📌 Hash Format

        
$bitcoin$<mkHexLen>$<mkHex>$<saltHexLen>$<saltHex>$<iterations>$...

Contoh:
$bitcoin$64$617c4b22fabd578e0f4d030245a0cbebd9da426fbee49c2feb885fa190b65096$16$dff2b89e4d885c28$35714$2$00$2$00

      mkHexLen=64 chars (32 bytes)                                   saltLen=16 chars       iterations


        
🔧 How to Extract Hash

⚙️ Verification Algorithm

        

          
1. KDF (Key Derivation): SHA-512 Iterative

          
hash = SHA512(password + salt)   ← round 1
hash = SHA512(hash)              ← rounds 2..N
key = hash[0..31], iv = hash[32..47]

          
2. Decryption: AES-256-CBC using key and iv from KDF

          
3. Validation: 16 last bytes of decrypted result must all be 0x10

        


        
📋 Batch Checking Tips

		

        
    
          
  • Upload .txt wordlist file directly using the "Upload .txt" button
    • 
          
  • Concurrency 2 is recommended — higher values may slow down the browser
    • 
          
  • Each hash with ~35000 iterations takes ~1-3 seconds per password
    • 
          
  • Use the Pause button if the browser feels sluggish
    • 
          
  • Export CSV to save all results
    •
