Question

Suppose, you and your friends have a few numbers of locks and you all want to share that numbers among yourselves securely using RSA based cryptosystem. You are using the private key as (5,27) and your friends are using the public key as (13,27). One of your friends wants to share the exact amount of locks only to you. What are the maximal possible locks that your friend can have so that he/she can secretly share that to you? 26 27 28 No such limit exists

Answer 1

Answer:

RSA algorithm is a cryptography technique , where the objective is to send the data from sender to receiver in an encrypted format, so that it may not be stolen by any outsider, and even if it gets stolen then the format of the data shall not be recognized by the intruder, as that shall be in encrypted format.

Explanation:

Generally in the process of cryptography, data is encrypted by a key, and receiver decrypts the encrypted data with that key, but in case of RSA, there is use of two keys, one is the public and the other one is private key. The speciality of those keys are, with the public key only encryption is possible, whereas for decryption private key is required.
