FR-AI / ANALYSISWhy it is worth attention
Implements a defense-in-depth payment callback flow (RSASSA-PKCS1-v1_5 signing, RSA-OAEP/AES-256-GCM envelope decryption) and includes security regression tests plus GitHub Actions CI, all without Composer dependencies.
Who it is for
- WHMCS 9 merchants who want to accept cryptocurrency payments via HashPay
- WHMCS developers integrating or customizing HashPay gateway modules
- Operators or support staff managing HashPay payment infrastructure
- PHP developers seeking a secure payment callback implementation reference
Use cases
- Accepting HashPay cryptocurrency payments in WHMCS 9
- Automatically marking WHMCS invoices as paid after verified callbacks
- Safely handling duplicate notifications and repeated transactions
- Running security regression tests without requiring WHMCS commercial source code
Strengths
- Validates merchant, timestamp, status, amount, currency, and transaction uniqueness before marking invoices paid
- Uses RSA-OAEP SHA-256 and AES-256-GCM for callback decryption and authentication
- Provides idempotent handling for duplicate transactions and notifications
- Includes security regression tests and GitHub Actions CI on PHP 8.2 and 8.3
Considerations
- Requires WHMCS 9.x and PHP 8.2/8.3, plus cURL and OpenSSL extensions
- Third-party module, not an official WHMCS or HashPay component
- Callback requires a public HTTPS endpoint and the log directory must be writable by the web server
