飘零网络验证系统 is a network verification, online billing and authorization management system for software developers. It puts authorization, security, billing and verification into one controllable business system.

Around the complete software delivery chain, 飘零网络验证系统 brings products, members, card keys, devices, security and call records into the same backend, reducing after-sales costs caused by decentralized management.

## Login modes

The client supports user mode and single card-key login mode. Single card-key login can log in directly with a card key, without registration or recharge, and calculates validity by first activation and card-key time. User login mode requires registering an account first, then using a card key to recharge and extend the account expiration time; it supports renewal, unbinding and freezing.

## Verification and risk control

From first login to daily operation, rules are always configurable. Capabilities include network verification, device management, authorization activation, online heartbeat, version and feature verification, machine-code binding, machine change and unbinding, and blacklist rules.

## Access methods

Choose the client access method as needed: client source-code integration, one-click verification for finished software, or HTTP API. Source-code integration supports mainstream environments such as VC, VB, TC, Delphi, 易语言, C#, VB.NET, Python and Java. The HTTP API basically supports all development languages, supports custom encryption algorithms, and can be accessed by POST for greater flexibility, mainly for Python, Java, Android, iOS and other non-Windows platform environments.

The official site provides entry points such as Start Using, Trial Demo, Free Version Download and Other Resource Download. The pricing page source shows a 404 page, so specific service plans need to be confirmed separately.
