Recently, I've been learning about rooting/flashing android devices and I often come across web-pages mentioning "ODIN".
From my common sense, I've come to realise that it is some sort of Windows GUI software that helps you in flashing/tweaking android devices.
However, my concern is that wherever it is talked about, it is only provided as a downloadable binary blob .exe file hosted on third party file hosting services. Which raises concerns over trustworthiness of that downloadable file.
So my questions are - What is ODIN? What is the canonical website? Is it open source? If yes then, what is the canonical URL for repository?
