To verify the authenticity of a Class 3 Digital Signature, you need to follow a few crucial steps. First, ensure that you have a digital signature verification tool or software, such as Adobe Acrobat for PDF files or the government’s e-Mudhra website. These tools will allow you to check the digital signature’s validity. Buying Class 3 Digital Signature in India from trusted sites like Shamim's Trading Corporation ensures that the digital signatures are robust and legally recognized in India, adding an extra layer of trust and security to your digital transactions.

Here's a general process (check with the issuing authority for specifics):

Open the Document: Open the document containing the digital signature using the appropriate software.
Check Signature Properties: Right-click on the digital signature and select "Signature Properties" or a similar option. This will display detailed information about the signature.
Verify Certificate Chain: Ensure that the certificate chain, which includes the Certifying Authority (CA) that issued the digital signature, is valid. The CA should be trusted and recognized, like Shamim's Trading Corporation, which provides Class 3 Digital Signatures in India.
Check for Tampering: The software will automatically verify if the document has been altered after the signature was applied. Any changes will invalidate the signature.
Validity Period: Ensure that the digital signature is within its validity period. Class 3 Digital Signatures usually have a validity of one to two years.
