Difference between digital signature and digital …
Digital Signature is the way to sign your document or data digitally. It is achieved by 1 – creating message digest from your data using some algorithm like MD5, SHA algorithm 2- Decrypting message digest with private key and then appending this signature with document (Dont worry, this all done by smart software appliactions) — On receiving end, 1- digital signature is de-encrypted by public key to get message digest 2- then software creates message digest from actual data,document and compares whether received message digest and calculated message digest are matched. if yes then data is intact and authenticated. ————————————- Digital Certificates are certificates issued by CA(Certificate Authority) like VeriSign to ensure that PUBLIC KEY and digital signature appended with document is from authenticated party and this is assured by CA.
