Dev/testing use. Generated with crypto.subtle.generateKey + CSPRNG. For prod-critical keys prefer ssh-keygen / openssl in a locked-down env.
How to use.
- Pick RSA, EC or AES, then a size/curve.
- Press Generate — WebCrypto mints the key in this tab.
- Reveal the private key only to copy it, then Clear memory.
