Stop Leaking AWS Keys to Claude: A Developer's Guide

Developers are the Biggest Security Risk

We all love Claude 3.7 Sonnet. It is currently the undisputed king of coding.

But how often do you paste a config file that contains:

AWS_ACCESS_KEY_ID=AKIA...?

Every time you do that, you leak production credentials.

The Scale of the Problem

Fact: 45% of developers admit to pasting sensitive work data into GenAI tools.

GitHub reports that millions of secrets are leaked to public repositories every year. Now imagine how many are leaked to AI providers that retain conversation history.

The "Secret Scanner"

SafePipe isn't just for PII. It's for Secrets.

We scan every prompt for:

• AWS Keys: Access Key IDs and Secret Access Keys
• Stripe Secrets: Live and test API keys
• Private SSH Keys: RSA, ED25519, and ECDSA keys
• Database Strings: PostgreSQL, MongoDB, MySQL connection URIs
• API Tokens: GitHub, Slack, Discord, OpenAI keys
• Private Keys: PEM certificates and JWTs

How It Works

// Developer accidentally pastes .env contents
const response = await safepipe.chat({
  model: "claude-3-7-sonnet-20250219",
  messages: [{
    role: "user",
    content: `Help me debug this:
    DATABASE_URL=postgres://admin:secretpass123@prod.db.com:5432/users
    STRIPE_SECRET_KEY=sk_live_abc123...
    AWS_SECRET_ACCESS_KEY=wJalrXUtnFEMI...`
  }]
});

// What Claude actually receives:
// DATABASE_URL=[DATABASE_URL_REDACTED]
// STRIPE_SECRET_KEY=[STRIPE_KEY_REDACTED]
// AWS_SECRET_ACCESS_KEY=[AWS_SECRET_REDACTED]

Block vs. Redact Modes

SafePipe gives you two options:

1. 1 Redact Mode: Replace secrets with placeholders. The AI can still help with the logic.
2. 2 Block Mode: Kill the request entirely. Return an error asking the developer to remove secrets.

For production environments, we recommend Block Mode with Slack notifications to your security team.

Integration with Claude 3.7 Sonnet

Claude 3.7 Sonnet is the best coding assistant with its hybrid reasoning capabilities, but it's also the most likely to receive sensitive code. Here's how to use it safely:

import Anthropic from "@anthropic-ai/sdk";

const anthropic = new Anthropic({
  baseURL: "https://api.safepipe.eu/v1/anthropic",
  apiKey: "sp_live_..."
});

// Now all Claude requests go through SafePipe
// Secrets are automatically redacted

The DeepSeek Alternative

For non-sensitive coding tasks, consider DeepSeek-V3 or DeepSeek Coder:

• 10x cheaper than Claude
• Comparable coding performance
• Still protected by SafePipe's secret scanner

Protect your repo from your own team.
