Introducing HAR Sanitizer: secure HAR sharing

What this post added

Introduced HAR Sanitizer, an open-source tool built on Cloudflare Workers that sanitizes HTTP Archive (HAR) files by stripping session-related cookies and JWTs. This tool addresses the security risk of HAR files being used as an attack vector after the Okta breach. The sanitizer offers default stripping of sensitive information and a 'just enough' sanitization mode for specific use cases like Cloudflare Access JWTs, where the cryptographic signature is removed while retaining debugging information. Future enhancements include DLP scanning and automated sanitization in collaboration tools.
