I apologize for not being able to submit my entry on time due to a power outage in my area.
I noticed that none of the other contestants have provided you with a satisfactory solution. I kindly request you Reconsider my entry #20,
I would appreciate it if you could give me a chance to present you with the solution.
Check Out: #20
My expertise is in cryptography. The string was not only base64 encoded but also encrypted with a secret key that you supplied. Most people overlooked the encryption step and assumed it was just a simple encoding.
The encryption technology used in this case is complex and requires a thorough guide. However, this cannot be done in a Contest Entry due to the limited time and space.
I have set up a GitHub repository to share the real-time progress of this project. You can access it and learn about the encryption method that is used here.
The Github repo link is here.
Was this encryption used in a specific software, system, or protocol? If so, what is it?
How was the encryption key generated? Was it derived from a password, randomly generated, or based on some other information?
Is there any other information or metadata associated with the encrypted string or key?
Based on the information provided, it is difficult to identify the specific encryption technology used without further context or clues. There are numerous encryption algorithms and ciphers available, each with different properties and characteristics.
If you can provide any additional information, clues, or context regarding the encryption technology used, I'll be happy to assist you further in determining the cipher.
