Recovering Dimecoins From Android Wallet

We put our best effort into covering all topics related to Dimecoin. Each section will cover a different category.

This guide describes how you can use a backup file on a standard PC to recover your Dimecoins from the Android mobile app (v1.1.1). Normally, this shouldn’t be needed. It is much preferred to just use Options > Back up Keys > Restore Private Keys from within the Dimecoin Wallet app if you can. This guide is only meant for rare cases:

  • Your Android device is destroyed or missing and you do not want or cannot get a new Android device.
  • Legislation in your country forbids you to continue using the app and you missed the chance to move your coins out while it was still legal.
  • The app suddenly goes out of service for whatever reason. This event is extremely unlikely,however, is plausible.

Be aware some of the steps in this tutorial require handling your private keys in the unencrypted form. Do not expose them to anyone. Whoever knows your private keys can spend your coins on these keys. It’d good practice that after you are finished handling these keys, they should be considered compromised, even if they are not. Make sure your system is free of any malware.

We recommend using Ubuntu Linux. You can boot from a Live CD if you want, but if you do, please refrain from sending your coins to a temporary wallet created in that environment, which would be lost e.g. on a power outage or computer failure. Your desired destination wallet should already be set up and you should have one of its receiving addresses or a QR code at hand.

Alternatively, you can also use Windows cmd shell or Powershell. Open Windows Search, search for and start Command Prompt or Windows Powershell. You will need administrator privledges so make sure you right click Run as administrator.

You should be at least a bit familiar with the Linux and shell commands. Commands in fixed-width font like this are meant to be executed as a shell command. Before you execute each command by pressing return, make sure to understand what it does or if will need to adjust some file or directory names. Commands starting with sudo apt will ask for your permission to install software by requiring your Ubuntu user password.



On your PC, within your Linux shell, install the following Ubuntu packages if missing:

sudo apt install openjdk-8-jdk android-tools-adb openssl git gradle

Windows (Installing OpenSSL with Powershell and Chocolatey)

On your PC, within Powershell, you will need to install openSSL if it has not previously been installed. This tutorial will use Chocolatey as a package manager. Assuming you have Chocolately installed, your first task will be to install OpenSSL on Windows. (If not, you can use these installation instructions as a guide).

Once Chocolatey is installed, open up your PowerShell console and run the command:

choco install OpenSSL.Light

Android Device

On your Android device, go to Settings > Developer Options and enable “USB debugging”. On most recent devices you will need to first go to Settings > About and tap on the device’s “Build number” multiple times until you see the “You are now a developer” message.

Locating the Backup Files

If you followed the app’s guidance, your backup files will be located on a share of the storage access framework, very likely Google Drive or OneDrive. Watch out for filenames starting with dimecoin-wallet-keys-. The date the key was created will be appended to the end of the file name in this format (YYYY-MM-DD).

Alternatively, the backup can also be saved to your email account (as a file attachment of an email sent to yourself) or on your SD card in the /Download folder. Once located, move the backup file to your PCs desktop.

Decrypting Your Keys

You now have your backup file on your PC. Wallet backups are encrypted. Let’s decrypt it using the following command in your Windows shell (For Linux, replace desktop with the file location of your keys on your system):

openssl enc -d -aes-256-cbc -md md5 -a -in desktop/Dimecoin-wallet-keys-YYYY-MM-DD 

It will ask you for a decryption password, which is your backup password. If it prints “bad password” you’ve got the wrong password, but if it doesn’t print anything your password might still be wrong. Your keys should print in the command shell if the password is input properly.

If it prints something else or nothing, you likely didn’t get the password right. Passwords are case sensitive, and make sure you didn’t accidentally type a space character in front or after the password.

Recovering Your Coins and Importing into Desktop Wallet

You’ll see each line contains a key in WIF (wallet import format), technically Base58. The datetime string after each key is the birthdate of that key which you can ignore for the purpose of this one-time recovery.

You can import each individual key into a PC wallet like Windows 64 or Mac using the debug console (located under Tools on the topbar menu).

Using the debug console of the desktop wallet you do the following:

If encrypted, unlock it by entering

walletpassphrase "YourPassphrase" 600

This will unlock the wallet for 600 seconds (for example). You can input anytime you want (in seconds). Then use the command:

importprivkey yourprivatekey

Note: Be sure to replace yourprivatekey with the private key you derived from the steps above.

A rescan has to occur for your balance to reflect properly, which should occur automatically.

As soon as you see your whole balance again, empty your entire wallet to the desired destination wallet. You will need to import each private key from your Android wallet individually. Please do not continue to use the imported wallet. Remember you just operated on unencrypted keys which can be dangerous, so it’s good practice to handle them as if they were compromised, even if they were not.
