are confirmed, you're done and you can skip the next paragraph to EPILOGUE.
+You can also get a list of the private keys. If your wallet has a spending PIN set you need to decrypt it first, otherwise the private keys won't appear. Note that when you decrypt the wallet *the private keys can be accessed (and your Bitcoins stolen) by anyone with access to the system*, including malware or other users. Unless you fully trust the security of the computer consider running it on an offline system with no network connectivity.
+
+ ./wallet-tool decrypt --wallet=/tmp/bitcoin-wallet-decrypted-backup --password=<PIN>
+
+Then to get the private keys use:
+
+ ./wallet-tool dump --wallet=/tmp/bitcoin-wallet-decrypted-backup --dump-privkeys
+
+Look for `priv WIF=<...>`, where `<...>` will be your private keys in wallet import format. Be careful where you put them, as anybody getting access to them will be able to steal your coins. Consider securely deleting the decrypted wallet once you get your private keys.
## RECOVERING FROM BASE58 KEY FORMAT
FILES
Your wallet contains your private keys and various transaction related metadata. It is stored in app-private storage:
Mainnet: /data/data/de.schildbach.wallet/files/wallet-protobuf
Testnet: /data/data/de.schildbach.wallet_test/files/wallet-protobuf-testnet
The wallet file format is not compatible to wallet.dat (Satoshi client). Rather, it uses a custom protobuf format which should be compatible between clients using bitcoinj.
Certain actions cause automatic rolling backups of your wallet to app-private storage:
Mainnet: /data/data/de.schildbach.wallet/files/key-backup-protobuf
Testnet: /data/data/de.schildbach.wallet_test/files/key-backup-protobuf-testnet
Your wallet can be manually backed up to and restored from external storage:
Mainnet: /sdcard/Download/bitcoin-wallet-backup-<yyyy-MM-dd>
Testnet: /sdcard/Download/bitcoin-wallet-backup-testnet-<yyyy-MM-dd>
If you want to recover coins from manual backups and for whatever reason you cannot use the app itself to restore from the backup, see the separate README.recover.md guide.
The current fee rate for each of the fee categories (economic, normal, priority) is cached in app-private storage:
Mainnet: /data/data/de.schildbach.wallet/files/fees.txt
Testnet: /data/data/de.schildbach.wallet_test/files/fees-testnet.txt
