What Is Application ID / PID?

The Application ID (or PID) is a unique number generated when you apply for a Digital Signature Certificate through any Certifying Authority.

When you submit your DSC application:

• The Application ID is sent to your registered email ID and mobile number
• It allows you to:
  • Track DSC application status
  • Check video verification completion
  • Identify approval or rejection
  • Download the final DSC

👉 This same Application ID is required during the DSC download process, so keep it safe.

What Is Download Passcode / Download Key / Challenge Code?

After completing:

• Payment
• Identity verification
• Video verification

A Download Passcode is generated in your DSC application or eKYC account.

Important to know:

• Download Passcode
• Download Key
• Challenge Code

👉 All three terms mean the same thing, but different Certifying Authorities use different names.

This passcode is mandatory to securely download your digital signature certificate.

What Is DSC Download Utility?

A DSC Download Utility is a software tool provided by the Certifying Authority to download and install your DSC into the USB token.

Whether your DSC is issued by:

• eMudhra
• VSign
• PantaSign

👉 The DSC download process is almost the same for all authorities.
Only the utility interface may vary slightly.

Why Is Java Required for DSC Download?

Most DSC download utilities are Java-based applications. Without Java, the utility may:

• Fail to open
• Show security errors
• Stop midway during download

👉 Always install the latest version of Java before starting the DSC download process.

Importance of USB Token in Digital Signature Download

A Digital Signature Certificate cannot be downloaded without a USB token.
The USB token is a secure hardware device that safely stores your DSC.

Commonly Used New Series USB Tokens

• HYP2003
• WatchData ProxKey
• mToken

You must have any one of these supported tokens to download your DSC.

If you do not already have a USB token, you can purchase one from an authorized DSC service provider at a reasonable price.

What Is USB Token Driver?

The USB token driver allows your computer to detect and communicate with the USB token.

When you insert the token:

⚠️ Without installing the correct driver:
