What are the Types of Class 3 Digital Signature Certificate
Class 3 digital signature can be issued in two categories : Signing , Signing & Encryption. Signing Certificate could only be used for signing a document whereas encryption certificate provides protection to encrypted document / information over the transmission of document / information on internet. Encryption Certificates are most popular to use on eTendering or eProcurment platforms. Encryption certificates basically secure the documents / information until it reaches to intended recipient.
Class 3 DSC : It can be issued in the name of individuals as well as organisations. These are legally valid and are used for e-commerce applications. Applicants have to appear before the certifying authority of the registration authority for obtaining class 3 Digital Signature Certificate.
Why do I require a Digital Signature Certificate ?
A digital Signatur certificate (DSC) provides an electronic means of proving your identity. It also provides a high level of security for online transactions. You can use certificates to encrypt information so that only the recipient can read it. You can digitally sign information to provide assurance that the recipient has not been modified in transit, and allow verification that actually sent the message.
How does Digital Signature Work ?
Digital Signature Certificate, in simple terms, is a file created by a Licensed Certifying Authority through encryption and is then issued to you, in the USB eToken. When signing any particular document this file is accessed, which acts like a ‘key’ (Private Key) and locks & secures the document being signed (through encryption). [This is similar to using a key in a physical lock to secure your valuables in a bank locker – a lock can only be opened by its own key].
In addition to locking the document being signed, this file also adds a Digital Certificate to it containing your identity details, viz. name, Organization’s name, email ID, etc.
It also adds a key code (known as public key) which is the same key that resides in the certifying authority server, thereby allowing the other party to validate the authenticity of your DSC. Contrary to popular myth, the DSC does NOT contain a scanned copy of your physical signature.
Who Needs a Digital Signature Certificate?
According to the Ministry of Corporate Affairs, every individual that is required to sign manual documents and returns filed with ROC is required to obtain a Digital Signature Certificate (DSC). These include:
- Directors
- Auditors
- Bank Officials – for Registration and Satisfaction of Charges
- Company Secretary – Whether in practice or in job
- Other Authorized Signatories
The Certifying Authorities are authorized to issue a Digital Signature Certificate with a validity of at least one year. A DSC is unique to each individual. If a professional has obtained a DSC, he/ she can use the same for e-filing of forms for multiple companies, provided he/ she has been authorized to do so by the respective companies. Digital Signatures are legally admissible as per IT ACT 2000 and are password protected and cannot be copied from a digitally signed document.
