I've followed the advice found here and also on the Github article linked from that post, but I'm still having issues decrypted a wallet backup using the latest version of Bitcoin Wallet on Android (v5.26 released 7/28/17)

I was able to take the BIN file in question and import that between Bitcoin Android wallets, so I know the backup is not corrupted and the password works.

When I run the openssl enc -d -aes-256-cbc -a -in <filename> command, targeting the BIN backup file, it prompts for the password, which is inputted. The resulting decryption fails.

Is there a change made to the encryption algorithm that I'm not taking into account? Any/all help is appreciated.

Thank you

EDIT: To be clear, I also attempted the openssl command string found on the Github article, but that also fails (it includes the -md md5 parameter)

i managed to decrypt a backup by doing this :

openssl enc -d -aes-256-cbc -md md5 -a -in ./walletbackupfile > decrypted_wallet

however, i have not managed to getting at the private keys from the output.

i have tried wallet-tool dump --dump-privkeys --password=..pin

but it seems like no private keys are dumped in the output

i have also tried wallet-tool raw-dump --dump-privkeys --password=..pin

that seems to dump some encrypted private keys of some kind, but i am not sure how to proceed from there.

  • Brilliant, thank you.. I was naive and didn't follow each step from that Github link, but after loading the bitcoinj wallet-tool I was able to successfully dump the private keys.
