Just leaving this here:

.key extension was most commonly used with Multibit.

Trying to recover from an old blockchain.info (wallet.json.aes).

Know the password, managed to extract a 44 CHAR string as the private key.

But not clear to me this is the key base64 encoded - as a text decoding comes up as a mess, and hex comes out as 64 chars starting with f5: (listed in pairs, though only 64 chars without trailing zeros - e.g. counting 5 instead of 05)

Anyone have any idea what this is, and how I can convert this to a WIF?

Thanks

I have no experience personal recovering old wallets from blockchain.info, but if you ended up with a 64 character HEX, you might be on to something:

Private Key Hexadecimal (64 characters [0-9A-F]) (less common).
Example: CA9A061710B8BC582E1B8BB60D0F3F2751791888AB5C18737620087ABDF74A05

I'd try to enter this on the Wallet Details tab on an offline and air-gapped downloaded version of Bitaddress.org.

thanks. in case it helps anyone, it turns out that the old blockchain.info wallets encode the keys as BASE58 (RAW).

So just convert that from base58 to hex through any means and then generate a WIF  like through bitaddress.org

How about this: "do this offline!!"?

Sounds great! I know the old one probably would be good enough for most people but somehow you will always run into a comparateur assurance chien few slower ones like me

The only problem it won't show the latest data like transaction history or the current balance of that wallet.

That's not a problem, you don't need transaction data to extract private keys. By the time you're using an offline system for private key recovery, I assume you already know which addresses you're looking for.

I think bitaddress handles base 64 to wif as well. As has been said, use the offline version with a computer that is offline.

Hi everyone,
hope that here i get help.
i've imported old wallet.dat backup but the behavior looks strange to me. (i know the passphrase)
1. i see unknown transatcions with large amount (i have never had such amount of btc)
2. these transactions in overview are still unconfirmed despite blockchain download is beyond this point.

3. i don't event see spend or receivine addresses

i'm prety sure that something is wrong, but i don't know what.

thanks for help!

Any chance you've imported an altcoin wallet into Bitcoin Core? I've never tried it myself, but from what I've read, this is the most common mistake.
Common guesses: it could be either Litecoin or Dogecoin.

Bump: I've updated the mini-private-key section thanks to this post and Bitaddress.org.

If you want to recover an old JuBiter Wallet:

It is / was a clone / custom skin of the imkey wallet.

Don't think they did anything special with it.
