I vaguely remember that change. According to the change in https://github.com/weidai11/cryptopp/commit/9b174e84de7a, you should be able to: AccessMaterial().Load(bt) or AccessMaterial().Save(bt) In you case, use the Encryptor object: Encryptor.AccessMaterial().Save(pub); Jeff -- You received this message because you are subscribed to "Crypto++ Users".
