This doc specs/tls/tls.md contains an outdated link in the following section.

Certificates MUST use the NamedCurve encoding for elliptic curve parameters. Endpoints MUST abort the connection attempt if is not used. Failure to enforce this restriction allows “Whose Curve Is It Anyway” attacks, which completely compromise the security of the connection. Similarly, hash functions with an output length less than 256 bits MUST NOT be used, due to the possibility of collision attacks. In particular, MD5 and SHA1 MUST NOT be used.

Does it needs to be updated with link from web archive or should be removed?
