hash-generate

What This Skill Does

The hash-generate skill is a comprehensive utility for cryptographic hashing, encoding, decoding, and unique identifier generation. It serves as a bridge between the OpenClaw agent and the hash.agentutil.net API, allowing you to quickly perform standard operations like SHA-256 hashing, Base64 encoding/decoding, URL formatting, and HMAC generation without leaving your workspace. It also includes an intelligent identification tool that can analyze a given hash string to determine its likely algorithm, making it a critical tool for data integrity verification, security debugging, and basic payload obfuscation.

Installation

You can install the skill directly into your environment using the OpenClaw command-line interface. Simply run the following command in your terminal:

clawhub install openclaw/skills/skills/cutthemustard/hash-generate

Once installed, the skill will be automatically loaded into your agent's capability set, allowing you to invoke it using standard natural language requests.

Use Cases

• Security & Cryptography: Quickly generate file hashes to verify data integrity or create HMACs for API request signing.
• Data Transformation: Encode strings to Base64 or URL-safe formats for web transmission or decode incoming payloads for inspection.
• System Administration: Generate RFC 4122 compliant UUIDs for database entries or unique session tokens.
• Forensics: Use the identification endpoint to determine which hashing algorithm was used to generate an unknown signature found in configuration files.
• Developer Workflow: Integrate these functions into larger agent workflows for automated secret handling or checksum verification.

Example Prompts

1. "Hash the string 'OpenClawRocks' using SHA-512 and format it as a hex string."
2. "Encode the URL 'https://example.com/search?q=test' into a URL-safe format."
3. "Can you identify the algorithm for this hash: 5d41402abc4b2a76b9719d911017c592?"

Tips & Limitations

• Sensitive Data: This skill utilizes an external API. While the service does not store logs, you should exercise caution and avoid sending highly sensitive passwords, private keys, or PII unless you are certain of your security requirements.
• Rate Limits: The free tier is limited to 10 queries per day. For high-volume professional use, consider the paid tier which supports x402 protocol payments via USDC on the Base network.
• Algorithms: Ensure you check the documentation for supported algorithms (md5, sha1, sha256, sha512, crc32) before requesting a hash to avoid errors.
