data security encryption

Have an assignment that need to be done:

"lab name" is mb

1. Let d equal your Unicode decimal `lab name'.

Evaluate and show your working:

d17 mod 13

hint: d17 = d10  d7 and be careful of rounding errors using the website or a

calculator

2. The following message:

wqoashcgomvszzc

was encrypted using a Caeser Cipher using only lower case letters. The shift is

unknown.

Given that you know the plain text message contains the word `hello'. Determine

the shift and decrypt the message. Show your reasoning.

Thank you

IGNORE FIRST POST, SOME BIT WAS MISSING SEE THIS ONE:

"lab name" = mb

1. Let b equal your Unicode binary `lab name',
Let c be the binary representation of 2162 -1.
Encrypt your b using XOR encryption with key c. If we denote the resulting
Unicode binary ciphertext as e.
Write down e.
Then encrypt the message e using XOR encryption using b as the key. Write down
the result of this double encryption. Brie
y describe this result.
hint: These binary numbers are too large to entered into the web page directly,
you will need to split them.


2.Let d equal your Unicode decimal `lab name', from Question 1.
Evaluate and show your working:
d17 mod 13
hint: d17 = d10  d7 and be careful of rounding errors using the website or a
calculator


3.The following message:
wqoashcgomvszzc
was encrypted using a Caeser Cipher using only lower case letters. The shift is
unknown.
Given that you know the plain text message contains the word `hello'. Determine
the shift and decrypt the message. Show your reasoning.

Thank you

Hi, The first question is not clear. What are the web pages described in Lab Sheet 1? The Caesar cipher is easy and I have already solved it. If I understood properly, answers would be 1. 7143___ 2. e = 42878 Mais
