Text Encryption

About Text Encryption

Encrypt and decrypt text using AES-256-GCM, the same standard used by governments and banks. Enter a passphrase and your message — the tool derives a key with PBKDF2 (310,000 iterations) and encrypts locally in your browser using the Web Crypto API. The output is a compact base64 string that includes the salt and IV. Nothing is ever sent to any server.

How to Use Text Encryption

Securely encrypt or decrypt your private messages using AES-256-GCM directly in your web browser.

1. 1

   Enter your message or encrypted string

   Type or paste the plain text you wish to encrypt, or the base64 encrypted string you need to decrypt, into the main input field.

2. 2

   Provide a secure passphrase

   Enter a strong password which the tool will use to derive a cryptographic key via PBKDF2 with 310,000 iterations.

3. 3

   Select the encryption or decryption action

   Choose the appropriate action to process your data locally using the Web Crypto API without sending any information to a server.

4. 4

   Copy the resulting output

   Retrieve the generated base64 string containing the salt and IV for encryption, or the original plain text if you performed a decryption.
