Text Encrypt
Encrypt and decrypt text with AES-256-GCM authenticated encryption. PBKDF2-SHA256 key derivation, Base64 output.
Runs in your browserFree & unlimited
Mode
All encryption happens in your browser. Your text and password are never sent to any server.
About this tool
- 1
Enter your message
Type or paste the text you want to encrypt into the input field.
- 2
Set a passphrase
Choose a strong passphrase that will be used to encrypt and later decrypt the message.
- 3
Encrypt the text
Click Encrypt to generate the encrypted ciphertext using AES-256 encryption.
- 4
Share or decrypt
Copy the encrypted text to share it securely. Paste encrypted text and enter the passphrase to decrypt.
- Use a passphrase of at least 12 characters with a mix of words, numbers, and symbols for strong encryption.
- Share the passphrase through a different channel than the encrypted message - e.g., message via email, passphrase via text.
- Always test decryption before sending to confirm the ciphertext and passphrase work correctly together.
- The encrypted output is Base64-encoded so it can be safely pasted into emails, chats, or text fields.
- AES-256 encryption performed entirely in your browser
- Passphrase-based key derivation using PBKDF2 for strong security
- Base64-encoded output safe for copy-paste into any text medium
- One-click encrypt and decrypt with clear input/output fields
- Send confidential information like passwords or account details through insecure channels
- Encrypt sensitive notes or journal entries before storing them in cloud services
- Share private data with a colleague when end-to-end encrypted messaging is not available
- Protect text snippets in shared documents or public repositories
AES-256 is a military-grade encryption standard. Security depends on your passphrase strength - use a long, unique passphrase for maximum protection.
Without the correct passphrase, AES-256 encrypted text is computationally infeasible to decrypt with current technology.
No. All encryption and decryption happens locally in your browser. Your text and passphrase never leave your device.
