How to build a recipe
- 1
Paste input
Paste a token, ciphertext, encoded string, or plaintext into the input area.
- 2
Add steps
Add encoding, hashing, KDF, or encryption steps from suggestions or the operation library.
- 3
Tune parameters
Fill in keys, passphrases, salt, IV, and iteration counts for HMAC, PBKDF2, or AES-GCM.
- 4
Inspect the trace
Review each step output to find the layer that needs adjustment.
Features Overview
Crypto Workbench is a browser-side workspace for encoding, decoding, hashing, HMAC, PBKDF2, and AES-GCM. Build repeatable recipes to inspect JWTs, Base64URL, URL encoding, Hex, HTML entities, and encrypted envelopes.
Tool Description
A local-first encoding and cryptography workbench. Combine Base64/Base64URL, Hex, URL, HTML, JWT, SHA, HMAC, PBKDF2, and AES-GCM operations into repeatable recipes without uploading keys or input.
Capabilities Checklist
- Convert Base64, Base64URL, Hex, URL, and HTML entities in both directions.
- Decode JWTs and run SHA digests, HMAC-SHA256, PBKDF2-SHA256, and AES-GCM.
- Configure salt, IV, iterations, and output length with random salt / IV generation.
- Run recipes step by step with intermediate output, errors, and warnings.
- Everything runs in the browser; inputs and keys are not uploaded.
