The internal use of tls.parseCertString was removed in
a336444c7f. The function does not handle
multi-value RDNs correctly, leading to incorrect representations and
security concerns.
This change is breaking in two ways: tls.parseCertString is removed
(but has been runtime-deprecated since Node.js 9) and
_tls_common.translatePeerCertificate does not translate the `subject`
and `issuer` properties anymore.
This change also removes the recommendation to use querystring.parse
instead, which is similarly dangerous.

Previously, Node.js incorrectly accepted uniformResourceIdentifier (URI)
subject alternative names in checkServerIdentity regardless of the
application protocol. This was incorrect even in the most common cases.
For example, RFC 2818 specifies (and RFC 6125 confirms) that HTTP over
TLS only uses dNSName and iPAddress subject alternative names, but not
uniformResourceIdentifier subject alternative names.
Additionally, name constrained certificate authorities might not be
constrained to specific URIs, allowing them to issue certificates for
URIs that specify hosts that they would not be allowed to issue dNSName
certificates for.
Even for application protocols that make use of URI subject alternative
names (such as SIP, see RFC 5922), Node.js did not implement the
required checks correctly, for example, because checkServerIdentity
ignores the URI scheme.
As a side effect, this also fixes an edge case. When a hostname is not
an IP address and no dNSName subject alternative name exists, the
subject's Common Name should be considered even when an iPAddress
subject alternative name exists.
It remains possible for users to pass a custom checkServerIdentity
function to the TLS implementation in order to implement custom identity
verification logic.
This addresses CVE-2021-44531.

This change introduces JSON-compatible escaping rules for strings that
include X.509 GeneralName components (see RFC 5280). This non-standard
format avoids ambiguities and prevents injection attacks that could
previously lead to X.509 certificates being accepted even though they
were not valid for the target hostname.
These changes affect the format of subject alternative names and the
format of authority information access. The checkServerIdentity function
has been modified to safely handle the new format, eliminating the
possibility of injecting subject alternative names into the verification
logic.
Because each subject alternative name is only encoded as a JSON string
literal if necessary for security purposes, this change will only be
visible in rare cases.

This introduces TLS1.3 support and makes it the default max protocol,
but also supports CLI/NODE_OPTIONS switches to disable it if necessary.
TLS1.3 is a major update to the TLS protocol, with many security
enhancements. It should be preferred over TLS1.2 whenever possible.
TLS1.3 is different enough that even though the OpenSSL APIs are
technically API/ABI compatible, that when TLS1.3 is negotiated, the
timing of protocol records and of callbacks broke assumptions hard-coded
into the 'tls' module.
This change introduces no API incompatibilities when TLS1.2 is
negotiated. It is the intention that it be backported to current and LTS
release lines with the default maximum TLS protocol reset to 'TLSv1.2'.
This will allow users of those lines to explicitly enable TLS1.3 if they
want.
API incompatibilities between TLS1.2 and TLS1.3 are:
- Renegotiation is not supported by TLS1.3 protocol, attempts to call
`.renegotiate()` will always fail.
- Compiling against a system OpenSSL lower than 1.1.1 is no longer
supported (OpenSSL-1.1.0 used to be supported with configure flags).
- Variations of `conn.write('data'); conn.destroy()` have undefined
behaviour according to the streams API. They may or may not send the
'data', and may or may not cause a ERR_STREAM_DESTROYED error to be
emitted. This has always been true, but conditions under which the write
suceeds is slightly but observably different when TLS1.3 is negotiated
vs when TLS1.2 or below is negotiated.
- If TLS1.3 is negotiated, and a server calls `conn.end()` in its
'secureConnection' listener without any data being written, the client
will not receive session tickets (no 'session' events will be emitted,
and `conn.getSession()` will never return a resumable session).
- The return value of `conn.getSession()` API may not return a resumable
session if called right after the handshake. The effect will be that
clients using the legacy `getSession()` API will resume sessions if
TLS1.2 is negotiated, but will do full handshakes if TLS1.3 is
negotiated. See https://github.com/nodejs/node/pull/25831 for more
information.

Make the deprecated `tls.createSecurePair()` method use other public

Since `tls.createSecurePair()` has been runtime-deprecated only
since Node 8, it probably isn’t quite time to remove it yet,
but this patch removes almost all of the code complexity that
is retained by it.
The API, as it is documented, is retained. However, it is very likely
that some users have come to rely on parts of undocumented API
of the `SecurePair` class, especially since some of the existing
tests checked for those. Therefore, this should definitely be
considered a breaking change.
