encryption BIP38, and now no way to get the password.
Any chance I could recover it?
BIP38 encryption is very difficult to brute-force, it requires a lot of CPU power for each try. See
I'm BIP38 curious, please help me out! for instance, where a 1 Bitcoin reward (I think up to $1000 at the time) wasn't enough to crack a wallet with
6 random characters, even after giving a few hints.
Since then, CPU power got cheaper and Bitcoin got more expensive, but if you used any serious password, the
only way to recover your funds is if you can somehow remember the password. Maybe start with common passwords you've used at the time, possibly with small variations?
You can use
bitaddress.org (download it and run it from an offline LIVE Linux DVD) to securely try passwords without risking them to any possible malware on your system.
