What is Text Encrypt & Decrypt?

Text Encrypt & Decrypt is an online security tool that protects your text messages and sensitive information using AES-GCM 256-bit encryption with password-based protection. It combines military-grade encryption with PBKDF2 key derivation to ensure your data remains private and secure. All processing happens directly in your browser—your data never touches external servers.

How do I use this encryption tool?

Paste or type your text into the input fieldEnter a strong password of your choiceClick "Encrypt" to generate encrypted textCopy the encrypted result and share it securelyTo decrypt, paste the encrypted text back, enter the same password, and click "Decrypt"Remember: you need the exact password to decrypt—there's no recovery option if you forget it.

Is my data safe with this tool?

Yes, your data is completely safe. This tool uses AES-256 encryption, the same standard trusted by governments and financial institutions. All encryption happens on your device—your text and password never reach any server. There's no data logging, tracking, or storage. You have full control over your sensitive information at all times.

Can I decrypt text without the password?

No, decryption requires the exact password used during encryption. This is by design—it ensures only authorized users with the correct password can access the encrypted content. If you forget your password, the encrypted text cannot be recovered. Always store passwords securely.

Is Text Encrypt & Decrypt free?

Yes, this tool is completely free to use at tools.bkns.vn. There are no hidden fees, premium features, or account requirements. You can encrypt and decrypt unlimited text without any restrictions.

This tool uses industry-standard AES-GCM (Advanced Encryption Standard in Galois/Counter Mode) with 256-bit keys to encrypt your text. When you provide a password, it's processed through PBKDF2 (Password-Based Key Derivation Function 2) to generate a cryptographically secure encryption key. This two-layer approach ensures that even if someone obtains your encrypted text, they cannot decrypt it without the correct password.

All encryption and decryption operations run entirely on your device using your browser's built-in cryptographic capabilities. Your original text, password, and encryption keys never leave your computer or connect to any server. This client-side processing model provides maximum privacy and security—you maintain complete control over your sensitive information.

The encrypted output is Base64-encoded for easy sharing and storage. Simply paste your encrypted text back into the tool with the correct password to decrypt it instantly. The entire process is transparent, fast, and requires no account or registration.
