Ya you're right here it is the DER-encoded SPKI and opaque ASN.1_subjectPublicKeyInfo is the right way to go.


Thanks,

Subject: [TLS] draft-ietf-tls-subcerts-01: some nits a question

Hi,

I submitted a PR to address some nits I noticed:
https://github.com/tlswg/tls-subcerts/pull/17

One question:

In s3, public_key is the same thing as RawPublicKey in RFC 7250, i.e., they are both DER-encoded SPKI from RFC5280? If it is, does it make sense to reuse:
opaque ASN.1_subjectPublicKeyInfo<1..2^24-1> ?
If not, shouldn’t
public_key<0..2^16-1>;
be
public_key<1..2^16-1>;
or
public_key<1..2^24-1>

spt
