=head1 NAME
Crypt::Bear::EC::PublicKey - An EC public key in BearSSL
=head1 VERSION
version 0.002
=head1 SYNOPSIS
 if ($public_key->ecdsa_verify('sha256', $hash, $signature)) {
     say "Success!";
 }
 my $shared = $private_key->ecdh_key_exchange($public_key);
=head1 DESCRIPTION
This represents a elliptic curve public key. The curve type can be one of the following:
=over 4

=item * C<'sect163r1'>
=item * C<'sect163r2'>
=item * C<'sect193r1'>
=item * C<'sect193r2'>
=item * C<'sect233k1'>
=item * C<'sect233r1'>
=item * C<'sect239k1'>
=item * C<'sect283k1'>
=item * C<'sect283r1'>
=item * C<'sect409k1'>
=item * C<'sect409r1'>
=item * C<'sect571k1'>
=item * C<'sect571r1'>
=item * C<'secp160k1'>
=item * C<'secp160r1'>
=item * C<'secp160r2'>
=item * C<'secp192k1'>
=item * C<'secp192r1'>
=item * C<'secp224k1'>
=item * C<'secp224r1'>
=item * C<'secp256k1'>
=item * C<'secp256r1'>
=item * C<'secp384r1'>
=item * C<'secp521r1'>
=item * C<'brainpoolP256r1'>
=item * C<'brainpoolP384r1'>
=item * C<'brainpoolP512r1'>
=item * C<'curve25519'>
=item * C<'curve448'>
=back
Common values include C<'curve25519'>, C<'curve448'>, C<'secp256r1'>, C<'secp384r1'>, C<'secp521r1'>.
=head1 METHODS
=head2 new($curve, $point)
This returns a new public key representing the given C<$point> on C<$curve>.
=head2 ecdsa_verify($hash_type, $hash_value, $signature)
This verifies a C<$signature> as returned by C<ecdsa_sign>. The C<$hash_value> must be the hash you computer yourself over the data.
=head2 curve()
This returns the curve of this public key.
