Digital Signature vs Electronic Signature: Kya Jaanna Zaroori Hai

Confusion Ko Door Karein

"Digital signature" aur "electronic signature" aksar ek dusre ki jagah use hote hain, lekin technically ye alag hain:

• Electronic signature (e-signature): Sign karne ki intent ka koi bhi electronic indication
• Digital signature: Cryptographic technology use karne wala ek specific type

Sabhi digital signatures electronic signatures hain, lekin sabhi electronic signatures digital signatures nahi hain.
