Protect Text with Encrypt Online

This page encrypts short text with a passphrase in your browser. Test decryption before sharing, use a unique passphrase, and send that passphrase through a separate channel.

How do I use this tool?
  1. Select the encryption type (example: AES or DES) using the Encryption Type dropdown.
  2. Enter the data (string, text, json, xml, or others) you would like to encrypt.
  3. Enter a encryption passphrase to be used during the encryption process.
  4. Click the "Encrypt" button.
  5. View the encryption result in the large text area on the right hand side of the screen.
Supported Encryption Algorithms

Decrypting Your Encrypted Data

To decrypt your encrypted text, use the Encrypt Online decrypt tool.

What type of input can be encrypted?

You can enter any string value into the tool above. These values include strings like:

  • Text
  • Strings
  • JSON
  • YAML
  • Config files
  • and more!
Common Use Cases for Text Protection

Encryption is vital for various personal and professional scenarios, such as:

  • Protecting a short note during a one-time handoff
  • Testing an encrypt-and-decrypt workflow with harmless sample data
  • Keeping plaintext out of a channel that only needs to carry ciphertext
  • Using a separate passphrase channel when a managed sharing system is not available

Visit our Guides section to explore how encryption can be used in these and other scenarios.

Learn More About Encryption

Encryption converts plaintext data into a coded format, making it unreadable without the correct decryption key. This security measure is essential for protecting sensitive information from unauthorized access.
