# Example 04: Identity Verification with Safety Numbers
|
||
|
|
|
||
|
|
Shows how two parties can compare safety numbers (60-digit fingerprints) out-of-band to detect a man-in-the-middle attack at session establishment.
|
||
|
|
|
||
|
|
## Run
|
||
|
|
|
||
|
|
```bash
|
||
|
|
bun run main.ts
|
||
|
|
```
|
||
|
|
|
||
|
|
## What it shows
|
||
|
|
|
||
|
|
- Generating identity fingerprints
|
||
|
|
- The "safety number" format (12 groups of 5 digits)
|
||
|
|
- Comparing fingerprints to verify a peer's identity
|
||
|
|
- What it looks like when a MITM is attempted (different fingerprint)
|
||
|
|
- `acceptIdentityChange()` for handling legitimate identity rotation
