crc32

Compute the CRC-32 (IEEE) checksum of UTF-8 text — the algorithm used by zip/gzip/PNG. Returns the unsigned 32-bit value and its hex form. Keyless, offline. (Error-detection checksum, not cryptographi

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("crc32", {});
ask_pipeworx 
// Or ask in plain English:
const answer = await px.ask("compute crc-32 (ieee, zip/gzip/png) and adler-32 (zlib) checksums of text");
