The process of searching for and extracting encrypted private keys from a wallet file can be complex and requires a deep understanding of the file format and encryption methods used.

In the case of Bitcoin, the private keys are stored in an encrypted format known as the Wallet Import Format (WIF). The private key is encrypted using a passphrase, and the resulting encrypted key is then stored in the wallet file.

To extract the encrypted private keys, you would need to search the wallet file for the specific bytes that indicate the start of an encrypted private key. The exact bytes will depend on the encryption method used and the specific wallet software.

Once you have identified the start of an encrypted private key, you can then move forward in the file to extract the bytes that make up the key. The length of the key will also depend on the encryption method used and the specific wallet software.

It's worth mentioning that searching for the private key by bytes is not a recommended practice, as the format and structure of the wallet files may change with a different versions of the software or with different wallets. Also, it's crucial to have a good understanding of the encryption method and its implementation to avoid leaking private keys or compromising security.

Additionally, attempting to extract private keys from a wallet file without proper knowledge and understanding of the encryption methods used can result in the loss of access to your funds. It's highly recommended to use official or well-vetted libraries or tools to access or manage the private keys.

Got it!

Look for "ckey!", before this there are 4 bytes b'\x27\x00\x01\x04' - before that there are 48 bytes of ckey (which consists of encrypted private key).

Hi All,

I am getting private keys from decrypted wallets by searching the wallet.dat file with keyhunter for b'\x01\x30\x82\x01\x13\x02\x01\x01\x04\x20' bytes.

But what I want to do is dump all encrypted private keys in the same way - search for some magic bytes and then move forward/backward and dump bytes with encrypted private key.
They should be in ckey as I understand.

How can I do that? What bytes to search for and which to dump?
