Question:1 Make RSA (encryption & decryption) application which inputs two price numbers from user and check the numbers are prime. User can choose the public key and application should validate this and then after this should encrypt and decrypt the word file. Question:2 Modify the above application which can calculate the digital signature of the given file and send the signature with the given file. Application should also verify the signature and validate these signature that the file is original or tempered? Note: for hashing algorithm you can use whatever algorithm you studied or whatever algorithm you found from the internet
