Why Privacy Tools Matter More Than Ever
Every day, sensitive information is shared carelessly — in emails, in documents sent to vendors, in code committed to repositories, in CSV exports forwarded through WhatsApp. A single exposed API key can drain a cloud account. A CNIC number in an unredacted document can enable identity fraud. Rafiqy's privacy and security tools give you the ability to encrypt, detect exposure, and redact sensitive data before it causes damage — all running locally in your browser, with nothing sent to any server.
Key Features at a Glance
- Text Encryptor — AES-256 encryption and decryption, password-protected, works fully offline, copy encrypted text to share safely
- Data Leak Detector — paste any text or code, automatically detect exposed emails, phone numbers, IP addresses, API keys, passwords, and credit card patterns
- Smart Document Redaction — upload a PDF or paste text, auto-detect PII (names, CNICs, phone numbers, emails), redact with black bars or replace with placeholders, export redacted PDF
1. Text Encryptor
When you need to send a password, a secret note, or confidential information through an insecure channel — a chat app, an email, a shared document — encrypting it first ensures that only the intended recipient can read it. Rafiqy's Text Encryptor uses AES-256, the same encryption standard used by governments and banks worldwide, to convert your plaintext into unreadable ciphertext locked by a password you choose.
The tool works entirely offline — encryption happens in your browser using the Web Crypto API, so the original text and the password never leave your device. The encrypted output is a compact string you can paste anywhere. The recipient uses the same tool with the same password to decrypt. No accounts, no keys to manage, no server-side storage. Just pure, strong encryption available instantly.
2. Data Leak Detector
Before publishing a blog post, committing code, sharing a spreadsheet, or sending a document externally, it is worth checking whether any sensitive data is accidentally included. The Data Leak Detector lets you paste any text — a code file, an email draft, a CSV export, a log file — and automatically scans it for patterns that indicate sensitive data exposure.
The detector identifies: email addresses, phone numbers (including Pakistani formats), IP addresses, API keys and tokens (common patterns like AWS, Google, Stripe, OpenAI), password-like strings in configuration files, and credit card number patterns. Each match is highlighted in the text and counted in a summary report, giving you a clear picture of what needs to be removed or replaced before sharing.
3. Smart Document Redaction
Legal firms, HR departments, healthcare providers, and government offices regularly need to share documents with sensitive information removed. Doing this manually — drawing black boxes in a PDF editor, hoping you caught everything — is slow and error-prone. The Smart Document Redaction tool automates the detection and removal of personally identifiable information.
Upload a PDF or paste text, and the tool automatically detects PII patterns: full names (using NLP heuristics), CNIC numbers (13-digit Pakistani format), phone numbers, email addresses, and other sensitive patterns. You can choose to redact with black bars (standard legal redaction) or replace with fake-but-plausible placeholders (useful for test data generation). The output is an exported redacted PDF or text that is safe to share, with all detected PII removed or masked.
The Offline-First Principle
The most important aspect of all three tools is that they process data locally in your browser. There is no upload to a cloud service, no logging of your input, no analytics on your content. For genuinely sensitive documents — legal files, medical records, financial data — this is not just a convenience: it is a requirement. Rafiqy's security tools are built on this offline-first principle, so you can use them even for your most confidential information.
When to Use Each Tool
Use the Text Encryptor whenever you need to share a secret over an insecure channel. Use the Data Leak Detector as a pre-flight check before any document leaves your hands. Use the Document Redaction tool when sharing documents that contain other people's information. Together, they cover the full privacy lifecycle: protect, detect, and redact.
