🔐 Text Encryptor
AES-256-GCM encryption. Password-protected messages.
📋 When to Use the Text Encryptor / Decryptor
The Text Encryptor / Decryptor is critical for developers, system administrators, and security-conscious users. Use it when setting up servers, generating credentials, validating security configurations, or auditing existing systems. It's built with privacy-first principles — all processing happens in your browser, so sensitive data like keys and passwords never leave your device. Perfect for production work, security audits, and educational purposes.
⚙️ How the Text Encryptor / Decryptor Works
The Text Encryptor / Decryptor uses the browser's native Web Crypto API (crypto.getRandomValues, SubtleCrypto) for all cryptographic operations. When you generate keys, hashes, or tokens, the randomness comes from your operating system's cryptographically secure random number generator — the same source used by password managers and security tools. All operations run locally in your browser; generated values are never transmitted, stored, or logged. The tool is open source for independent security audit.
How to Use the Text Encryptor
- Enter your message — Type or paste the text you want to encrypt in the "Message to encrypt" field.
- Choose a strong password — Pick a password only you and the recipient know. The encryption strength depends on your password quality.
- Click Encrypt — Your message is encrypted with AES-256-GCM and converted to Base64. Copy the result to share securely.
- To decrypt — Switch to the Decrypt tab, paste the Base64 text and enter the same password. Only the correct password reveals the original message.
Frequently Asked Questions
Is this truly secure?
Yes. AES-256-GCM is a military-grade encryption standard. The encryption happens entirely in your browser using the Web Crypto API. Your plaintext never leaves your device.
What happens if I lose the password?
The data cannot be recovered without the correct password. There is no backdoor, no password reset, and no recovery mechanism. This is by design — it's what makes the encryption secure.
Why does the encrypted text look like gibberish?
The output is Base64-encoded binary data. It contains the encrypted message, a random salt, and an initialization vector — all necessary for secure decryption.
Can I encrypt files or images?
This tool encrypts text only. For files, you'd need a file encryption tool. You could Base64-encode a small file and encrypt the resulting text, but it's not efficient for large files.
