AES Encrypt & Decrypt: popular Google search intents
Most visitors paste plaintext or ciphertext, need AES-GCM or AES-CBC with a key and IV, choose Base64 or HEX, then copy the encrypted or decrypted output immediately. The page keeps encrypt, decrypt, copy, and clear controls before key generation, PBKDF2, and compatibility details on mobile.
What this tool is for
Paste plaintext or ciphertext, choose Encrypt or Decrypt on the first screen, copy the result, then adjust AES-GCM, AES-CBC, key size, IV, PBKDF2, Base64, or HEX options below.

Frequently asked questions
Is AES Encrypt & Decrypt free?
Yes. ToolNest provides AES Encrypt & Decrypt as a free browser-based utility.
Does AES Encrypt & Decrypt require an account?
No account is required. Open the tool and use it directly in your browser.
Does AES Encrypt & Decrypt run AES encryption in the browser?
Yes. The tool uses browser cryptography where available, generates random keys and IVs locally, and lets you copy ciphertext, plaintext, or an operation report without creating an account.
Should I use AES-GCM or AES-CBC in AES Encrypt & Decrypt?
Use AES-GCM for new work because it provides authenticated encryption. AES-CBC is included for older compatibility and needs a unique IV plus padding; it does not provide the same built-in tamper detection.
What format should I use for AES key, IV, and output?
Base64 is compact for copying ciphertext, keys, and IVs between tools. HEX is useful for byte-level debugging. The key length must match 128, 192, or 256 bit AES, and the IV should be unique for every encryption.
How do I use AES Encrypt & Decrypt?
Open the AES Encrypt & Decrypt page, enter or paste your values, use the visible controls, and copy the result from the first working area. It is grouped with Encoding & Parsing for quick browsing.
Can I copy results from AES Encrypt & Decrypt?
Yes. ToolNest tools are designed around copy-ready output, so you can reuse the result in documents, spreadsheets, code editors, forms, or messages without creating an account.
