Maybe this should change the version to 0.2.0, since it's an api-breaking change?

[rjzak]

attest() how gets a Vec<CertReq> and returns Output, with updated tests, and removed content type check (and removed the two tests pertaining to content type checking).

[rjzak]

Should this be moved to the top of attest() so that all certs have the same Validity?

let now = SystemTime::now();
let end = now + Duration::from_secs(60 * 60 * 24 * 28);
let validity = Validity {
    not_before: Time::try_from(now).or(Err(ISE))?,
    not_after: Time::try_from(end).or(Err(ISE))?,
};

@npmccallum added a unit test to make sure attest() works with multiple CertReq objects, and responds with the same amount of Certficiate objects.

Passing reviews to someone else.

@rjzak see rjzak#1 for suggested approach cleaning this up

I missed this.
@rjzak could you make validity a parameter to attest_request? Then LGTM
