Ed25519 Key Generator
Generate a local Ed25519 key pair and copy it in the format your workflow expects

What It Generates
This page creates an Ed25519 key pair locally and shows the same material in compact hex, Base64URL, and JWK-style public-key form.
Generate and Copy a Key Pair
- Click Generate key pair for a fresh local key pair, or load the deterministic sample.
- Copy the private key only where you truly need it.
- Use the public key or JWK output in the next verification step.
Why the Formats Differ
The underlying key bytes are the same, but surrounding ecosystems expect different encodings. Hex is easy to diff, Base64URL fits token and JWK workflows, and JWK adds the metadata a JOSE toolchain expects.
