NAME

       Authen::U2F::Tester::Keystore::Wrapped - Wrapped Keystore for Authen::U2F::Tester

VERSION

       version 0.03

SYNOPSIS

        my $key = Crypt::PK::ECC->new;
        ...
        my $keystore = Authen::U2F::Tester::Keystore->new(key => $key);

        my $keypair = Authen::U2F::Tester::Keypair->new;
        my $handle = $keystore->put($keypair->private_key);

        if ($keystore->exists($handle)) {
            my $pkec = $keystore->get($handle);
        }

DESCRIPTION

       This is a "wrapped" key store for Authen::U2F::Tester.  This is the default key store used
       by Authen::U2F::Tester.  This key store does not require any backing storage at all to
       keep track of registered keys.  Instead, it generates key handles by encrypting the
       private key using the tester's private key and returns this encrypted value as the key
       handle.  This is somewhat vaguely describe in the FIDO/U2F specifications as a "wrapped"
       key handle.  My experience is that most of the U2F devices out there use some variation of
       this scheme because it allows the devices to be used with an infinite number of services
       as no local storage is required on the U2F device.

       Storage of the key handle is not required because this class can tell if the handle is
       valid or not by trying to decrypt the passed in key handle.  If decryption succeeds, then
       the handle is valid.  Otherwise, the handle is not valid.
