Free Online AES256 Text Encryption

Encrypt or decrypt text using AES-256-GCM and a password-derived key (PBKDF2-SHA256, 100,000 iterations). The envelope includes random salt, nonce and authentication tag. This tool processes bounded inputs on this server without retaining submitted content.

Inputs are sent to this server. Uploads are processed temporarily and not retained. Network diagnostics may query public resolvers or the destination website.

Example & practical use
Encrypt or decrypt text using AES-256-GCM and a password-derived key (PBKDF2-SHA256, 100,000 iterations). The envelope includes random salt, nonce and authentication tag. This tool processes bounded inputs on this server without retaining submitted content. The example below demonstrates Text; Secret; Mode.
Example input:
{
  "text": "Private message",
  "secret": "A sufficiently long passphrase",
  "mode": "encrypt"
}
Expected result (relevant fields):
{
  "algorithm": "AES-256-GCM"
}
