A user has created a new program and wants to distribute it to everyone in the company. The user wants to ensure that when the program is downloaded that the program is not changed while in transit. What can the user do to ensure that the program is not changed when downloaded?

• Install the program on individual computers.

• Turn off antivirus on all the computers.

• Create a hash of the program file that can be used to verify the integrity of the file after it is downloaded.

• Encrypt the program and require a password after it is downloaded.

• Two different files can be created that have the same output.

• It is a one-way function and not reversible.

• It can take only a fixed length message.

Algorithm that produces a 128-bit hash value

• MD5

• SHA

• RSA

• PKI

A _________________ attack uses a file containing common words, phrases, and passwords.
