Various enhancements
Created by: juaristi
I find myself in the need of these functions for HPKP, but since they're pretty generic, I put them here, in a separate patch.
-
wget_base64_get_decoded_length
is a macro that computes the length a base64-decoded string will have after decoding. It basically translates to((len + 3) / 4) * 3 + 1
, but you don't have to remember it :) - Two new functions:
wget_iri_is_ipv4_address
andwget_iri_is_ipv6_address
, that test whether the host part of an IRI is a literal IPv4/IPv6 address or not. These depend oninet_pton
, which fortunately is part of gnulib. Actually, I notice the gnulib code is copied verbatim into the equivalent wget function, I don't know why. - HSTS should not add a host if it's a literal IPv4 or IPv6 address. This is mandated by the spec. The same goes for HPKP as well. And that's why the two functions above come in handy.
