Keystore Vision Community Card Encryption Distribution System 5.0.9

Keystore is an authorization and issuance solution based on Invision Community 5 (IPS 5), covering a complete loop of "product management → card password issuance → authorization verification → order tracking". It will deeply integrate verification services with backend management, providing a plug and play commercial infrastructure.

-Composition

• -Verification server: The built-in interface is responsible for authorizing decryption and integrity verification, time window verification, device/domain binding, and certificate signing.

• -Client verification: The distribution has a built-in reinforcement verification process (HTTPS enforcement, domain whitelist, fixed UA, Base64URL packaging).

• -Backend management: issuing products (without price fields), card vault, order flow and log auditing, focusing on issuing cards and authorization itself.

-Workflow

1) Create the issued product and configure the card password → 2) Deliver the card password to the end user → 3) Initiate encryption verification on the client side

→ 4) The server returns the authorization result and constraints (including signature/certificate) → 5) The backend can view the real-time order and authorization status.

##Key characteristics

• -Secure Communication: AES-256-CBC Encryption+Base64URL Packaging+HMAC Integrity Verification

• -Anti tampering: Fixed HTTPS authentication domain whitelist, built-in UA, disable plaintext rollback

• -Authorization constraint: Supports domain/device binding and fingerprint verification to prevent dissemination and abuse

• -Flexible card issuance: batch import/generation of card codes, inventory visibility and status management

• -Order Tracking: Order List, Status Flow, and Audit Information

• -Lightweight backend: integrated management of issued products, card codes, and orders (no product price field, more suitable for external store settlement)

• -Compatibility: Compatible with IPS 5.0. x, following framework specifications, easy to switch on and off

##Applicable scenarios

• -Forum/Community Business Plugin and Theme Distribution

• -Theme and feature extensions for IPS 5, authorized by domain/site; Can limit the installation of terminals and the number of migrations.

• -SaaS/Local Hybrid Authorization

• -Online strong verification+short-term offline grace period; The combination of instance fingerprint, replay protection, and time window enhances reliability and anti abuse capabilities.

• -Internal distribution and compliance audit of enterprises

• -Unified issuance of cards for multiple sites/departments, binding domain names/devices, authorization can be migrated and revoked, and audit trails can be retained.

• -Channel distribution and bulk issuance of cards

• -Batch generation/import of card codes, channel identification and inventory/status management, supporting large-scale distribution and recycling.

• -Regular trial and upgrade release

• -Time limit card encryption, grayscale release, version upgrade pass; Automatically expires upon expiration, supports renewal/regularization.

• -Connect with external stores/payment platforms

• -Price and settlement are handled externally (such as Paddle/Stripe/domestic card issuing platforms, etc.), while Keystore focuses on authorization verification and card issuance closed-loop.

• -Risk control and after-sales service

• -Abnormal domain name/multiple migration warning; Blacklist/Revocation of Authorization; Orders, devices, and binding changes can be tracked throughout the entire chain.

##Why choose Keystore

• -Stronger security baseline: time window verification, server authentication token (serverless), whitelist domain name

• -Less configuration: Verify that the server address is built-in and reinforced, no need for users to configure it themselves

• -Update process: Hand over the "price/amount" to an external store, with the backend only focusing on card issuance and authorization

##Safety Design Description (Brief)

• -Encryption: AES-256-CBC, request/response symmetric encryption

• -Packaging: timestamp+nonce+ciphertext → Base64URL, resistant to middleware rewriting

• -Integrity: HMAC-SHA256 signature (including hour/date factor)+daily authentication with server _cert

• -Transmission: Enforce HTTPS, fix domain whitelist, reject plaintext and untrusted addresses

##Installation and Getting Started (IPS 5)

• 1. Upload and install Keystore application in ACP application management

• 2. Open "Card Issued Products", "Card Password Management", and "Order Management" for basic configuration

• 3. Connect the client (plugin that requires authorization verification) to the authorization verification interface (encapsulated inside the plugin)

• 4. Import the card password and start selling it

Tip: The backend does not involve setting product prices; Please maintain the price in the external store/payment system.

##Frequently Asked Questions (FAQ)

-Q: Does it support offline?

A: Reasonable time windows and caching strategies can be configured to reduce the impact of short-term network fluctuations.

-Q: Can I customize the verification server?

A: Customization has been disabled for security and consistency, with built-in official verification address and reinforcement.

-Q: How to conduct secondary development?

A: Following the IPS application structure, the controller/model is clear and can be expanded as needed.
