users can change their own passwords by typing passwd with ____ to specify the username.
Answer:
no agruement
Explanation:
Users can change their own passwords by typing "passwd" with the "-u" flag to specify the username.
In Unix-based operating systems, including Linux and macOS, the "passwd" command is used to change a user's password. By default, the "passwd" command will change the password for the current user who is logged in. However, if an administrator needs to change the password for another user account, they can use the "-u" flag to specify the username of the account whose password they want to change.
If the password change is successful, the system will display a message indicating that the password has been updated. It's important to note that users can also change their own passwords using the "passwd" command without the "-u" flag.

Given is a stream cipher which uses a single LFSR as key stream generator. The LFSR has a degree of 256.
1. How many plaintext/ciphertext bit pairs are needed to launch a successful attack?
2. Describe all steps of the attack in detail and develop the formulae that need to be solved.
3. What is the key in this system? Why doesn’t it make sense to use the initial contents of the LFSR as the key or as part of the key?
1. To launch a successful attack on a stream cipher using a single LFSR with a degree of 256, you need 2 * 256 = 512 plaintext/ciphertext bit pairs. This is because, in general, to determine the initial state of an LFSR of degree n, you need 2n linearly independent equations.
2. Steps of the attack:
a. Collect 512 plaintext/ciphertext bit pairs (P_i, C_i), where 1 ≤ i ≤ 512.
b. For each pair, compute the key stream bit K_i = P_i ⊕ C_i.
c. Set up a system of 256 linear equations using the key stream bits K_i.
d. Solve the system of linear equations using methods such as Gaussian elimination or Berlekamp-Massey algorithm to find the initial state of the LFSR.
e. With the initial state of the LFSR known, generate the key stream and decrypt any future ciphertexts.
The formula that needs to be solved is:
K_i = K_(i-1) * c_1 ⊕ K_(i-2) * c_2 ⊕ ... ⊕ K_(i-256) * c_256, where 257 ≤ i ≤ 512 and c_j represents the LFSR coefficients.
3. The key in this system is the initial state of the LFSR, which is a sequence of 256 bits. It does not make sense to use the initial contents of the LFSR as the key or as part of the key because the security of the system relies on the initial state being secret. If an attacker knows the initial state, they can generate the same key stream and easily decrypt the ciphertext. Furthermore, using the initial contents as the key would essentially make the key fixed and would provide no additional security.

when microsoft introduced windows 2000, it added optional built-in encryption to ntfs called ____.
When Microsoft introduced Windows 2000, it added optional built-in encryption to NTFS called Encrypting File System (EFS). EFS is a file encryption technology that allows users to encrypt files and folders on their computer. This encryption protects the data from unauthorized access and can only be decrypted by users who have the correct credentials.
EFS uses a combination of public key encryption and symmetric key encryption to secure data. Public key encryption is used to encrypt the symmetric key, which is then used to encrypt the data. This approach provides a higher level of security than just using symmetric key encryption alone.
EFS was designed for use on NTFS partitions, which are common on Windows operating systems. It can be enabled on individual files and folders or on entire directories. Users can also set permissions on encrypted files and folders to control who can access them.
Overall, EFS is a useful tool for protecting sensitive data on Windows operating systems. However, it's important to note that encryption is only one aspect of security and other measures should also be taken to ensure the protection of important data.

Assignment 5 A: Fibonacci Sequence. You may have learned about Fibonacci Sequences in high school or prior classes. To briefly summarize, it is a sequence that is created when you repeatedly add the two prior numbers in the sequence together. Here is an example of the first few numbers in the sequence: 0, 1, 1, 2, 3, 5, 8, 13, 21… In CSE 1322L, we teach students how to create this sequence using an advanced concept called recursion. In this class however, we’ll use arrays and loops. Your task is to do the following: • Prompt the user to enter the length of the Fibonacci Sequence they want to make ◦ Validate that the number is greater than 0, and keep asking them until it is • Use that number to initialize an empty array ◦ C++ Students: Watch the video posted on the FYE website or D2L to learn how to do this in your language – it’s a little different from the Java and C# approach • Initialize index 0 of the array to 0, and index 1 of the array to 1. • Using a looping structure, fill the array with the correct Fibonacci sequence values • Once the array is full, use another looping structure to print the sequence from the array Note: You must store the sequence in the array, and then print it in a separate loop from the one that created it. You can not print the values in the same loop where you create and store them in the array.
Sample Output #1:
[Fibonacci Sequence Generator]
How long should the Fibonacci Sequence be?: -15

