Ethereum BIP38 Key Compression Tool

This tool decrypts BIP38-encoded keys and outputs Ethereum-compatible addresses and keys in various formats, supporting both compressed and uncompressed keys.

Features

  • Decryption: Decrypts BIP38-encoded keys using a password.
  • Address Generation: Generates Ethereum addresses for both compressed and uncompressed keys.
  • Key Formats: Outputs public keys in hexadecimal, private keys in Wallet Import Format (WIF), and BIP38-encrypted private keys for both compressed and uncompressed keys.

User Input

  1. BIP38-encoded key: The encrypted private key in BIP38 format.
  2. BIP38 password: Password to decrypt the BIP38-encoded key.

Process Overview

Decryption

  1. Decrypt the BIP38 Key: Using the provided password, decrypt the BIP38-encoded private key.
  2. Generate Key Formats: From the decrypted private key, derive both compressed and uncompressed key formats.

Output

For each key format (compressed and uncompressed):

  • Address: Ethereum address derived from the public key.
  • Public Key (hex): Public key in hexadecimal format.
  • Private Key (WIF): Private key in Wallet Import Format.
  • Private Key (BIP38): BIP38-encrypted private key.

SetUp

python3 -m venv venv

  • source venv/bin/activate # On Windows: i want to go live on twitter to talk about this Bip39, Bip32, BIP44, Derivation path, how Entropy is used to get raw Binary, with binary checksum convert to word indexes to get bip39 Mnemonic....

Can you create a guide for me to explain then session it as a 1 hour of class. It just basically explaining then in a way that technical and people can understand..

  • pip install -r src/requirements.txt
  • python src/main.py

pip install bip38

Key Steps for Implementation

  1. Decrypting BIP38:

    • Use a library that supports BIP38 decryption, such as bip38 in JavaScript or pybitcointools in Python.

  2. Generate Ethereum Address:

    • Derive the Ethereum address by taking the Keccak-256 hash of the public key, excluding the first byte if the key is uncompressed, and using the last 20 bytes of the hash.

  3. Public Key Compression:

    • Convert the public key from uncompressed format (65 bytes) to compressed format (33 bytes) or vice versa, as needed.

  4. BIP38 Encryption:

    • Encrypt the private key back into BIP38 format for both compressed and uncompressed versions.

Example

After running the tool, you can expect output similar to the following for both key formats:

Uncompressed Address: 0x1234...abcd
Compressed Address: 0xabcd...1234
Public Key (Hex) Uncompressed: 04a1b2...1234
Public Key (Hex) Compressed: 02a1b2...abcd
Private Key (WIF) Uncompressed: 5HueC...abcdef
Private Key (WIF) Compressed: KwdMA...ghijk
Private Key (BIP38) Uncompressed: 6Pf...xyz
Private Key (BIP38) Compressed: 6Pf...uvw
