About this tool
AES Encryptor is a free online tool. Encrypt and decrypt text or files with AES.
Enter plaintext and key, select the AES key length (128/192/256 bits) and operating mode (CBC, CTR, GCM, etc.). The tool generates encrypted ciphertext (Base64 or Hex format) and initialization vectors (IV). Enter ciphertext, key and IV when decrypting to restore it.
Encryption uses the SubtleCrypto interface of the Web Crypto API, which is an encryption API natively provided by the browser with performance close to native code. The AES-GCM mode provides encryption and authentication (tamper-proof) and is recommended for most scenarios. The key can be derived by password (PBKDF2) or entered directly.
Suitable for encrypting sensitive data (such as passwords and keys) before transmission or storage. Note that key management is important. If you lose the key, you cannot decrypt it.
AES encryption and decryption tool, which uses AES-128/192/256 algorithm to encrypt text or files, and supports CBC, CTR, GCM and other modes.
