Ethernaut Scripts

Description

This repository contains Python automation scripts for solving Ethernaut levels:

1. Privacy_key_extractor.py – Fast automated extraction of the _key bytes for Level 12 – Privacy.
2. Gatekeeper_one.py – Generates a custom bytes8 key from your tx.origin address for Level 13 – GatekeeperOne.
3. pad_to_bytes32.py – Pads any hex string to a 32-byte (64-hex-char) zero-padded value, commonly used in AlienCodex level.

Features

• Privacy_key_extractor.py – Input the constructor bytecode; automatically extracts the _key bytes.
• Gatekeeper_one.py – Input your wallet address (tx.origin); generates a compliant bytes8 key.
• pad_to32_bytes.py – Input any hex string; returns a bytes32-padded version.

Usage

Privacy key extractor:

python Privacy_key_extractor.py

• Paste the constructor bytecode.
• Script outputs the _key bytes.

Gatekeeper key generator:

python Gatekeeper_one.py

• Input your wallet address starting with 0x.
• Script outputs your bytes8 key.

Pad hex to bytes32:

python pad_to32_bytes.py

• Input any hex string (0x optional).
• Script outputs the zero-padded 32-byte value.

Notes

• All scripts automate tasks used in Ethernaut levels.
• Privacy_key_extractor.py is for fast _key extraction, Gatekeeper_one.py is for custom key generation, and pad_to32_bytes.py is for bytes32 hex padding.
