Text Encryption

Encrypt secret messages and decrypt text with client-side AES security keys.

All encryption and decryption happens strictly inside your browser using the Web Crypto API. No plain text, passwords, or encrypted ciphers are ever transmitted to any server.

Secure AES-GCM 256-bit encryption with PBKDF2

Client-Side Only

Local Encryption Guarantee

Encryption and decryption happen inside your browser using the native Web Crypto API. Your text, secret passwords, and encrypted ciphers are never uploaded to Tool Yaar or any third party.

About Text Encrypter

The Tool Yaar Text Encrypter is a secure, browser-native cryptographic utility designed to protect sensitive text, passwords, private notes, and confidential messages.

Unlike primitive Base64 encoding or Caesar ciphers which provide zero actual security, this tool uses the browser's native Web Crypto API implementing AES-GCM (Galois/Counter Mode) with a 256-bit key length and PBKDF2-HMAC-SHA256 key stretching.

Every encryption operation generates a unique cryptographically random salt and initialization vector (IV), ensuring that encrypting the identical message twice with the same password produces completely distinct ciphertext outputs. Everything occurs locally on your device with zero cloud tracking.

How to Use the Text Encryption

1

Choose Encrypt mode, type or paste your secret message, and provide a strong password with confirmation.

2

Click Encrypt Text (or press Ctrl+Enter). Your text is encoded into an authentic AES-256-GCM cipher with random salt and IV.

3

Copy or download the encrypted string and share it safely via email or messaging apps.

4

To read it, switch to Decrypt mode, paste the encrypted string, enter the exact password, and click Decrypt Text.
