PIPELINE Web Development Intermediate 2 steps

Decode URL and show hex bytes

When debugging URL-encoded payloads, you often need both the decoded text and its raw byte values. This chain decodes the percent-encoding first, then shows the uppercase hex representation — helpful for spotting invisible characters or encoding anomalies.

What it solves

Percent-decode a URL-encoded string then view its hexadecimal byte representation for low-level analysis.

How to Chain Encoding and Hashing Workflows

Real data-processing tasks rarely use a single tool. This tutorial shows how to compose encoding and hashing tools into multi-step pipelines: a base64-to-hash-to-hex verification chain, parallel multi-algorithm integrity checking, and an automatic encoding-format conversion chain. Each pattern maps to an existing workflow recipe (base64-encode-decode-verify, hmac-sign-verify) and explains when to use inline tool chaining versus a saved recipe.
