The bypasses a few more defensive copies in
PublicKey.AsnEncodedData(AsnEncodedData)makes a defensive copy of the data for itself, which the constructor ofPublicKeyuses. However, there are a few factory methods inPublicKeythat create anAsnEncodedDatasolely for the purpose of transferring toPublicKey. In that circumstance, we can bypass the copy since the creation of theAsnEncodedDataalready made the defensive copy.Likewise for
X509Certificate2.PublicKey. This shaves several hundred bytes in allocation, scaling with the key size.
