Instruction:
- Submission file must be in PDF format, and all the steps of generating the required must be given in your assignment, including the OpenSSL commands or command lines.
- The secret key must be included in your submission.
- All information about your CSR and the certificate (Subject Name, Issuer Name, Signature Algorithm and Validate Period and Public Key) must be list out in your submission.
Task 1 ( 7 marks)
Use OpenSSL toolkit to generate your RSA key pairs: private key and a public key. Store your private key safe and email your public key to the lecturer. (The public key must be in the format of PEM; and the public key must be in the attachment, Subject of your email must be something like
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)
Task 4 (3 marks)
Based on the topic you have chosen in Ass 1, write a scientific report of 2-3 pages. You need to find at least 5 relevant articles from Books, Journals in the Library, or articles on the Internet to read, then summarise and write a concise report in your own words.
