const rawInput = "PROVIDER_SECRET_KEY_PATTERN";

const scrubbed = redactSecrets(rawInput);

==> Output: "[REDACTED_KEY_TOKEN]" (Safe for Contextual Review)

Learn how automated AST pattern matching, regular expression scanners, and zero-trust redaction catch hardcoded API keys before they leak.
## Why Hardcoded Secrets are the #1 Cloud Security Vector In modern cloud applications, API keys, database connection strings, and webhook secrets serve as master credentials. Unlike traditional user passwords, API tokens often carry broad administrative privileges to create compute instances, read databases, or charge financial cards. When working with AI coding assistants, developers frequently paste API keys into code for quick testing and forget to replace them before committing to Git. --- ## Common Signature Patterns of Modern Cloud Providers Automated secret detection engines rely on high-entropy string heuristics and provider-specific prefix signatures: - **OpenAI Secret Keys:** `sk-...` or `sk-proj-...` (20–80 alphanumeric characters) - **Anthropic Claude Keys:** `sk-ant-api03-...` (80–120 characters) - **Google / Gemini API Keys:** `AIzaSy...` (39 characters) - **Stripe Secret Keys:** `sk_live_...` or `rk_live_...` - **Stripe Webhook Secrets:** `whsec_...` - **AWS Access Keys:** `AKIA...` or `ASIA...` (20 characters) - **GitHub Personal Access Tokens:** `ghp_...` or `github_pat_...` - **Database URIs:** `protocol://username:password@hostname:port/dbname` --- ## How CoreVibbe Implements Zero-Trust Redaction When you upload a project ZIP to CoreVibbe, our in-memory parser sanitizes the codebase before any analysis occurs: 1. **In-Memory Stream Parsing:** Unpacks the archive directly in RAM without saving unencrypted files to persistent disk. 2. **Deterministic Pattern Scrubbing:** Matches provider signatures and replaces secret values with redaction tokens like `[REDACTED_OPENAI_KEY]`. 3. **Safe Contextual Review:** Only sanitized structural metadata is reviewed by AI models, ensuring your private infrastructure credentials never leave your control.
Zero-Trust Scanner

Check your codebase for exposed keys

Run our in-memory scanner to detect OpenAI, Stripe, AWS, and database credentials before publishing.

Scan for Secrets

Practical Implementation Checklist

1. Run Git Secret Scanners in Pre-Commit Hooks

Set up tools like truffleHog or git-secrets to block commits containing private key patterns.

2. Scan for Database Connection Strings

Verify that postgresql:// or mongodb:// connection URIs with embedded passwords are not stored in source files.

3. Rotate Compromised Keys Immediately

If an API key is ever committed to public git history, treat it as immediately compromised and rotate it in your provider dashboard.
