B Private Key Download openssl from the following link and open up a console window. http://asecuritysite.com/openssl.zip No 1 Description Use: Result Outline five encryption methods that are supported: openssl list-cipher-commands openssl version Outline the version of OpenSSL: 2 Using openssl and the command in the form: openssl prime-hex 1111 Check if the following are prime numbers: 42 [Yes][No] 1421 [Yes No Use following command to view the output file: type encrypted.bin 2 Now create a file named myfile.txt (either use Notepad or another editor). Next encrypt with aes-256-cbc 2 obase64 openssl enc -aes-256-cbc -in myfile.txt -out encrypted.bin and enter your password. Is it easy to write out or transmit the output:[Yes] [No] 3 Now repeat the previous command and add the-base64 option. openss1 enc -aes-256-cbc -in myfile.txt -out encrypted.bin base64 Use following command to view the output file: type encrypted.bin Is it easy to write out or transmit the output:[Yes)[No] Has the output changed? [Yes][No] Why has it changed? Now Repeat the previous command and observe the encrypted output. openss1 enc -aes-256-cbc -in myfile.txt -out encrypted.bin - base64 5 Now let's decrypt the encrypted file with the correct format: Has the output been decrypted correctly? enc -d-aes-256-cbc -in encrypted.bin -pass pass: napier What happens when you use the wrong password? 6 7 If you are working in the lab, now give you private key to your neighbour, and Did you manage to decrypt their message? [Yes][No] get them to encrypt a secret message for you. Now encrypt a file with Blowfish and see if you can decrypt it. Did you manage to decrypt the file? [Yes)[No] Now encrypt a file with 3DES and see if you can decrypt it. Did you manage to decrypt the file? [Yes][No] 8 9 Now encrypt a file with RC2 and see if you can decrypt it. Did you manage to decrypt the file? [Yes][No]
