Wallet.dat Recovery – Extract Bitcoin from Damaged or Encrypted Core Wallets
Bitcoin Core wallets store your private keys in a file called wallet.dat. If this file becomes corrupted, encrypted with a forgotten password, or accidentally deleted, you may lose access to your funds. Wallet.dat recovery is the specialized process of extracting private keys from damaged, password‑protected, or incomplete wallet.dat files. At Crypto Reverse Transaction , we offer professional wallet.dat recovery using advanced file repair, password brute‑force, and key extraction techniques. Read our success stories and testimonials .
What Is Wallet.dat Recovery?
Wallet.dat recovery refers to retrieving cryptocurrency private keys from a Bitcoin Core wallet.dat file that is:
- Corrupted – The file structure is damaged due to disk errors or improper shutdown.
- Encrypted – You have the file but forgot the wallet password.
- Deleted – The file was accidentally deleted but may still be recoverable from disk.
- Incomplete – The file was partially overwritten or truncated.
Bitcoin Core wallet.dat files have been used since the early days of Bitcoin. Many old wallets contain significant value.
Can You Recover a Wallet.dat File?
Yes, through several methods:
- Undeleting – Use file carving to recover a deleted wallet.dat (if disk blocks not overwritten).
- Repairing corruption – Use specialized tools to fix header or data structure errors.
- Password recovery – Brute‑force or dictionary attack on an encrypted wallet.
- Extracting keys from damaged file – Even partial data may yield private keys.
We have successfully recovered wallet.dat files for hundreds of clients, with success rates over 90% for undamaged encrypted files (when password is guessable) and over 70% for minor corruption.
How Wallet.dat Recovery Works – Our Process
We follow a diagnostic and recovery methodology. Start with a free consultation via our case consultation page.
Step 1: Free Initial Consultation
Contact us through our contact us page. Describe:
- Do you have a wallet.dat file? (Yes/No/Partially)
- Is it encrypted? (Yes/No/Unknown)
- Do you remember any part of the password?
- What happened? (Deleted, corrupted, forgotten password)
Our experts assess recoverability within 24 hours at no cost.
Step 2: $99 Diagnostic & Analysis
For most individual cases, our diagnostic fee is $99. We:
- Analyze the wallet.dat file structure
- Determine encryption type (if any)
- Assess corruption level
- Provide a recovery plan and cost estimate
Timeline: 1‑2 business days.
Step 3: Recovery Execution
Option A – Undeletion
If the file was recently deleted and disk not overwritten, we use file carving software to recover it.
Option B – Corruption repair
We use tools like wallet.dat repair or hex editors to fix header or key‑value structure errors.
Option C – Password recovery (encrypted wallet)
We perform brute‑force or dictionary attacks based on your memory of the password (length, character types, probable words). Success depends on password complexity.
Option D – Direct key extraction from damaged file
Even if the file is partially corrupted, we may extract usable private keys using pywallet or custom scripts.
Step 4: Funds Accessible
Once private keys are extracted, you can import them into a new wallet (e.g., Electrum, Bitcoin Core) to access your funds. No recovery, no fee – success fee: 20% only if we succeed (where applicable; simple undeletion may be covered by diagnostic fee).
