Replit Security Basics
Overview
Security best practices for Replit API keys, tokens, and access control.
Prerequisites
- Replit SDK installed
- Understanding of environment variables
- Access to Replit dashboard
Instructions
Step 1: Configure Environment Variables
# .env (NEVER commit to git)
REPLIT_API_KEY=sk_live_***
REPLIT_SECRET=***
# .gitignore
.env
.env.local
.env.*.local
Step 2: Implement Secret Rotation
# 1. Generate new key in Replit dashboard
# 2. Update environment variable
export REPLIT_API_KEY="new_key_here"
# 3. Verify new key works
curl -H "Authorization: Bearer ${REPLIT_API_KEY}" \
https://api.replit.com/health
# 4. Revoke old key in dashboard
Step 3: Apply Least Privilege
| Environment |
Recommended Scopes |
| Development |
read:* |
| Staging |
read:*, write:limited |
| Production |
Only required scopes |
Output
- Secure API key storage
- Environment-specific access controls
- Audit logging enabled
Error Handling
| Security Issue |
Detection |
Mitigation |
| Exposed API key |
Git scanning |
Rotate immediately |
| Excessive scopes |
Audit logs |
Reduce permissions |
| Missing rotation |
Key age check |
Schedule rotation |
Examples
Service Account Pattern
const clients = {
reader: new ReplitClient({
apiKey: process.env.REPLIT_READ_KEY,
}),
writer: new ReplitClient({
apiKey: process.env.REPLIT_WRITE_KEY,
}),
};
Webhook Signature Verification
import crypto from 'crypto';
function verifyWebhookSignature(
payload: string, signature: string, secret: string
): boolean {
const expected = crypto.createHmac('sha256', secret).update(payload).digest('hex');
return crypto.timingSafeEqual(Buffer.from(signature), Buffer.from(expected));
}
Security Checklist
- [ ] API keys in environment variables
- [ ]
.env files in .gitignore
- [ ] Different keys for dev/staging/prod
- [ ] Minimal scopes per environment
- [ ] Webhook signatures validated
- [ ] Audit logging enabled
Audit Logging
interface AuditEntry {
timestamp: Date;
action: string;
userId: string;
resource: string;
result: 'success' | 'failure';
metadata?: Record<string, any>;
}
async function auditLog(entry: Omit<AuditEntry, 'timestamp'>): Promise<void> {
const log: AuditEntry = { ...entry, timestamp: new Date() };
// Log to Replit analytics
await replitClient.track('audit', log);
// Also log locally for compliance
console.log('[AUDIT]', JSON.stringify(log));
}
// Usage
await auditLog({
action: 'replit.api.call',
userId: currentUser.id,
resource: '/v1/resource',
result: 'success',
});
