Encrypt and Decrypt URL Parameters

URL parameters are often used to pass information between pages, forms, and automated processes.

They can carry values such as record IDs, user selections, reference numbers, or page settings. Because these values appear in the browser address, they may be visible or manually changed.

Encrypt Data Before Adding It to a URL

Before a value is included in a URL, it can be encrypted into an unreadable string.

This makes it much harder for users to understand or modify the original information.

Encryption can help protect:

• Record and transaction identifiers
• User or account references
• Page state information
• Form values
• Process inputs
• Temporary access details

Decrypt Data When It Is Received

When the link reaches its destination, the encrypted value can be decrypted back into its original form.

The receiving page or process can then use the information as intended, without exposing the original value in the URL.

Keep Links and Processes More Secure

Without protection, someone may edit a parameter directly in the address bar and cause the wrong record, page, or action to load.

Encrypting values before sending them and decrypting them when received helps reduce tampering and keeps the process more reliable.

Because a URL should carry information—not invite users to rewrite it.
