How it works

How to use the Encrypt & Decrypt Text

1. Paste or open your input

   Type, paste or drop a file into the left editor — or press Sample to try it.

2. Adjust the options

   Choose AES-256-GCM (recommended) or AES-CBC for compatibility with CryptoJS and OpenSSL, then enter a password.

3. Copy or download the result

   Copy or download the output — or press Swap to convert in the other direction.

About the Encrypt & Decrypt Text

Encrypt text with AES using a password, then decrypt it later with the same password. AES-256-GCM derives the key with PBKDF2-SHA256 (210,000 iterations) and detects tampering. AES-CBC uses the OpenSSL “Salted__” format, so output is compatible with CryptoJS.AES.encrypt(text, password) and openssl enc -aes-256-cbc -md md5 -a.
