Pasteboard Viewer vs JSON Web Token

Inspect the system pasteboard while developing your app. This is a developer utility that lets you inspect the system pasteboard. This can be useful to ensure your app is putting the correct data on UIPasteboard. The app refreshes the pasteboard contents live and can preview text, RTF, images, and anything that has a Quick Look preview. Note that this is not a clipboard manager. If you're not an iOS developer, you probably don't want this app. It hides obsolete system pasteboard types that have modern equivalents. This includes `CorePasteboardFlavorType`, `NSStringPboardType`, `NSFilenamesPboardType`, etc. Known issue: When the app runs on visionOS in compatibility mode, the system may show a lot of “pasted” notifications. This is a system bug.

JSON Web Token is the fastest way to build, decode and verify JWTs on iPhone, iPad and Mac. Paste any token and instantly see its header and payload, neatly typed and editable. Sign your own tokens with the algorithm of your choice, verify signatures against your own keys, and copy the result with one tap. BUILD • Create tokens from scratch with editable header and payload fields • 12 signing algorithms: HS256/384/512, RS256/384/512, PS256/384/512, ES256/384/512 • One-tap generation of real random keys for every algorithm family VERIFY • Paste your own HMAC secret or public key to verify any token • Clear verified/invalid signature badge • Tamper with the payload and watch the signature react INSPECT • Typed values: strings, numbers, booleans, arrays, nested objects, null • JSON view with configurable indentation, ready to copy • Header and payload sizes in bytes • Date helper to convert timestamps for iat, exp and nbf claims Built for developers: no account, no tracking, everything stays on your device.
