FAQs
What is an Encrypt & Decrypt tool?
It’s an online utility that lets you convert plaintext into encrypted text and decrypt cipher text back to readable form using secure algorithms.
Which algorithms does this tool support?
The tool supports multiple modern encryption algorithms, including AES-256-CBC, which is widely trusted for strong data security.
Is AES-256-CBC secure?
Yes. AES-256-CBC is considered very secure and is used in banking, government, and enterprise-level applications.
Do I need a secret key?
Yes. Encryption and decryption both require the same secret key. Without the correct key, the text cannot be decrypted.
Does the tool store my data?
No. All encryption and decryption happen instantly in your browser. Nothing is stored, logged, or shared.
Can I decrypt text encrypted elsewhere?
Yes, as long as you use the same algorithm, mode, and secret key.
