This is both a performance and security question that I'm looking for efficient and long term security with large file pushing over the internet.
My scenario is as follows. - Server receives a large amount of data (20mb+) from a growing number of clients. This is over a TLS API service publicly exposed. - Im worried about a MITM attack which could obtain said files.
Q: How would one encrypt and decrypt large files/sections without breaking performance on both ends? Is there an efficient method or Better practice in transmitting the data without increasing their size to heavily?
Note: My grandpa said homing pigeons worked well in the past
