Frequently Asked Questions
Which MCA documents need DSC signatures?
MCA e-forms themselves are signed with a Class 3 DSC of the director or professional. Attachments like board resolutions, declarations, and consent letters often need signed copies as well, and a DSC-signed PDF is cleaner than a scanned wet signature.
Should I compress before or after signing?
Always before. MCA attachments are commonly capped at 2MB, and modifying a PDF after signing invalidates the digital signature - so compress to size first, then apply the DSC as the final step.
Are confidential corporate documents uploaded during signing?
No. The signing engine runs in your browser and only a cryptographic hash of the document is sent to your USB token through a localhost bridge. Board resolutions and agreements never leave your machine.
Can multiple directors sign the same PDF?
Yes - PDF signatures can be applied sequentially. Each signer adds their DSC signature in turn, and each signature remains independently verifiable, provided nobody edits the document between signatures.
