Created attachment 479067 [details] cryptokey-indexeddb-repro.html STEPS TO REPRODUCE: 1. Open the attached HTML file in Safari 2. Observe console output EXPECTED: - crypto.subtle.generateKey() generates a CryptoKey - key is stored in IndexedDB via put() - key is retrieved via get() - loaded key is the same CryptoKey object ACTUAL: After IndexedDB put/get roundtrip, get() returns null for X25519 non-extractable keys. AES-GCM non-extractable keys appear to work correctly. FREQUENCY: 100% reproducible on tested Safari versions. VERSION: Safari 26.4 (macOS 15.4) See also: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/26.4 Safari/605.1.15 TEST CASE: See attached cryptokey-indexeddb-repro.html
