I am sweeping some outdated bitcoin wallets and I’ve two recordsdata named
- “Bitcoin Pockets backup” from 2020
- “bitcoin-wallet” from 2013
I’ve efficiently recovered the primary backup file by restoring it in Bitcoin Pockets (Android) utilizing an Android emulator. I may have additionally recovered it utilizing the bitcoinj CLI instruments described in this restoration information, and have since realized it was within the bitcoinj protobuf format.
I assumed the second file may be the older BASE58 format, additionally described within the restoration information, however it’s one other binary format. Neither Bitcoin Core, Electrum, or Bitcoin Pockets (Android) understands the file and so they all error when I attempt to open or restore it.
Digging contained in the file reveals some ASCII textual content like primary, which is presumably the pockets title, and 278 cases of ckey!, which this reply suggests are encrypted non-public keys.

Can anybody inform me what format this file may be? And if it is attainable to decrypt or examine the non-public keys? I am going to replace if I study any extra. Thanks!
