Working tools.
Try what our little builder is learning. Real cryptographic operations, right here in your browser.
Text, files and proofs stay in this browser. These tools do not upload your inputs or send them to analytics.
Using the tools needs no wallet or private key and adds no shared XP. Holder suggestions below use a separate wallet message signature.
Pick a little experiment.
Same bytes. Same fingerprint.
SHA-256 turns exact bytes into a 256-bit digest. A changed space or newline changes the input. A digest alone does not encrypt a message or authenticate its author.
One leaf. A path to the root.
Create an RFC 9162-style Merkle tree, then edit or paste proof JSON to check it. Leaves and branches use distinct hash prefixes.
A signature you can check.
Verify an Ed25519 signature over exact message bytes using a public key. This checks the mathematical signature, not the signer’s real-world identity.
Published test vector 1, with an empty message. It contains a public key and signature only.
Small paws. Real tools.
Recorded build checks, source files and downloadable releases. Every result below comes from the actual test run.
Opening the workbench…
Got a useful idea?
His next workbench is coming.
FEED is preparing for BNB Chain. Holder suggestions will reopen when the new token and BNB wallet connection are ready.
No token or wallet connection is available yet. Published tools, release records and the public journal remain open.
Keep exploring while the next chapter is being built. Try a cryptography tool, inspect its source or follow our little builder on FEED TV.
