Prompt

Artemis Financial is looking to encrypt their archive files and they need advice from you, as the developer and security expert, on employing best practices for encrypting their long-term archive files. You will need to research and identify the best and most secure cipher available today to recommend to Artemis Financial. Ultimately, you will recommend the algorithm cipher for file encryption that is most appropriate for their needs.

Your recommendations should be documented and delivered to Artemis Financial. This work will inform your continued work with Artemis Financial in Project Two. However, the specifics of this assignment will not be required as a deliverable in Project Two.

Address the following in your recommendations to Artemis Financial:

Algorithm Cipher: Review the scenario and the Java Security Standard Algorithm Names, a standard list of algorithm ciphers provided by Oracle for recommending an appropriate encryption algorithm cipher. Specifically, recommend an appropriate encryption algorithm cipher to deploy given Artemis Financial’s needs. Consider the following in your decision-making process:
- Consider security protection best practices to defend against various types of security attacks.
- Consider and identify all of the risks in your recommendation.
- Consider the most current government regulations and how they will be met.
- How will this algorithm cipher be used?
- What is the best cipher and why?
- What are the reasons why you might not choose the most secure cipher?

Justification: You have been asked to provide a brief overview of the encryption algorithm cipher, its advantages, and its disadvantages to justify your reasoning to Artemis Financial. Consider the following:
- What is the purpose of the hash functions and bit levels of the cipher?
- Explain the use of random numbers, symmetric vs non-symmetric keys, and so on.
- Describe the history and current state of encryption algorithms.

ASSIGNMENT
AES has been proposed as a possible algorithm name for Artemis Financial.
TLS AES 128 GCM SHA256 is part of the cypher suite.
Using three different key lengths, the Advanced Encryption Standard (AES) encrypts and decrypts 128 bits of plaintext in each block (128, 192, and 256 bits). AES is widely used, extensively tested, and secure. C and Java can both be used to implement it. ("Advanced Encryption Standard (AES) - GeeksforGeeks", 2022)
In today's world, AES is one of the most popular symmetric encryption algorithms. Security experts deciphered the DES (Data Encryption Standard), which it was designed to replace. To remedy the major fault of its predecessor, a short encryption key length that was vulnerable to brute force attacks, this new method was designed (2021).
To replace DES, AES was developed and is currently considered to be safe. Using AES, you can encrypt data in blocks of 128 bits with keys as small as 128 bits.
It has the benefit of preventing brute force attacks and having the flexibility to grow in the future.
AES has the following advantages or benefits:
Security protocols that are implemented in both hardware and software are the strongest.
Encryption key sizes range from 128 bits on up to 256 bits, depending on the level of security desired. So, the AES algorithm is more difficult to crack.
For a wide range of applications, such as wireless communication, financial transactions and e-business, encrypted data storage, and so on, it is the most extensively used security protocol available. Commercially and openly, it's one of the most widely utilized solutions in the world.
Nobody has access to your private data.
Approximately 2128 attempts are needed to break 128-bit encryption. There are few ways to break into it, making it extremely secure.
On the security front 256-bit encryption is used,
