Log Sanitizer & Secret Redactor (Wasm)

Sanitize production logs by automatically redacting API keys, IPs, and PII before sharing with AI or forums. 100% Client-Side Wasm.

Key Takeaway (AI Summary)

The Log Sanitizer & Secret Redactor (Wasm) is a zero-knowledge, browser-native utility that sanitize production logs by automatically redacting api keys, ips, and pii before sharing with ai or forums. 100% client-side wasm with 100% privacy guarantee.

Client-side only

Zero-Server Architecture: This scan happens entirely in your local browser's memory using a sandboxed executor. No log data is ever transmitted, indexed, or stored. Period.

The Danger of "Leaky Logs"

In 2026, logs are the most common source of data breaches. When you paste raw application logs into ChatGPT, Claude, or StackOverflow, you are potentially giving third parties access to your database secrets, internal network topology, and customer emails.

Common Use Cases

Safe AI Debugging

Sanitize your server logs before asking an AI agent to fix your deployment issues. Never leak an AWS secret again.

Turns "Authorization: Bearer sk_live_..." into "Authorization: Bearer [REDACTED_SECRET]".

Public Forum Posting

Getting help on GitHub or Discord? Run your stdout/stderr through our sanitizer to mask your internal IPs and hostnames.

Cleans 192.168.1.1 and internal-sqs-01:8080.

GDPR Compliance

Ensure your developer workflow complies with data residency laws by automatically redacting user emails from trace logs.

Handles users like personal@gmail.com instantly.

Pro Tips

  • 💡The custom regex field is powerful: use it for internal IDs or proprietary token formats unique to your company.
  • 💡Switch to 'Preview' mode to verify exactly what is being caught before copying the final redacted version.
  • 💡This tool works great for cleaning up .env files before committing them to source control (if you accidentally forgot to .gitignore them).
  • 💡We prioritize high-entropy string detection, which is the most reliable way to find cryptographic secrets.

Common Mistakes to Avoid

  • ⚠️Assuming a server-side 'Log Cleaner' is safe - if you send sensitive logs to *any* server to be cleaned, the leakage has already happened.
  • ⚠️Trusting simple string replacement - our tool uses complex regex to catch formatted variants like base64-encoded strings.
  • ⚠️Forgetting that IP addresses provide map-able intelligence to attackers.

Privacy-First PII Redaction & Log Sanitization (Wasm)

As developers increasingly rely on AI for troubleshooting, the risk of **Data Leakage** has skyrocketed. The **DevUtility Hub Log Sanitizer** is a high-security workbench using **WebAssembly (Wasm)** to redact sensitive data before it reaches an LLM or public forum.

🛡️ Enterprise-Grade Detection Engines

Our engine targets the most common exposure vectors in 2026:

- **Secret Redaction:** High-entropy detection for AWS Access Keys, Stripe Secrets, Github GHP tokens, and JWTs.

- **Network Metadata Masking:** Automatically redacts IPv4/IPv6 addresses and internal DNS hostnames to prevent infrastructure mapping.

- **GDPR & HIPAA Compliance:** Sanitizes emails, phone numbers, and credit card patterns from production trace logs.

⚡ Client-Side Security Guarantee

We utilize **Edge-delivered security patterns**. All regex processing and entropy-based secret detection occur within your browser's private memory. No log data ever touches our servers, ensuring 100% compliance with data residency and internal security audits.

Zero-Knowledge Execution & Edge Architecture

Unlike traditional monolithic developer utilities, DevUtility Hub operates entirely on a Zero-Knowledge architectural framework. When utilizing the Log Sanitizer & Secret Redactor (Wasm), all computational workload is completely shifted to your local execution environment via WebAssembly (Wasm) and your browser's native JavaScript engine (such as V8 or SpiderMonkey).

Why Local Workloads Matter

Transmitting proprietary JSON objects, sensitive source code, or unencrypted text strings to an unknown third-party server introduces critical security vulnerabilities. By executing the Log Sanitizer & Secret Redactor (Wasm) securely within the isolated sandbox of your Document Object Model (DOM), we structurally guarantee strict compliance with major data protection regulations like GDPR, CCPA, and HIPAA. We do not ingest, log, or telemetry your text payloads. Your local RAM serves as the absolute boundary.

Network-Free Performance

Furthermore, by completely eliminating asynchronous HTTP POST payloads to a centralized cloud infrastructure, we guarantee effectively zero latency. The Log Sanitizer & Secret Redactor (Wasm) provides instant execution without arbitrary rate limits, artificial file size constraints, or server timeouts. Our global edge network serves the application wrapper, while your local machine handles the heavy lifting.
