Agent skill

AES Key Brute-forcer with State Persistence and Throttling

Generates a Python script to brute-force an AES key derived from the product of two integers. The script includes logic for validating decrypted text against a known pattern, pausing execution periodically to cool the CPU, and saving/restoring state to allow resuming the brute-force process.

# AES Key Brute-forcer with State Persistence and Throttling Generates a Python script to brute-force an AES key derived from the product of two integers. The script includes logic for validating decrypted text against a known pattern, pausing execution periodically to cool the CPU, and saving/restoring state to allow resuming the brute-force process. ## Prompt # Role & Objective You are a Python Cryptography Assistant. Your task is to write a Python script that brute-forces an AES key derived from the product of two integers. The script must include specific features for CPU throttling and state persistence. # Operational Rules & Constraints 1. **Brute-Force Logic**: - Iterate through pairs of integers `i` and `j` within a specified range (e.g., 20-bit numbers: `range(1 << 20, 1 << 21)`). - Calculate the product `k = i * j`. - Filter `k` based on bit length constraints (e.g., `40 <= k.bit_length() <= 42`). - Derive the AES key by hashing `k` using SHA-256: `sha256(str(k).encode()).digest()`. - Decrypt the provided ciphertext using AES in ECB mode (`AES.MODE_ECB`). 2. **Validation**: - After decryption, check if the resulting plaintext contains a specific substring pattern (e.g., `

What does the AES Key Brute-forcer with State Persistence and Throttling skill do?

Generates a Python script to brute-force an AES key derived from the product of two integers. The script includes logic for validating decrypted text against a known pattern, pausing execution periodically to cool the CPU, and saving/restoring state to allow resuming the brute-force process.

How do I install it?

Run `npx skills add ECNU-ICALK/AutoSkill --skill aes-key-brute-forcer-with-state-persistence-and-throttling --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.

Where does this skill come from?

From ECNU-ICALK/AutoSkill, a repository with 539 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.

Is a popular skill a good skill?

Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
