Describe a Computationally Secure Pseudo Random Number Generators (CSPRNGs), what does it do, and why is it important to encryption functions?

Please answer both questions, exactly with explanation: # A password generator creates a 10-character case-sensitive alphanumeric (a-zA-Z0-9) password keyed by pseudo-random number generator that has deterministic output based on a 32-bit seed (e.g., a 32-bit integer) provided by the user. How many passwords are possible? If it takes .0001 seconds to check a password, what will the average length of time be for a successful brute force attack?

This may be used to explain why certain block cypher modes of operation utilise encryption alone, whereas others use encryption and decryption together:

A block cipher with a random key is most like a Choose one: Private random function Public random permutation Private random permutation Public random function

Please describe the techniques of Substitution Cipher and Transposition Cipher.

Correct answer will be Upvoted else downvoted. Thank you! Monoalphabetic ciphers are stronger than Polyalphabetic ciphers because frequency analysis is tougher on the former. i) True ii) False

In RSA encryption, if the public key is 299, what is the private key? (Enter your answers as a comma-separated list.)

Part 2: Perform encryption and decryption using the RSA algorithm for the following. Show all your steps. 1. p = 3;q=11, e = 7; M = 5 2. p=5;q=11, e = 3; M = 9

Asymmetric ciphers are more secure because they use non-reversible procedures. This chapter introduced asymmetrical operations. If so, what are some asymmetric operations?
