Flezen Cloud Architecture Overview
Flezen's infrastructure is built upon distributed object storage designed to store massive video archives efficiently. When a creator uploads a file, it is ingested into storage clusters, indexed with unique cryptographic identifiers, and distributed across global content delivery networks.
Understanding how these links operate allows developers and enthusiasts to extract maximum performance and reliability from the ecosystem.
Dissecting the Flezen Share URL
A typical Flezen share link looks like:
https://flezen.com/s/1a2b3c4d5e6f7g8h9i0jklmnopqrstuv
Key components of this structure:
- Host Domain: `flezen.com` indicates the public sharing gateway.
- Route Key: `/s/` designates a public or unlisted share resource.
- Resource Hash: `1a2b3c4d5e6f7g8h9i0jklmnopqrstuv` is a unique Base32/Base36 encoded identifier corresponding to the underlying media object in the metadata index.
When queried via an extraction API, this hash resolves to a direct CDN location such as:
https://dl.fzcdn.cloud/cf/313232393935/1a2b3c4d5e6f7g8h9i0j_...bin
API Authentication & HMAC-SHA256 Signatures
Enterprise extraction services, such as the TeraBox/Flezen developer API, protect their extraction endpoints using HMAC-SHA256 request signing.
The authentication workflow functions as follows:
- Timestamp Generation: Capture current Unix epoch in seconds (e.g. `1758921600`).
- Payload Construction: Concatenate HTTP method, path, timestamp, and request body:
```
POST/api/v1/flezen/extract1758921600{"url":"https://flezen.com/s/..."}
```
- Cryptographic Signing: Generate a keyed-hash message authentication code using your private API Secret:
```typescript
const signature = crypto.createHmac('sha256', secret)
.update(payload)
.digest('hex');
```
- Header Injection: Pass `X-API-Key`, `X-Timestamp`, and `X-Signature` headers with every POST request.
This prevents man-in-the-middle tampering, replay attacks, and unauthorized consumption of developer quotas.
Edge Caching & Cloudflare CDN Distribution
Direct links are served via Cloudflare CDN (dl.fzcdn.cloud). Features include:
- Byte Range Requests: Allows users to seek to minute 45:00 instantly without downloading the preceding 44 minutes.
- Edge Hit Caching: Popular files are cached at regional internet exchange points, ensuring instant time-to-first-byte (TTFB < 50ms).
