            Bug ID: 156114
           Summary: WebCrypto can generate but fails to export
                    RSA-OAEP-256 keys
    Classification: Unclassified
           Product: WebKit
           Version: Safari Technology Preview
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: roustem at agilebits.com

crypto.webkitSubtle.generateKey({
            name: "RSA-OAEP",
            modulusLength: 2048,
            publicExponent: new Uint8Array([0x01, 0x00, 0x01]),
            hash: {name: "SHA-256"}
        }, true, ["encrypt", "decrypt" ]).then((keypair) => {
            console.log("Generated Key Pair:", keypair);
            return crypto.webkitSubtle.exportKey("jwk", keypair.publicKey);
        }).then((keydata) => {
            console.log("Key Data:", keydata);
        }).catch((error) => {
            console.log("Error: ", error);
        });


The code above should be able log both the newly Generated Key Pair and also log the Key Data.

It successfully generates the key pair:

[Log] Generated Key Pair: – KeyPair {publicKey: Key, privateKey: Key}
KeyPair {publicKey: Key, privateKey: Key}KeyPairprivateKey: Key {type: "private", extractable: true, algorithm: Object, usages: ["decrypt", "encrypt"]}KeypublicKey: Key {type: "public", extractable: true, algorithm: Object, usages: ["decrypt", "encrypt"]}KeyKeyPair Prototype

But not able to export it:

[Log] Error: 
TypeError: Key algorithm and size do not map to any JWK algorithm identifier
