[Solved] Convert Ascii “1” to hex thats non printable and cannot be seen on network traffic [closed]

Question

Either use real encryption and decryption between your source and destination (implementation will vary depending on how you are sending the data) or just obfuscate a bit by adding a known value to the hex that is ‘only’ known by the source and destination (probably best to modulo this by 127) – essentially this is a shift cypher. This isn’t very secure but makes it a little harder to read by packet sniffing. If you want a bit more obfuscation you could have a map of the 128 possibilities to 128 different. It all depend how ‘secure’ this connection need to be.
