Decode your prime

Recovered name

This is the normalized form used inside the cipher (accents may differ from how you type your name day to day).

Doesn't match the name on your certificate? Your key or prime is slightly off. a3.0 has no authentication tag, so a wrong key can still "succeed" and return scrambled letters — that's a deliberate teaching choice, not a broken prime. Real-world ciphers add a tag (like AES-GCM) to detect this.

Heads up — this result looks unusual. The decode succeeded, but the recovered text doesn't look like a typical name. Double-check the prime and key from your certificate; a single wrong character in the key produces gibberish.
