Difference Between Digital Signature and Electronic Signature in India

Overview

The difference between Digital Signature and Electronic Signature is often misunderstood because both methods are used to approve documents online. Companies sign incorporation forms, tax filings, agreements and internal approvals electronically. However, these methods do not work in the same way or provide the same technical evidence.

An electronic signature is the wider legal category. A digital signature is a specific cryptographic form of electronic signature. Understanding the difference between Digital Signature and Electronic Signature helps businesses choose an accepted method and preserve reliable signing evidence.

What Is an Electronic Signature?

Under the Information Technology Act, 2000, an electronic signature means authentication of an electronic record through an electronic technique specified in the Second Schedule and includes a digital signature. This definition is central to the difference between Digital Signature and Electronic Signature because electronic signature is the broader statutory term.

A recognised method should identify the signer and indicate approval. Typed names, scanned signatures, OTP approvals and click-to-accept actions may show consent, but they are not automatically statutory electronic signatures.

What Is a Digital Signature?

A digital signature authenticates an electronic record through an asymmetric cryptosystem and a hash function. The signer uses a private key to create the signature, while the public key verifies it. This technology is the main difference between Digital Signature and Electronic Signature.

A digital signature is not an image of a handwritten signature. It is electronic data mathematically linked to the signer and document. If the document is changed after signing, verification may fail.

The simplest explanation of the difference between Digital Signature and Electronic Signature is that a digital signature is a type of electronic signature, but every electronic signature is not necessarily a digital signature.

Key Difference Between Digital Signature and Electronic Signature

The following table explains the difference between Digital Signature and Electronic Signature on legal, technical and practical grounds.

The difference between Digital Signature and Electronic Signature is not simply “secure versus insecure.” A properly implemented eSign process can create a recognised digital signature.

How Does a Digital Signature Work?

Signing software creates a unique hash of the document. The signer’s private key signs that hash and attaches the resulting data to the file. During verification, the public key checks the signature against a fresh hash.

If both values match, it indicates that the signed content has not been altered. This integrity check is an important difference between Digital Signature and Electronic Signature.

The private key must remain under the subscriber’s control. Businesses should restrict access to the DSC token, PIN and signing credentials.

What Is a Digital Signature Certificate?

A Digital Signature Certificate, or DSC, connects the certificate holder’s verified identity with a public key. Understanding a DSC is necessary when discussing the difference between Digital Signature and Electronic Signature.

A DSC generally contains the subscriber’s name, public key, validity, serial number and details of the issuing Certifying Authority. Certifying Authorities are licensed and regulated by the Controller of Certifying Authorities.

A DSC supports verification by connecting an identified subscriber with the relevant public key. This framework is another difference between Digital Signature and Electronic Signature.

Businesses needing a certificate for incorporation, tenders or statutory filings can apply for a Digital Signature Certificate online through Ebizfiling.

What Is eSign?

eSign enables an authenticated user to digitally sign online without a conventional physical token. It may include consent, approved authentication, certificate issuance and an audit trail.

This is important when understanding the difference between Digital Signature and Electronic Signature. eSign is not merely an OTP placed on a document. An OTP or biometric step may authenticate the user, while the eSign system creates the digital signature.

A short-validity certificate and one-time signing key may be generated for the transaction, while a token-based DSC may be used repeatedly. This creates another practical difference between Digital Signature and Electronic Signature.

Legal Validity in India

Sections 4 and 5 of the Information Technology Act recognise electronic records and electronic signatures, subject to prescribed requirements. Section 10A provides that a contract cannot be treated as unenforceable only because its proposal, acceptance or revocation was communicated electronically.

The legal difference between Digital Signature and Electronic Signature depends on whether the technique is recognised and electronic execution is permitted.

A valid signature does not correct every legal defect. Capacity, authority, consent, stamp duty, registration and witnessing requirements must still be checked.

A person cannot insist that every authority accept every document electronically. Portal rules must be followed. This is a practical difference between Digital Signature and Electronic Signature because many platforms prescribe DSC-based signing.

