and enter the password in your wallet.

This works too. Decrypting the BIP38 private key before importing/sweeping works in almost any wallet.

This is what I do too.
You could be even safer by using other software to decrypt the private key, so you don't rely on bitaddress only. I've used bitcoinpaperwallet.NOWSCAMMING.com for this, although I think it uses the same engine.

Before funding your paper wallet with high amounts, I suggest to make a small transaction first, and sweep it into a wallet to experience how it works. Fees aren't that high at the moment.
After this transaction your paper wallet can no longer be called "cold storage": create a new one.

The process of creating and validating a BIP38 wallet is still confusing to me.

So I go to bitaddress.org and generate a BIP38 encrypted wallet. This is all done offline via ubuntu usb drive.

Now I have the BIP38 public and private keys. So I print these.

In order to validate this wallet is functioning correctly, I use bitaddress.org's "wallet info" tab and enter the encrypted (6P...) private key on my paper wallet and passphrase.

Success. It opens a bunch of different addresses; the important ones I'm guessing are "Bitcoin Address" and "Bitcoin Address Compressed"

Also, "Private Key WIF 51 characters base58, starts with a '5'" and "Private Key WIF Compressed 52 characters base58, starts with a 'K' or 'L'".

I was under the impression that the "Bitcoin Address" was supposed to match the public key on my physical paper wallet, which goes along with the "Private Key WIF 51 characters base58, starts with a '5'".

However, I notice my physical paper wallets public address does not match the displayed "Bitcoin Address" from the "wallet info" tab. Instead the "Bitcoin Address Compressed" matches.

So if I were importing and sweeping this wallet onto a hot wallet, would I use the "Encrypted Private Key (6p...)" as seen on my physical paper wallet or the "Private Key WIF 51 characters base58, starts with a '5'" or "Private Key WIF Compressed 52 characters base58, starts with a 'K' or 'L displayed in the "wallet info" tab?

Furthermore, is opening the wallet under "wallet details" on bitaddress.org (offline) using the encrypted private key on my paper wallet and passphrase, and seeing the matching "Bitcoin Address Compressed" to the physical paperwallet's public key in my hand, enough to verify the wallet is functioning correct and to begin sending funds to?
