What is AES Encryption?
AES is a symmetric encryption algorithm: the same secret is used to encrypt and decrypt. Keyra preserves its existing CryptoJS passphrase format for compatibility and runs entirely in your browser.
Key Features
Compatibility-first format
Decrypt values created by the existing Keyra CryptoJS implementation.
JSON Support
Optimized to easily encrypt and decrypt JSON data structures while maintaining validity.
Client-Side Processing
All operations happen in your browser. Your data never leaves your device.
Free and accountless
Use the tool without registration, subscription, or personal information.
How to Use
Enter Your Data
Paste your JSON data or any text you want to encrypt in the input field. The tool will automatically format JSON for better readability.
Set Encryption Key
Enter a secure encryption key. Important: You must remember this key to decrypt your data later. We cannot recover it for you.
Encrypt or Decrypt
Click the Encrypt button to generate your secure data. To reverse the process, paste the encrypted text, enter the same key, and click Decrypt.
Security Best Practices
- Use a strong, unique encryption key (at least 16 characters recommended)
- Never share your encryption key publicly or over insecure channels
- Store your encryption keys securely (e.g., in a password manager)
- Rotate your keys periodically for sensitive data
Frequently Asked Questions
Where is my data processed?
Processing happens in the current browser tab. The app has no API or analytics, but you remain responsible for device security and key handling.
What if I forget my encryption key?
Unfortunately, if you lose your encryption key, there is no way to recover the encrypted data. AES is designed to be secure, meaning without the key, the data is inaccessible.
Can I use this for commercial projects?
Yes! This tool is free to use for both personal and commercial projects.
