Online Encryption: Protect Your Information with Military-Grade Algorithms
Data encryption is the most effective technique for protecting confidential information. Our online encryption tool implements military-grade algorithms like AES-256 and ChaCha20 directly in your browser, without sending data to external servers.
AES-256 (Advanced Encryption Standard) is the standard used by governments and military organizations worldwide. ChaCha20 is the modern alternative preferred by Google and used in TLS 1.3 for HTTPS connections.
The entire encryption and decryption process happens locally on your device using the browser's Web Crypto API, ensuring your sensitive data never leaves your equipment.
How does it work?
- 1Type or paste your message
Enter the text you want to encrypt in the input field.
- 2Set a password
Define a strong password that will be used as the encryption key.
- 3Select the algorithm
Choose between AES-256 (standard) or ChaCha20 (modern and fast).
- 4Encrypt or decrypt
Click encrypt to protect your message or decrypt to recover the original.
Frequently Asked Questions
Yes. We use the browser's native Web Crypto API which implements the same algorithms as desktop applications. Your data is never sent to any server.
AES-256 is the most widely adopted standard, optimized for hardware with AES-NI instructions. ChaCha20 is faster on devices without hardware acceleration (like mobiles) and is resistant to timing attacks.
No. Symmetric encryption requires the same password to encrypt and decrypt. If you lose the password, the data is unrecoverable. That's what makes encryption secure.
