Steps to reproduce: // PKCS8 representation of a private P-384 EC key with the public key omitted const pkcs8 = new Uint8Array([48, 78, 2, 1, 0, 48, 16, 6, 7, 42, 134, 72, 206, 61, 2, 1, 6, 5, 43, 129, 4, 0, 34, 4, 55, 48, 53, 2, 1, 1, 4, 48, 32, 52, 118, 9, 96, 116, 119, 172, 168, 251, 251, 197, 230, 33, 132, 85, 243, 25, 150, 105, 121, 46, 248, 180, 102, 250, 168, 123, 220, 103, 121, 129, 68, 200, 72, 221, 3, 102, 30, 237, 90, 198, 36, 97, 52, 12, 234, 150]) crypto.subtle.importKey('pkcs8', pkcs8, { name: 'ECDSA', namedCurve: 'P-384' }, false, ['sign']) Actual result: importKey is rejected with DataError: Data provided to an operation does not meet requirements Expected result: EC private key PKCS8 without the public key component should import as in other browsers and Web Cryptography API implementations (we expect interoperability in this regard)

Using this in console for all browsers, I get similar error; const pkcs8 = new Uint8Array([48, 78, 2, 1, 0, 48, 16, 6, 7, 42, 134, 72, 206, 61, 2, 1, 6, 5, 43, 129, 4, 0, 34, 4, 55, 48, 53, 2, 1, 1, 4, 48, 32, 52, 118, 9, 96, 116, 119, 172, 168, 251, 251, 197, 230, 33, 132, 85, 243, 25, 150, 105, 121, 46, 248, 180, 102, 250, 168, 123, 220, 103, 121, 129, 68, 200, 72, 221, 3, 102, 30, 237, 90, 198, 36, 97, 52, 12, 234, 150]) crypto.subtle.importKey('pkcs8', pkcs8, { name: 'ECDSA', namedCurve: 'P-384' }, false, ['sign']) ___ Safari 17.4, Chrome Canary 124 and Firefox Nightly 125.

Actually I might have copied code wrong in Chrome: const pkcs8 = new Uint8Array([48, 78, 2, 1, 0, 48, 16, 6, 7, 42, 134, 72, 206, 61, 2, 1, 6, 5, 43, 129, 4, 0, 34, 4, 55, 48, 53, 2, 1, 1, 4, 48, 32, 52, 118, 9, 96, 116, 119, 172, 168, 251, 251, 197, 230, 33, 132, 85, 243, 25, 150, 105, 121, 46, 248, 180, 102, 250, 168, 123, 220, 103, 121, 129, 68, 200, 72, 221, 3, 102, 30, 237, 90, 198, 36, 97, 52, 12, 234, 150]) crypto.subtle.importKey('pkcs8', pkcs8, { name: 'ECDSA', namedCurve: 'P-384' }, false, ['sign']) __ It shows `Promise <pending>`.
