Interactive Markdown editor with real-time split-screen preview. Write notes, documentation, project summaries, and export directly as clean PDF documents or web-ready HTML.
Verify file integrity and authenticity before uploading to government portals. Calculates SHA-256, SHA-1, and MD5 cryptographic checksums of any document, certificate, or image file in milliseconds using browser WebCrypto.
Government portals, tender submissions, and university verification systems use SHA-256 hashes to guarantee that a document has not been tampered with or corrupted during upload.
No. It calculates cryptographic hashes (SHA-256, SHA-1, MD5) entirely inside your web browser using the native Web Crypto API.
