AES Encryptor

Encrypt sensitive text data securely using AES (GCM/CBC) algorithms client-side.

Secure AES Encryption Online

AES (Advanced Encryption Standard) is the industry standard for symmetric encryption. This tool allows you to encrypt plaintext strings client-side using secure AES GCM or CBC modes with a secret passphrase. The secret key is derived securely via SHA-256 hashing.

AES Modes Explained

AES-GCM (Galois/Counter Mode) provides both confidentiality and data integrity authentication. It protects against tampering or modification of the ciphertext. AES-CBC (Cipher Block Chaining) is an older mode that provides confidentiality but lacks built-in authentication, making it susceptible to padding oracle attacks if not combined with a MAC.

How to use the encryptor

  1. Paste or type the text you want to encrypt into the plaintext box.
  2. Enter a strong passphrase or secret key. Keep this safe, as it is required to decrypt the text.
  3. Select the AES Mode (GCM is recommended) and Output Format.
  4. Click Encrypt Text.
  5. Copy both the Initialization Vector (IV) and the Ciphertext. You will need both to decrypt the text later.
