Generatore e firmatario di chiavi Ed25519

Domande frequenti

Quick answers.

›Is it safe to generate keys in a browser?

Yes, this tool uses the `crypto.subtle` implementation provided by your browser to ensure cryptographically secure random number generation. The keys are processed entirely on your machine and are never sent to our servers.

›What is the difference between the seed and the private key?

A seed is a 32-byte value used to derive the key pair, while the private key is the expanded 64-byte format used for signing. Both must be kept secret to maintain the security of your identity.

›Can I use these keys for SSH or Git?

Yes, Ed25519 is widely supported by OpenSSH and Git providers like GitHub or GitLab. You may need to format the output into a specific `id_ed25519` file structure or use a conversion utility for compatibility.

›How do I verify a signature?

To verify a signature, you need the original message, the signature hex string, and the sender's public key. If the signature matches these components, it proves the message was not altered and was signed by that specific key holder.
