What this tool is good for
Ed25519 is a modern digital signature algorithm designed for strong security, good performance, and compact signatures. It is widely used in new applications and protocols.
This generator can create a random 32-byte Base64 seed and derive the corresponding Ed25519 public key and private key entirely in the browser.
How to use it
- Click Generate private key to create a random 32-byte Base64 seed.
- If you already have a seed, paste it in and click Derive public key.
- Use the generated public key for verification and the derived private key for signing workflows.
Input requirements
- The seed input must decode to exactly 32 bytes.
- The generated values are encoded as Base64 for copy-and-paste workflows.
- No key material is uploaded to the server.
