Working with sensitive data during development? Need a quick way to encrypt or decrypt content without writing scripts or using third-party services?
The Encrypt & Decrypt tool from Goonlinetools lets you encrypt and decrypt text directly in your browser using strong AES encryption – with full control and zero dependencies.
🔐 What It Does
This browser-based tool allows you to:
- 🔒 Encrypt text with a custom password
- 🔓 Decrypt text using the same password
- Copy or paste encrypted/decrypted content instantly
It’s helpful for sending secure messages, generating encrypted blobs for front-end apps, or testing crypto flows in your project.
💡 How It Works
- Uses AES (Advanced Encryption Standard) for symmetric encryption
- Password-based encryption: whatever you encrypt can only be decrypted with the same key
- Everything runs locally in the browser using JavaScript (
crypto-js) - No server involved — your data stays with you
⚙️ Key Features
✅ AES-256 Encryption
Uses strong AES encryption under the hood via the popular crypto-js library. Reliable and widely used in web applications.
✅ Simple, Two-Way Interface
The interface has two main modes:
- Encrypt Mode: Enter plain text and a password → get encrypted output
- Decrypt Mode: Enter encrypted text and the password → get original text
✅ Password-Protected
Encryption is only possible with a user-defined password. Without the correct password, decryption fails — so it's secure for basic use cases.
✅ One-Click Copy
Both encrypted and decrypted results come with a copy button so you can paste them where needed quickly.
✅ 100% Client-Side
The tool runs entirely in your browser:
- No data is sent or stored
- No tracking or requests
- Works offline after load
🧪 Use Cases
This can come in handy when:
- You want to send sensitive info over chat/email, but keep it protected
- Testing AES encryption in a frontend app without writing code
- Creating hidden values for configuration or local use
- Quickly decrypting data blobs from other encrypted systems
