Executive Solution Overview
Secure Hash Algorithm (SHA-1) calculates a 160-bit hashed value for the targeted message. Message Digest 5 produces calculates a 128-hash value. MD5 is now considered obsolete because of the “birthday problem”. Notice the increase from 160-bit to 128-bit. Do you think more bits for the hash value makes the algorithm better? Explain your position. T…

Secure Hash Algorithm (SHA-1) calculates a 160-bit hashed value for the targeted message. Message Digest 5 produces calculates a 128-hash value. MD5 is now considered obsolete because of the “birthday problem”. Notice the increase from 160-bit to 128-bit. Do you think more bits for the hash value makes the algorithm better? Explain your position. The second question must be on a Word document. The hash value of a message is a one-way "unique value" that can be extracted from the message using algorithms like MD5 and SHA-x. In this paper, you are going to use a hash calculator (the best way to find one is to google _hash calculator)_. Cut and paste the message below into a hash calculator and compute the MD5 or SHA-1 hashed value. Once you have the hashed value, store it in a text file (notepad). Now, search for an AES encryption tool on the Internet (google: _AES encryption tool_). Paste the hashed value into the AES tool (note that you will need to create a secret password/key to use the EAS Encryption tool. Once the encryption is completed, explain the resulting value (what is it?).
