Free Text Encryption Tool — Encrypt Anything in Your Browser
Why Browser-Based Encryption Matters
When text is private, the safest workflow is to keep it in the browser and avoid uploading it somewhere unnecessary. Browser-based encryption gives you a simple way to protect notes, secrets, and messages before they ever leave your device.
How AES-256-GCM Protects Your Text
AES-256-GCM is a modern encryption standard that protects both confidentiality and integrity. FreePassGen uses a password-derived key and a unique salt and IV so the same text does not produce the same output twice. That makes the encrypted result harder to analyze and safer to share.
Good Things to Encrypt This Way
This workflow is ideal for private notes, recovery codes, API snippets, customer details, and other text you do not want to leave exposed in plain form. It is also useful when you need to send a secure message through a normal channel like email or chat.
How to Share It Safely
Encrypt the text first, then send the encrypted output through the channel you already use. Share the password separately. That way, if the message is intercepted, the content still remains unreadable without the password.
How to Decrypt Without Making Mistakes
To decrypt safely, paste the full encrypted block, enter the exact password, and verify the output before copying it elsewhere. A missing character or wrong password means the text will not come back correctly, so it is worth checking both carefully.
