What Is a Digital Signature?
A digital signature is an electronic method of signing documents that verifies the signer's identity and ensures the document hasn't been altered. It's legally binding in most countries under laws like the IT Act (India), ESIGN Act (USA), and eIDAS (EU).
When Do You Need Digital Signatures?
- Contracts — Both parties sign to indicate agreement to terms.
- Proposals — Client signs to approve the proposed work and pricing.
