What type of attacks use every possible letter number and character found on a keyboard when cracking a password?
Brute-force attacks are carried out by hackers who try to crack a password by simply trying out different combinations of characters in quick succession. The algorithm is very simple and is limited to trying out as many character combinations as possible, which is why it is also called "exhaustive search".
What is block
block-wise hashing. The process of hashing all sectors of a file and then comparing them with sectors on a suspect's drive disk to determine whether there are any remnants of the original file that couldn't be recovered. cover-media. In steganalysis, the original file with no hidden message.
Which process builds a set of hashes of sectors from the original file and examines sectors on the suspect drive to find matches?
Block-wise hashing builds a data set of hashes of sectors from the original file, and then examines sectors on the suspect's drive to see whether any other sectors match.
Which action alters hash values making cracking passwords more difficult?
Salting means adding randomly generated characters to the input values before hashing them. It's a technique that's used in password hashing. It makes the hashing values unique and more difficult to crack.
