Frequently Asked Questions
RSA, EC, or oct?
RSA for broad compatibility, EC for compact modern keys, oct for shared secrets.
What key size?
2048-bit RSA minimum mainstream; 256-bit EC roughly equivalent.
What are kid and alg?
Key ID for lookup plus algorithm declaration — both embedded in the JWK.
Is my key material uploaded anywhere?
No — generation uses browser cryptography locally, free with no signup.
