what is a public key encryption??


In public key encryption we have two keys: - one is public and another is private.We use these keys for secure communicating with each outher.Public key is used by sender to encrypt his message and private key is used by receiver to decript this message.

Example :- Suppose I want to get message from many resources so  I will distribute public key to all the user who want to send me message and I keep private key to decrypt the message which user send to me.

what is a RSA encryption ??

what is a RSA encryption ?? RSA : - Rivest-Shamir-Adleman (these are the name of RSA inventors.) RSA is a encryption algorithm which is used to send message securely in the internet.RSA is a public key algorithm widely used for secure data transmission.In public key algorithm we used two keys for data transmission : one is public and another is private key.We use public key for data encryption and private key for data decryption .  RSA is based on the principle that it is easy to multiply large numbers, but factoring large numbers is very difficult. In RSA, the public key is generated by multiplying two large prime numbers and  together, and the private key is generated through a different process involving  and . A user can then distribute his public key , and anyone wishing to send the user a message would encrypt their message using the public key. Algorithm of RSA :- Choose two large prime numbers P and Q such that P is not equals of Q. Calculate ...
