How secure is asymmetric encryption when sender encrypts with private key and reciever decrypts with public key but public key has visibility? any one can decrypt it

It's the other way around.. Sender encrypts with public key, and receiver decrypts with its private key..

What you are saying applies to signature.. sender signs with private key, receiver validates signature with public key

  • thanks for your comment but I read in the article that sender encrypts with private key and reciever decrypts with public key .but I guess this process is vulnerable – user3535720 Jan 30 '15 at 18:40
  • Well, to be fair, "signing" with a private key is actually encrypting the message or a digest (hash/checksum) thereof, and the receiver validates by decrypting using the public key. And depending on the algorithm, private and public key may sometimes be used for both directions. – Arc Jan 30 '15 at 18:41
