The problem

In a 2023 Cyberhaven study of about 1.6 million workers, about 11% of what employees pasted into ChatGPT was confidential. PasteCloak covers one part of that: credentials.

What PasteCloak looks for

Plain-category detection for the secrets developers paste most — no vague "AI-powered" claims, just the patterns it actually looks for.

API Keys

OpenAI, Anthropic, AWS, GitHub, GitLab, and Stripe key formats.

Bearer Tokens & JWTs

Authorization: Bearer headers and JWTs, matched by their structure.

Passwords in Code

Hardcoded credentials in config files, .env dumps, and scripts.

DB Connection Strings

Postgres, MySQL, MongoDB, and Redis URIs with embedded credentials.

Private Keys

PEM and OpenSSH private key blocks.

Custom Rules

Define your own patterns for internal tokens or proprietary formats.
