AES Encryption & Decryption

AES (Advanced Encryption Standard) is a fast, symmetric encryption algorithm trusted by governments and businesses worldwide to keep sensitive data secure.

You can choose common key sizes (such as 128, 192, or 256-bit) and cipher modes, letting you balance speed and security for your use case.

Yes — AES is symmetric, so the exact same key (and settings) used to encrypt a message is required to decrypt it. Losing the key means losing access to the data.

No — all encryption and decryption happens locally in your browser, so your plaintext, ciphertext, and key never leave your device.

Yes — it is well suited for encrypting short text such as passwords, notes, or messages before storing or sharing them securely.
