Your software company wants to use the rsa method to both verify the user's identity and also to verify sent messages the company verifies the identity of the user by having the user create a three-letter key the company also periodically sends release notes to the users. in order to authenticate that the notes came from the company, it sends a three-character message as a number to demonstrate that the release notes came from them. the company chooses the prime numbers and to use in the rsa algorithm, and the public encryption key using this information, answer the questions below. pick a number between 100 and 999 for your personal code. what are the two numbers that the company sends into the world using a public message so that people can correspond with the company using rsa cryptography? what is the company's private encryption key ? explain how you arrived at this value using the extended euclidean algorithm. for your personal verification code, what encrypted message would you send to the company to verify your identity? explain how you arrived at this value using the fast-modular exponentiation algorithm. the company sends out a message with the verification code 6857, decode this number using the values given above. explain how you arrived at this value using the fast-modular exponentiation algorithm. can you verify this message if you know their decoded value should be 29,003?