a hash table has the items 51, 53, 54, and 56. how many buckets will a direct access table have after the operationhashinsert(hashtable, 55)?
In computer science, hash tables and direct access tables are used to store data and retrieve it efficiently. Hash tables use a hash function to map keys to buckets while direct access tables use an array to directly access the data.
In this scenario, we are given a hash table with the items 51, 53, 54, and 56. We are asked to determine how many buckets a direct access table will have after inserting the item 55 using the operation hashinsert(hashtable, 55).
To answer this question, we need to first understand the relationship between hash tables and direct access tables. In a hash table, the number of buckets is determined by the size of the table and the hash function used. However, in a direct access table, the number of buckets is equal to the largest key in the table.
Since the hash table already contains the items 51, 53, 54, and 56, the largest key is 56. Therefore, the direct access table will have 57 buckets. After inserting the item 55, the largest key will still be 56, so the number of buckets will remain the same at 57.
In conclusion, a direct access table with 57 buckets will be required to store the items 51, 53, 54, 55, and 56. The operation hashinsert(hashtable, 55) will not change the number of buckets in the direct access table.

The statement cin >> setW (10) >> stri will read up to this many characters into str. a. Nine b. Ten c. Eleven d. Eight e. None of these. 26.
The answer is nine because i took this and got it right
The statement "cin >> setw(10) >> str" will read up to 10 characters into str. So, the correct answer is option b. Ten.
The statement cin >> setW (10) >> stri will read up to ten characters into str. The setW manipulator sets the width of the input field to 10, which means that the input will be restricted to 10 characters or less. Any additional characters will not be read and will be left in the input stream. Therefore, option b is the correct answer. It is important to note that the size of the string variable str should be large enough to accommodate the input, otherwise, it may lead to buffer overflow or truncation of input.

A tool which lists all of the operating functions to be performed, their characteristics, and their timing is a "timing diagram".
A timing diagram is a graphical representation that shows the timing and relationships between different signals or functions in a system.
It is commonly used in digital electronics, computer hardware, and software design to visualize the timing and interactions between different components or processes.
A timing diagram can be used to analyze and optimize the performance of a system, identify potential timing issues or conflicts, and ensure that all functions are performed correctly and on time.
The diagram typically shows the different functions or signals as horizontal lines or bars, with arrows or vertical lines indicating their timing and duration.

which programming language uses a combination of existing technologies like javascript, css, and xml?
XUL (XML User Interface Language) is a programming language that uses a combination of existing technologies like JavaScript, CSS (Cascading Style Sheets), and XML (eXtensible Markup Language) to create user interfaces for applications. XUL is a markup language developed by Mozilla for building cross-platform applications, and it allows developers to create rich user interfaces using familiar web technologies. JavaScript is used for adding interactivity and dynamic behavior to XUL-based applications, CSS is used for styling and layout, and XML is used for defining the structure of the user interface components. XUL is commonly used in Mozilla applications like Firefox and Thunderbird for creating user interfaces for extensions and add-ons.
assume a random number generator object named randgen exists. which expression is most appropriate for randomly choosing a day of the week?a.randgen.nextint(1);b.randgen.nextint(6);c.randgen.nextint(7);d.randgen.nextint(8);
The most appropriate expression for randomly choosing a day of the week would be option C, which is randgen.nextint(7). This is because there are 7 days in a week (Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, and Sunday), and generating a random integer between 0 and 6 (inclusive) using randgen.nextint(7) would allow for each day to have an equal chance of being chosen.
Option A, which is randgen.nextint(1), would only generate a random integer between 0 and 1 (inclusive), meaning it would only randomly choose between 0 and 1, which is not enough for selecting a day of the weekOption B, which is randgen.nextint(6), would generate a random integebetween 0 and 5 (inclusive), meaning it would not be able to select Sunday.Option D, which is randgen.nextint(8), would generate a random integer between 0 and 7 (inclusive), but since there are only 7 days in a week, there would be a possibility of generating an invalid number (8) which is not desirable.
