Kaspeak.net Backup Decryption

A simple CLI script for decrypting an exported Kaspeak.net backup.

What the script does

• Accepts:

  • an encrypted backup
  • the profile password

• Decrypts the data using the Kaspeak SDK.

• Shows formatted JSON that contains:

  • privHex — private key in hex
  • privDec — the same key in decimal form
  • subs — list of subscriptions
  • secrets — group and channel secrets

Requirements

• Node.js
• Installed kaspeak-sdk.
• Exported backup from Kaspeak.
• The password you used to protect your profile.

Getting a backup in Kaspeak.net

In the Kaspeak.net app:

1. Open the profile menu (avatar icon in the top right corner).
2. Select Export backup.
3. Enter your password.
4. The app will copy the backup to the clipboard.
5. Paste it into a text file, for example backup.txt, and save it.

Installing the script

It is assumed that Node.js is already installed (see the "Requirements" section).

Option 1: via git

git clone https://github.com/kaspeak/kaspeak-vault-decoder.git
cd kaspeak-vault-decoder
npm i

Option 2: via ZIP archive

1. Download the repository as a ZIP (button Code → Download ZIP).
2. Extract the archive to any folder.
3. Open this folder in a terminal/command prompt.
4. Run the command:

npm i

Running

Option 1: backup in a file

If you saved the backup in a file called backup.txt:

node decode-vault.js backup.txt your_password

Option 2: pass the string directly

Not very convenient, but possible:

node decode-vault.js "YOUR_BACKUP_STRING" your_password

Common errors

• Invalid password: incorrect password.

• Invalid Base62 or Empty Base62: corrupted or empty backup. Make sure you copied the entire string.

---

Important

• Never show the privHex and privDec output to anyone.
• Do not store decrypted data in publicly accessible locations.
• Everything the script outputs gives full access to your wallet and profile.
