password protected Aadhaar PDF signature validation
Validate a Password-Protected Aadhaar PDF Without Rewriting It
You do not need to create an unlocked replacement before starting verification. Open the original e-Aadhaar with the correct password, then check its embedded signature as a separate step.A locked PDF and an unverified signature are different issues
UIDAI describes e-Aadhaar as a password-protected electronic document digitally signed by the authority. The password controls access to the file; signature validation checks the signing evidence. Successfully opening it does not by itself establish that the embedded signature is intact and trusted.
Start with the PDF downloaded directly from the official government website. If you only have a screenshot, scan or PDF created by printing, recover the original first. Those replacements can be readable and password-free without containing the digital signature needed for verification. Keep the original filename so you can recognise it later.
Use UIDAI's password examples carefully
UIDAI's e-Aadhaar FAQ combines the first four name letters in capitals with the four-digit birth year. Its examples include SURESH KUMAR, born in 1990: SURE1990; and SAI KUMAR, born in 1990: SAIK1990. Use the name recorded on the Aadhaar, rather than a nickname or a differently spelled name.
The same FAQ gives P. KUMAR with birth year 1990 as P.KU1990, and RIA with birth year 1990 as RIA1990. These examples matter for initials, punctuation and short names. This is e-Aadhaar guidance; do not assume that another issuer's PAN, certificate or other encrypted PDF uses the same password convention.
Open the original rather than removing its password first
A verifier that accepts encrypted originals can use the password while reading the existing file. GreenTick PDF's upload flow asks for a password when one is required and distinguishes an incorrect password from a missing or unsupported digital signature. There is no need to prepare a password-free rewrite as a first step.
Avoid using Print to PDF as an unlocking shortcut. Adobe documents that printing to its PDF printer creates a PDF; that makes it an output operation rather than evidence that the source signature was preserved. Keeping and opening the signed original is the safer workflow when you want to validate what UIDAI supplied.
What to do when the password is rejected
Check capitalisation, the recorded name and the four-digit birth year first. Type the password directly if copying added a space. Confirm you selected the intended e-Aadhaar PDF rather than another person's file or a different document whose password follows different instructions. Do not send your full document and password to strangers for guessing.
If the file opens in your reader but the verification flow cannot access it, retain the exact error message and use support. If it does not open anywhere with the expected password, download a fresh original from the official source and consult UIDAI's current instructions. Repeatedly converting the locked file will not resolve a mistaken password safely.
Check the signature after access succeeds
Once the password works, continue to the signature check. A readable file can still have no usable signature, unsupported signature data or a failed validation result. GreenTick PDF creates output only when its supported signature checks pass; entering the correct password does not override a failure or guarantee a green mark.
For a manual inspection, Adobe's signature-validation guidance explains the signature panel and validation details. For a failed result, keep the reported reason and compare a fresh original. Do not add a check symbol yourself. If the official original remains unsuitable, ask the issuing service for help rather than trying to repair the signature's appearance.
Keep the original and print output separate
If GreenTick PDF successfully generates a flattened print-ready copy, inspect it before printing and retain your original signed download separately. The output supports a paper workflow; it does not preserve the live digital signature for another verifier. Use the original when a recipient asks to check the electronic signature and follow that recipient's submission rules.
On a shared computer, check the Downloads folder before leaving and remove local copies you do not need. Keep your retained original somewhere you control. Only provide the file and its password through the intended verification flow when you choose to use it; publishing either in a public support comment is unnecessary for troubleshooting.

Questions
Must I remove the Aadhaar PDF password before uploading?
No. Upload the original and enter its password when GreenTick PDF requests it. Do not create a print conversion or unlocked rewrite just to begin validation.
Does the correct password prove my digital signature is valid?
No. It opens the file. Signature integrity, supported format and certificate trust still need a separate validation result.
Can I upload a scanned Aadhaar PDF without a password?
A scan does not contain the original embedded PDF digital signature. Download the official digitally signed e-Aadhaar original before starting signature verification.
