Frequently Asked Questions

What encryption algorithms are supported?
The tool supports AES (Advanced Encryption Standard) in GCM, CBC, and CTR modes, plus educational ciphers like Simple XOR and Caesar cipher. AES is industry-standard and recommended for real security needs.
How secure is the encryption?
AES encryption is military-grade and used worldwide for sensitive data. However, this tool is for educational purposes - for production use, implement proper key management and use dedicated cryptographic libraries.
Can I use my own encryption key?
Yes! You can provide your own key or let the tool generate a cryptographically secure random key. Generated keys are displayed for your use but not stored anywhere.
What happens to my data and keys?
All encryption and decryption happens locally in your browser. No data, keys, or encrypted content is sent to any server or stored anywhere.
Why might decryption fail?
Common causes include wrong decryption key, mismatched algorithm, corrupted encrypted data, or incorrect output format. Ensure all parameters match those used for encryption.
