I have some sort of Bitcoin key my sister has saved since 2013. It is 239 characters long and starts with U2Fsd… My sister thinks she might have used the wallet https://play.google.com/store/apps/details?id=de.schildbach.wallet but can’t get it to work. Can you help me figure out what this key is?
Does it start “U2FsdGVkX1”?
If so that’s OpenSSL encrypted Base64 data, which decodes to “Salted_”.
It is almost certainly an encrypted master private key from “Bitcoin Wallet for Android” by Andreas Schildbach, which uses this encryption method and this file naming system. Have you used this app in the past? You will need to use that app to restore the file, and you will need to remember the encryption key/password you used.
Obviously the usual warnings apply: Do not trust anyone - especially those who suggests they can bruteforce for you - or wants access to your computer to fix it remotely.
Yes it does!
How can I generate the address and private key so I could get to the coins?
Above was from a quick search…
