Secure Text Encryption – simple & reliable
This page and app allow you to encrypt and decrypt text directly in your browser or on your device – no server, no tracking, completely local. You enter a text, we generate a random key, and encrypt it using the modern AES-GCM algorithm.
🧠
What is AES-GCM?
AES-GCM stands for Advanced Encryption Standard – Galois/Counter Mode. It is a highly secure method that not only encrypts the content but also protects its integrity. This means: any manipulation of the encrypted text is detected and blocked.
🔑
Why a random key?
Instead of using a password, we generate a new cryptographically secure key for every operation. This makes each encrypted text unique and impossible to trace. The key is provided to you as a link or file – only those who possess it can decrypt the text.

Security at a glance
• AES-GCM with 256 bits: Industry standard, used by governments and banks
• Random key per message: No reuse, no patterns
• Local in browser/app: No data transmission, no storage
• Authenticated encryption: Protection against manipulation and replay attacks
