Hash Generate

Hash, HMAC, encode/decode, UUID generation, and hash identification.

Compute hashes (MD5, SHA-1, SHA-256, SHA-512, CRC32), HMACs, encode/decode (base64, hex, URL), generate UUIDs, and identify unknown hash algorithms.

Data Handling

This skill sends user-provided input to an external API for processing. Do not send sensitive data (passwords, secrets, private keys) without explicit user consent. The service does not store or log input data beyond the immediate response.

Endpoints

Hash

bash

curl -X POST https://hash.agentutil.net/v1/hash \
  -H "Content-Type: application/json" \
  -d '{"input": "hello world", "algorithm": "sha256"}'

Algorithms: md5, sha1, sha256, sha512, crc32. Optional encoding: hex (default) or base64.

HMAC

bash

curl -X POST https://hash.agentutil.net/v1/hmac \
  -H "Content-Type: application/json" \
  -d '{"input": "hello", "key": "secret", "algorithm": "sha256"}'

Encode/Decode

bash

curl -X POST https://hash.agentutil.net/v1/encode \
  -H "Content-Type: application/json" \
  -d '{"input": "hello", "operation": "encode", "format": "base64"}'

Formats: base64, hex, url, uuid (encode-only, generates random UUID).

Identify Hash

bash

curl -X POST https://hash.agentutil.net/v1/identify \
  -H "Content-Type: application/json" \
  -d '{"hash": "2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824"}'
