Hello,

I’m having this strange problem, I hope someone can help me figure it out.

I found an old backup private key from 2013 backed up from android app, here is the:
https://play.google.com/store/apps/details?id=de.schildbach.wallet

I downloaded the new android version and attempted to import the key, I got an error message saying unreadable wallet. Because I think it was backup up based on the old BASE58 KEY FORMAT not the new PROTOBUF WALLET FORMAT that was introduced May 2014

Password is correct, because I went on to decrypt the file with openssl and I got four private keys, and I imported these private keys to Electrum I got all the addresses from that account except one is missing, and the reason I know that one address is missing is because I had a screenshot with the backup showing the right addresses and they are all there except one and of course it’s the one with bitcoins in it.
The OpenSSL command that I used is:

openssl enc -d -aes-256-cbc -a -in bitcoin-wallet-backup-2017-09-28 -out decrypted -md md5

Also I have to mention that the backup file is dated after the creation of the missing address, so it should be on the encrypted key, but I’m not sure why it’s not.

I hope someone can help me with this weird problem

Thank you in advance
