User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:56.0) Gecko/20100101 Firefox/56.0
Build ID: 20171003100843

Steps to reproduce:

ECDSA keys exported via WebExpo to spki shall have the algo OID of "1.2.840.10045.2.1" as per https://www.w3.org/TR/WebCryptoAPI/#ecdsa-operations.

Currently, these keys have OID "1.3.132.112".


Actual results:

The OID is "1.3.132.112"


Expected results:

The OID shall be "1.2.840.10045.2.1".

Typo: s/WebExpo/WebCrypto/

The ecdh OID is also wrong as per https://github.com/w3c/webcrypto/issues/86

JC, P2 in Dom:Security requires someone to be assigned to it. Can you help me find either an assignee or alternatively we could change the priority. What do you think?

[J.C. Jones [:jcj] (he/they)]

Eventually I expect it will be Dana or me, but let's put it at P3 for now.

Note that while this bug may appear inconsequential, it actually prevents easily importing the key into other contexts like OpenSSL. The ASN has to be manually opened and fixed.

Thanks for the heads-up, kll, that's useful to know. With the updates from Bug 1564509 this is straightforward. I'll post a patch shortly.

Attachment: Bug 1410403 - Use id-ecPublicKey for ECDH key export from WebCrypto r?keeler

id-ecPublicKey is defined as the OID {iso(1) member-body(2) us(840)
ansi-x962(10045) keyType(2) ecPublicKey(1)}, and is the NSS default, so
remove the override code from CryptoKey.cpp that forced it to the legacy
id-ecDH code.
