Understanding Digital Signature Certificate
A DSC is a secure digital key. It comes from a government-approved group (Certifying Authority) in India.
Related glossary terms: E-filing, Permanent Account Number, Section 44AB.
It checks who signs a digital file. The file stays the same after signing. No one can change it.
A DSC is not like a handwritten signature. It uses special codes (cryptographic tech). Each file gets a unique mark.
This mark can't be faked or changed. It keeps your files safe.
DSCs follow the Information Tech Act, 2000. This law says DSCs are as good as real signatures.
Files signed with a DSC work in court. They also work with the government.
The DSC has your name on it. It shows when it expires. It also shows who gave it to you.
You keep it on a USB stick or card. Some use a secure cloud tool (HSM). This keeps it safe.
How Digital Signature Certificate Works?
A DSC uses two special keys. One is private. One is public.
You keep the private key secret. You use it to sign files.
The public key is for others. They use it to check your signature.
When you sign, the private key locks the file. It makes a unique mark (hash).
The other person uses your public key. They unlock the mark. They check it against the file.
If the marks match, the file is real. No one changed it.
To get a DSC, give ID and address proofs. Give them to a licensed group (Certifying Authority).
They check your papers. Then they give you the DSC.
It lasts one to three years. You can use it for many things.
You can file taxes online. You can send GST forms. You can sign contracts. You can bid on work (e-tendering).
Only you can sign with it. This stops fraud.
