Improved "script" / "screen" unix function

I'm in need of a improved version of the linux "script" function that can capture all colors, timing of keystrokes and output that can encrypt it's data and send it over to a central server in realtime. ascii cast is the closest solution that we found but it doesn't fulfill the real-time encrypted sending. this is for a commercial product so it cannot be a fork of another project and needs to fulfill all the requirements mentioned above. it needs to be written in a language that can compile easily without requiring extra dependencies such as a go compiler or other libraries.
