We'll choose the word "HOP".

Step 2: Convert to ASCII Values
Convert each character of "HOP" to its corresponding ASCII value:

H: ASCII value is 72
O: ASCII value is 79
P: ASCII value is 80
So, the ASCII values for "HOP" are 72, 79, and 80.

Step 3: RSA Encryption
To encrypt these ASCII values using RSA, we need to use RSA encryption parameters, which usually consist of:

n: the modulus (a product of two prime numbers, p and q)
e: the public exponent
For this exercise, you can use default parameters provided by the RSA Step-by-Step tool.

Step 4: Encrypt
Visit the RSA Step-by-Step tool and keep the default parameters:

n = 3233
e = 17
Encrypt each ASCII value using the RSA formula:

𝑐
=
𝑚
𝑒
m
o
d


𝑛
c=m
e
modn
where
𝑚
m is the ASCII value,
𝑒
e is the public exponent, and
𝑛
n is the modulus.

Calculate the encrypted values:

For ASCII value 72:
𝑐
=
7

17

Using the RSA Step-by-Step tool, the encrypted value is 2711.
For ASCII value 79:
𝑐
=
7

Using the RSA Step-by-Step tool, the encrypted value is 2081.
For ASCII value 80:
𝑐
=
8

mod3233

Using the RSA Step-by-Step tool, the encrypted value is 2214.
Step 5: Record the Three-Character Cipher Text
The three-character cipher text for the word "HOP" is composed of the encrypted values for each character:

H -> 2711
O -> 2081
P -> 2214
Thus, the three-character cipher text is:

2711
2081
2214
In summary, the RSA-encrypted ASCII values for "HOP" are:

H: 2711
O: 2081
P: 2214
Each encrypted value represents the cipher text for the corresponding character. what is the cipher text

1 answer

The cipher text for the word "HOP", based on the RSA encryption of its ASCII values, consists of the individual encrypted values for each character. Here are the encrypted values again:

  • H (ASCII 72) → 2711
  • O (ASCII 79) → 2081
  • P (ASCII 80) → 2214

Thus, the complete cipher text for "HOP" is:

2711 2081 2214

This strings of numbers represent the encrypted form of the original word using RSA encryption.
