e49197f15eef ("pki: Don't generate negative random serial numbers in
X.509 certificates") causes the value to become zero.  So the encoded
ASN.1 integer will start with a zero byte, which is only correct if the
integer would otherwise be interpreted as negative, i.e. the next byte
starts with the most significant bit set.  If that isn't the case, the
encoding is technically invalid and might get rejected by strict parsers.

Note that e49197f15eef did not actually fix a violation of RFC 5280 as
asn1_integer() assumes all passed numbers are positive and automatically
adds a zero prefix if the MSB is set.  What it did instead (or at least

number in two's complement. The difference can be seen in the output of

The reason is that OpenSSL only does the latter if the number fits into a
signed `long` variable, which isn't the case if a positive 64-bit number
has the MSB set (i.e. has a zero prefix) as it would be interpreted as
negative number in two's complement.  OpenSSL does print negative serial
numbers (even if it's a violation of the RFC), but only if they were
encoded as such, i.e. if there was no zero prefix:

2 years agoopenssl: Remove workaround for Brainpool ECDH curves for older OpenSSL versions

openssl: Remove workaround for Brainpool ECDH curves for older OpenSSL versions

Using the workaround with the EVP interface, which we use to derive shared
keys since 74e02ff5e624 ("openssl: Mainly use EVP interface for ECDH"),
would actually require us to register the OIDs of these curves as NID.
Otherwise, the two EC_GROUPs used by private and public key objects
are not considered the same and the key derivation fails.

Since the curves are supported by OpenSSL since 1.0.2 it's probably rare to
find a version without them nowadays.  One exception is the old BoringSSL
version we still use on Android, which defines the NIDs but not the curve
data.  However, that version also lacks support to register OIDs as NIDs,
so the only option to support these groups there would be to got back to not
using the EVP interface, which isn't in anyone's interest.  If there really
is a need for them there, we could probably patch BoringSSL or use OpenSSL.
