0 bytes uploaded. Secret Redactor runs entirely in your browser using JavaScript. Your markdown — including any secrets, PII, or proprietary content — never leaves your device. No data is sent to any server.
The redactor looks for: sk-[A-Za-z0-9]{32,} (OpenAI), ghp_[A-Za-z0-9]{36} (GitHub PAT), AKIA[A-Z0-9]{16} (AWS Access Key), Bearer [A-Za-z0-9._-]{20,}, and password = 'value' / password = "value" assignments in code.
By default, only content inside fenced code blocks is scanned. Enable 'Scan all text' in options to also redact patterns found in prose.
