How to Use: File Encryptor

What is the File Encryptor & Decryptor?

This is a security tool that allows users to encrypt (lock) and decrypt (unlock) files using a password. It employs the strong AES-256 encryption standard to secure the file's contents, making them unreadable without the correct password. All operations are performed securely within the user's browser, meaning files are never uploaded to a server.

History of this Feature

File encryption has traditionally been the domain of specialized software that required installation and technical knowledge. With growing concerns about online privacy, the need for a simple, accessible encryption tool became apparent. Our File Encryptor & Decryptor was designed to fill this need, providing military-grade encryption in a user-friendly web interface. By performing all operations client-side, it offers a high level of security and privacy, as the user's files and password never leave their computer.

Who Commonly Uses This Feature?

This tool is used by anyone who needs to securely store or transmit sensitive information. This includes professionals handling confidential documents, journalists protecting sources, and individuals who want to password-protect personal files like financial records or private journals before storing them on the cloud or a shared device.
