hash

Compute a cryptographic hash (hex digest) of text: algorithm = md5, sha1, sha256 (default), sha384, or sha512. Keyless/offline; the input is not stored or transmitted. MD5/SHA-1 are legacy (checksums

No parameters required.

Test with curl

The gateway speaks JSON-RPC 2.0 over HTTP POST. You can test any pack directly from the terminal.

Use with the SDK

Install @pipeworx/sdk to call tools from any TypeScript/Node project.

TypeScript 
import { Pipeworx } from '@pipeworx/sdk';
const px = new Pipeworx();
const result = await px.call("hash", {});
ask_pipeworx 
// Or ask in plain English:
const answer = await px.ask("compute md5 / sha-1 / sha-256 / sha-384 / sha-512 hashes and hmacs of text (keyless, offline, webcrypto + inlined md5)");
