PKCS#8 (“PRIVATE KEY”) and SPKI (“PUBLIC KEY”) are the standard containers OpenSSL, Java, Go and WebCrypto read. JWK is the JSON form used by JOSE/JWT libraries. The fingerprint is the SHA-256 of the SPKI bytes. Keys come from the browser’s cryptographic random generator (RSA via WebCrypto, curves via the audited noble-curves library).
