About This Tool
We built this free online tool to make it simple for anyone toencrypt a message before sharing it, without needing to install software or create an account. Whether you want to protect a private note, secure sensitive information, or learnhow to encrypt email content before sending it, this tool handles it in seconds.
Why We Built This
Plain text messages sent over email, chat, or messaging apps can be read by anyone who intercepts them. We wanted a straightforward way to encrypt message content using strong, industry-standard encryption — without the complexity of dedicated encryption software or the risk of sending your data to a third-party server.
How It Works
Every message you encrypt is protected usingAES-256 encryption combined with PBKDF2 key derivation — the same category of cryptography trusted by banks and secure messaging platforms. All encryption and decryption happens locally in your browser using the Web Crypto API. Your message and password are never transmitted to, or stored on, any server.
Our Commitment to Privacy
This tool is 100% free, requires no sign-up, and collects no personal data. We believe strong encryption should be accessible to everyone, not just those with technical expertise or paid software.
