Crypt::Perl::X509::Extension::acmeValidation_v1
See Crypt::Perl::X509v3 for a more useful syntax for instantiating this extension as part of certificate creation. The following is how to instantiate it directly .. which isn’t very useful per se.
my $extn = Crypt::Perl::X509::Extension::acmeValidation_v1->new( $string_of_32_octets, );
This is the X.509 extension to use when creating validation certificates for use with the experimental ACME TLS ALPN challenge, described at https://datatracker.ietf.org/doc/draft-ietf-acme-tls-alpn/.
