О пакете: Perl extension for OpenSSL EC (Elliptic Curves) library
Описание:

This module provides a standard (non-OO) interface to the OpenSSL EC (Elliptic Curve) library.
Some OO Calls are supported.

Most of the functions described in openssl/ec.h are supported.

It provides the Crypt::OpenSSL::EC class which defines some high level functions and constants.
At also provides 4 other classes for managing EC objects:

=over 4

=item Crypt::OpenSSL::EC::EC_GROUP

=item Crypt::OpenSSL::EC::EC_POINT

=item Crypt::OpenSSL::EC::EC_KEY

=item Crypt::OpenSSL::EC::EC_METHOD

=back

All objects created by these 4 classes are implemented as blessed Perl mortal
references.  This ensures they will be auto-destroyed when the Perl variable
becomes unreferenced. ASlo the approproae EC free function wil be called to
free the underlying EC object.

Further, it means that many of the functions below can be called using O-O
methods.  If a method's first argument is the same as the class the method is
in, then it can be called O-O style. For example the following 2 calls are
equivalent:

=over 4

=item my $newgroup = Crypt::OpenSSL::EC::EC_GROUP::dup($group);

=item my $newgroup = $group->dup();