Documents Requiring Special Legal Review

The First Schedule to the Information Technology Act excludes certain documents and transactions. Following the 2022 amendment, the exclusions include certain negotiable instruments, subject to specified exceptions; powers of attorney, subject to limited exceptions; trusts; and wills or other testamentary dispositions.

The earlier blanket exclusion for immovable-property contracts was removed, although such documents may still require stamp duty, registration and witnesses.

Therefore, the difference between Digital Signature and Electronic Signature is only one part of legal review. Parties should confirm that electronic execution is permitted and identify any additional formalities.

Uses of Digital Signatures in India

Digital signatures are commonly used for incorporation, MCA forms, GST, tax filings, tenders, intellectual-property applications and import-export documentation. A new business may require a DSC during company registration in India. Existing entities may use it for MCA filing services and ROC submissions.

Companies and LLPs may also use DSCs for GST registration and specified GST portal activities. Businesses requiring ongoing assistance can use GST return filing services. This statutory use demonstrates the practical difference between Digital Signature and Electronic Signature. The accepted method depends on the form, applicant category and portal requirements.

Other Services Where Digital Signing May Be Relevant

Digital authentication may also arise in tax, intellectual-property, import-export and labour compliance.

Businesses can obtain assistance with business income-tax return filing, while brand owners can use trademark registration services. Importers and exporters can apply for IEC registration online. Employers may also obtain support for EPF registration and PF return filing.

These examples show that the difference between Digital Signature and Electronic Signature matters across compliance systems. The receiving portal decides which method is accepted.

Uses of Electronic Signatures

Electronic-signing processes may be used for employment letters, vendor agreements, onboarding, purchase orders, internal approvals, consent forms and standard commercial contracts.

The difference between Digital Signature and Electronic Signature becomes more important as transaction value or dispute risk increases. Internal approval may require less authentication than a statutory filing.

A business should check signer verification, consent, document integrity and the audit trail.

Before adopting an electronic signing workflow, a business should prepare a written policy covering authorised signers, approval limits, document retention, access controls and incident reporting. Employees should understand when a DSC is mandatory and when another approved method may be used. Periodic reviews can also identify expired certificates, inactive users, shared credentials and missing audit records before these issues affect a filing or commercial transaction.

Advantages and Limitations

Digital signatures provide certificate-based identity verification, detection of post-signing changes and independent verification. This technical difference between Digital Signature and Electronic Signature explains why DSCs are commonly required on regulated portals.

A DSC must be obtained and renewed, and token-based signing may require compatible software.

Electronic signing offers remote execution, faster approvals and audit trails. Its evidentiary strength varies, and a typed or scanned signature may provide weaker proof than recognised eSign.

The difference between Digital Signature and Electronic Signature should therefore be assessed according to convenience and risk.

Which Method Should a Business Choose?

Choose a digital signature when:

• A regulatory portal specifically requires a DSC
• Independent verification is important
• Post-signing changes must be detectable
• The signer regularly completes statutory filings
• Strong certificate-based identity evidence is needed

Choose another accepted electronic-signature process when:

• Electronic execution is legally permitted
• The receiving platform supports the method
• The signer needs remote execution
• Identity and consent are recorded
• A reliable audit trail is generated

The practical difference between Digital Signature and Electronic Signature is not about convenience alone. Businesses should review the document, law, portal instructions and required evidence.

Misunderstandings on Digital Signature and Electronic Signature

Several misconceptions create confusion about the difference between Digital Signature and Electronic Signature:

• A scanned handwritten signature is not a digital signature.
• A DSC is not an image of a signature.
• An OTP alone is not automatically a statutory electronic signature.
• eSign can create a legally recognised digital signature.
• A digital signature may fail verification if the content is altered.
• A DSC token and PIN should not be shared.
• Certificate expiry does not automatically invalidate a signature created while the certificate was valid.
• Every electronic approval method does not provide the same evidence.

Long-term verification may require preservation of certificates, revocation information and signing-time evidence.
