Question 1

What key sizes are available?

Accepted Answer

2048-bit and 4096-bit. 2048-bit is sufficient for most use cases. 4096-bit provides extra security but takes longer to generate.

Question 2

How are keys generated?

Accepted Answer

Keys are generated using the Web Crypto API with RSA-OAEP algorithm and SHA-256 hash. This is cryptographically secure.

Question 3

What format are the keys exported in?

Accepted Answer

Keys are exported in PEM format (Base64-encoded DER with headers). Public key uses SPKI format, private key uses PKCS8 format.

Question 4

Can I use these keys in production?

Accepted Answer

Yes. The Web Crypto API generates production-quality RSA keys. However, protect your private key carefully.

Question 5

Is my private key stored anywhere?

Accepted Answer

No. All key generation happens in your browser. Your private key never leaves your device.
