- Imagine a Vigen'ere cypher encrypts a long string of text and repeats it in the ciphertext. Use this information to calculate the key's length.q5- The Atbash cipher is a type of monoalphabetic cipher formed by taking the alphabet and mapping it to its reverse, so that the first letter becomes the last letter, the second letter becomes the second to last letter, and so on. For example: A becomes Z and Z becomes A, B becomes Y and Y becomes B, and so on. Numeric digits and special symbols will remain the same. What does XHV2HRZ mean?The script uses the paddingoracle library to send encrypted values to the program and tries todecrypt it based on the error message. Execute it with the encrypted ciphertext as the argument.

- A __________ is an encryption technique designed to enable encryption of a message digest by a user's private key with decryption and message verification by the user's public key and hashing the unencrypted message.A cell-phone two-factor authorization is an example of using _____ to authenticate the user. Select one: a. something the user knows b. something the user has c. something the user is d. something the user doesMany user-created passwords are simple and easy to guess. Program that takes a simple password and makes it stronger by replacing characters using the key below, and by appending "q*s" to the end of the input string. i becomes ! a becomes @ m becomes M B becomes 8 o becomes . Ex: If the input is: mypassword the output is: Myp@ssw.rdq*s
- Attacks on a cipher that use letter frequency can be made more difficult by assigning multiple codes to the most frequently used letters in the alphabet. Such a cipher is called a homophonic cipher. Explain why multiple codes cause no increase in the time to decipher a message if the key is known.Attacks on a cypher are more difficult for a short message since they are more difficult to break.The ciphertext of the message " ILOVEMYUNIVERSITYVERYMUCH" after encryption by using Transposition cipher and the key =5 4 3 2 1 will be: Select one: a. ALL OTHER CHOICES INCORRECT b. IMVTY LYEYM OURVU VNSEC EIIRH c. ALL OTHER CHOICES INCORRECTT d. LYEYM OURVU VNSEC EIIRH IMVTY e. VNSEC EIIRH IMVTY LYEYM OURVU f. OURVU EIIRH VNSEC IMVTY LYEYM g.
