AES Encrypt / Decrypt

Convert plaintext to OpenSSL-compatible AES ciphertext and back using a shared passphrase. Encrypt and decrypt text with AES using a passphrase (CryptoJS).

Introduction

AES Encrypt / Decrypt is a free, browser-based utility in our Crypto & Security Tools collection. Convert plaintext to OpenSSL-compatible AES ciphertext and back using a shared passphrase. AES Encrypt Decrypt provides a quick CryptoJS AES demo for local experiments - not a substitute for production KMS. Everything runs locally in your browser — inputs stay on your device, with no account or upload required. Highlights include encrypt & decrypt.

FAQs

Demo-only. Prefer vetted libraries and key management in production.

CryptoJS AES with passphrase key derivation (OpenSSL-compatible).

No.

Yes. AES on EverydayDevTools is free, with no account, watermarks, or usage caps for normal interactive use.

No. AES runs in your browser. Your input is processed locally and is not sent to EverydayDevTools servers.
