# Hash text (SHA family)

`POST /v1/tools/hash`

## Request

- Base URL: `https://mcp.cleanor.app`
- URL: `https://mcp.cleanor.app/v1/tools/hash`
- Auth: none declared

Compute a cryptographic hash of text (SHA-1, SHA-256, SHA-384 or SHA-512) and return the hex digest. Use for checksums, cache keys, or verifying content. MD5 is intentionally not offered (broken, and unavailable in Web Crypto). LLMs cannot compute these reliably by hand, so always use this tool instead of guessing.

## Request body

- object
  - `input` string, required: Text to hash (UTF-8).
  - `algorithm` 'sha-256' | 'sha-1' | 'sha-384' | 'sha-512': Hash algorithm. Default sha-256.

## Response `200`

Tool result: `data` (structured) and `text` (human-readable).

- ToolResult
  - `ok` boolean
  - `tool` string
  - `data` object, nullable
  - `text` string
  - `attribution` string

## Other responses

- `400`: Invalid arguments.
- `429`: Rate limited (120 requests per minute per IP).
