Many consumers need SPKI support (X.509, TLS, QUIC, WebCrypto), each
with different ways to set signature parameters. SPKIs themselves can
get complex with id-RSASSA-PSS keys which come with various constraints
in the key parameters. This suggests we want a common in-library
representation of an SPKI.
This adds two new functions EVP_parse_public_key and
EVP_marshal_public_key which converts EVP_PKEY to and from SPKI and
implements X509_PUBKEY functions with them. EVP_PKEY seems to have been
intended to be able to express the supported SPKI types with
full-fidelity, so these APIs will continue this.
This means future support for id-RSASSA-PSS would *not* repurpose
EVP_PKEY_RSA. I'm worried about code assuming EVP_PKEY_RSA implies
acting on the RSA* is legal. Instead, it'd add an EVP_PKEY_RSA_PSS and
the data pointer would be some (exposed, so the caller may still check
key size, etc.) RSA_PSS_KEY struct. Internally, the EVP_PKEY_CTX
implementation would enforce the key constraints. If RSA_PSS_KEY would
later need its own API, that code would move there, but that seems
unlikely.
Ideally we'd have a 1:1 correspondence with key OID, although we may
have to fudge things if mistakes happen in standardization. (Whether or
not X.509 reuses id-ecPublicKey for Ed25519, we'll give it a separate
EVP_PKEY type.)
DSA parsing hooks are still implemented, missing parameters and all for
now. This isn't any worse than before.
Decoupling from the giant crypto/obj OID table will be a later task.

Although RFC 3279 allows both, per RFC 5912, keys must use a named curve
rather than spelling out the curve parameters. Although we do not allow
arbitrary curves, we do have to (pretty hackishly) recognize built-in
curves in ECPrivateKeys.
It seems the cause of this was that OpenSSL, unless you set asn1_flag on
the EC_GROUP, likes to encode keys by spelling out the parameters. This
is in violation of RFC 5915, though probably not in violation of one of
the other redundant ECC specifications. For more fun, it appears
asn1_flag defaults to *off* in the API and *on* in the command-line
tools.
I think the original cause was these defaults meant the pre-BoringSSL
Android/OpenSSL Chromium port wrote out Channel ID keys in this format.
By now this should no longer by an issue, but it'll warrant a bit more
investigation to be sure we can drop it.
For now, keep this logic out of SPKIs by not calling d2i_ECParameters.
d2i_ECParameters is a fairly pointless function when only named curves
are allowed. In testing other implementations, none of Firefox, Safari,
or IE11/Win will parse such certificates (i.e. the error is fatal and
unbypassable). Likewise, because Mac and Windows' underlying libraries
reject this, Chrome on Mac and Windows already rejects such things. Thus
this change should be compatible.

OpenSSL accepts both OID 2.5.8.1.1 and OID 1.2.840.113549.1.1.1 for RSA
public keys. The latter comes from RFC 3279 and is widely implemented.
The former comes from the ITU-T version of X.509. Interestingly,
2.5.8.1.1 actually has a parameter, which OpenSSL ignores:
rsa ALGORITHM ::= {
KeySize
IDENTIFIED BY id-ea-rsa
}
KeySize ::= INTEGER
Remove support for 2.5.8.1.1 completely. In tests with a self-signed
certificate and code inspection:
- IE11 on Win8 does not accept the certificate in a TLS handshake at
all. Such a certificate is fatal and unbypassable. However Microsoft's
libraries do seem to parse it, so Chrome on Windows allows one to
click through the error. I'm guessing either the X.509 stack accepts
it while the TLS stack doesn't recognize it as RSA or the X.509 stack
is able to lightly parse it but not actually understand the key. (The
system certificate UI didn't display it as an RSA key, so probably the
latter?)
- Apple's certificate library on 10.11.2 does not parse the certificate
at all. Both Safari and Chrome on Mac treat it as a fatal and
unbypassable error.
- mozilla::pkix, from code inspection, does not accept such
certificates. However, Firefox does allow clicking through the error.
This is likely a consequence of mozilla::pkix and NSS having different
ASN.1 stacks. I did not test this, but I expect this means Chrome on
Linux also accepts it.
Given IE and Safari's results, it should be safe to simply remove this.
Firefox's data point is weak (perhaps someone is relying on being able
to click-through a self-signed 2.5.8.1.1 certificate), but it does
further ensure no valid certificate could be doing this.
The following is the 2.5.8.1.1 certificate I constructed to test with.
The private key is key.pem from ssl/test/runner:

Normally this would be pretty scary:
if (...) {
} if (...) {

But it's an early return anyway.

It takes ownership of the buffer, so it's not actually const. The
const-ness gets dropped once it transits through EVP_PKEY_CTX_ctrl.
Also compare against INT_MAX explicitly for the overflow check. I'm not sure
whether the casting version is undefined, but comparing against INT_MAX matches
the rest of the codebase when transiting in and out of signed ints.

It's never used. It's not clear why one would want such a thing.
EVP_PKEY_CTX has no way for callers to register callbacks, which means
there shouldn't be a way for the library to present you an EVP_PKEY_CTX
out-of-context. (Whereas app_data/ex_data makes sense on SSL because of
its numerous callbacks or RSA because of RSA_METHOD.)
