Aadhaar masker

Aadhaar uses Verhoeff checksum validation; this tool applies the same algorithm locally.

Mask Aadhaar numbers in screenshots and documents to reduce personal data exposure.

Use this tool for quick browser-based work when you need an answer or output immediately. Use a dedicated application or automated workflow when you need bulk processing, approvals, or repeatable production rules.

1. Enter Aadhaar — Input 12-digit Aadhaar number.
2. Validate checksum — Confirm Verhoeff checksum and format validity.
3. Use masked value — Share masked output instead of full number where possible.

• Check the result before replacing the original input.
• Watch for unit, format, encoding, and browser memory limits on large inputs.
• Keep a copy of important source material until the output is verified.

Your input is handled in the browser wherever the tool can process it locally. EpitomeTool does not add an upload step unless a tool page explicitly says so.
