Task 2 (7 marks)
Download a cipher document and a cipher secret, which will be available on the course webpage. Then decrypt the cipher secret to obtain a secret key, and use the secret key to decrypt the cipher document. ( The secret key has been encrypted using your public key while the encrypted document has been encrypted by use of the secret key)
Task 3 (7 marks)
Generate a Certificate Sign Request (CSR), email it to the lecturer. Then download the certificate issued by the lecturer from the course webpage . (Information of the certificate such as Subject Name, Issuer Name, Signature Algorithm and Validate Period and Public Key can be extract out from the certificate)
