FAQs About the AES Cipher Tool
❓ Is AES encryption secure?
Yes! AES is an industry-standard encryption method used by governments, financial institutions, and enterprises worldwide. The 256-bit key version is virtually unbreakable.
❓ Can I reuse saved encryption keys?
Absolutely! You can store and reuse keys for convenience. However, ensure keys are kept confidential and secure to prevent unauthorized access.
❓ What happens if I lose the decryption key?
Without the correct key, decryption is impossible. Always back up your encryption keys securely.
❓ Why should I use PKCS7 Padding?
PKCS7 Padding ensures data aligns correctly with AES block sizes, preventing errors during encryption or decryption.
❓ Can I encrypt and decrypt files, not just text?
Yes! The tool supports file encryption and decryption, allowing you to secure documents, images, and other files.
