Text Encryptor
Encrypt and decrypt text securely using AES-256-GCM. All processing happens in your browser with no data sent to servers.
100% Private & Secure
All encryption and decryption happens locally in your browser using AES-256-GCM via the Web Crypto API. Your text and password are never sent to any server. Make sure to remember your password — we cannot recover encrypted data if you forget it.
About Text Encryptor
Securely encrypt and decrypt sensitive text using military-grade AES-256-GCM encryption. Simply enter your text and a password to generate encrypted output that only you (or someone with the password) can decrypt. All encryption and decryption happens locally in your browser using the Web Crypto API — your data never leaves your device. Perfect for securing private messages, notes, passwords, or any confidential information before sharing or storing.
What Is Text Encryptor and Why Use It?
Digital security has never been more critical. With data breaches exposing billions of records annually and cyberattacks becoming increasingly sophisticated, protecting your digital identity requires proactive measures. End-to-end encryption has become essential as data breaches expose millions of records monthly and governments expand surveillance capabilities. While messaging apps like Signal offer encryption for chats, many situations require encrypting text that will be shared through less secure channels like email, cloud storage, or social media. Our Text Encryptor uses AES-256-GCM, the same encryption standard approved by the NSA for top-secret information. The Galois/Counter Mode provides both confidentiality and authentication, ensuring encrypted text cannot be silently modified in transit. The password-based key derivation uses PBKDF2 with 100,000 iterations, making brute-force attacks computationally prohibitive. Journalists protect sensitive sources before sharing information with editors. Healthcare providers encrypt patient data for secure transmission. Developers encrypt API keys and configuration secrets for team sharing. Lawyers protect privileged communications. The encrypted output is encoded as Base64 text that can be pasted anywhere: emails, chat messages, documents, or notes. Decryption requires only the encrypted text and the exact original password. This utility leverages modern browser capabilities to perform operations locally, ensuring your sensitive data never travels over the internet. The intuitive interface makes advanced security accessible to everyone, not just technical experts. IT administrators secure new employee accounts with unique credentials. Web developers generate API keys and database passwords. Privacy-conscious users replace reused passwords across all online accounts. Security teams demonstrate password requirements during training.
How to Use Text Encryptor
- 1
Enter the sensitive text you want to encrypt in the input field.
- 2
Create a strong password that will be used to encrypt and decrypt the text.
- 3
Click "Encrypt" to generate the encrypted output using AES-256-GCM.
- 4
Copy the encrypted text and share it securely with the recipient.
- 5
The recipient can paste the encrypted text here and enter the same password to decrypt.
Common Use Cases
Secure Messaging
Encrypt private messages before sending them over email or chat platforms.
Password Sharing
Securely share account credentials with team members without exposing plain text.
Note Protection
Encrypt personal notes and diary entries before storing them in cloud notes apps.
API Key Storage
Developers can encrypt API keys and tokens for safe backup and sharing.
Tips for Best Results
- !
Use a long, random password that you have never used anywhere else.
- !
Share the password through a different channel than the encrypted message (e.g., phone call vs email).
- !
If you forget the password, the encrypted data is permanently unrecoverable — store passwords safely.
- !
AES-256-GCM is the same encryption standard used by governments and military organizations.

Frequently asked questions
Common Mistakes to Avoid
- 1
Weak Passwords
Using short or common passwords defeats the purpose of strong encryption. Always use 16+ random characters.
- 2
Storing Password with Message
Never store the decryption password in the same place as the encrypted message.
- 3
Forgetting to Test Decryption
Always decrypt immediately after encrypting to verify the password works before sharing.
How Does This Compare?
Browser Encryption vs. PGP
Advantages

- −No digital signatures for authentication
- −Less suitable for long-term archival
Did You Know?
AES-256 has 2^256 possible keys — more than the number of atoms in the observable universe.
The U.S. National Security Agency approves AES-256 for top-secret government communications.
Breaking AES-256 by brute force would require more energy than exists in our solar system.
GCM mode provides both encryption and authentication, detecting any tampering with the ciphertext.
