Select two. Protect confidentiality Protect integrity Allows you to check whether a file has been changed Allows you to check whether a file has been viewed An instance where two different pieces of data are hashed separately, but both result in a single identical hash value is described by what term? Collision Null Value Avalanche Digest A ___ attack on a hash can take advantage of similar content, or instances where part of the message has some significance to the original, and generates the same hash signature. Full context Collision Pre-image Dictionary The birthday paradox concept is employed in the birthday attack on hashes in effort to identify a _____ of a given hash. collision anomaly change LSB A pre-compiled list of hash values for possible passwords is called a ______ and is used in cracking efforts by attackers. Rainbow table Lookup table Block list Bash compiler From the list below, which term is best described as random bits added to a password hash to help with safeguarding passwords in storage? CRC Rounds Salt Rainbow Table ______ is a hash generator option for passwords that uses salt to create a non-recurrent hash. Ha$her Noesis Bcrypt Arcsight From the list below, which hash option is used in Microsoft Windows environments storing passwords that are fewer than 15 characters long?
