Your example seems to be due to, paraphrasing, lack of a library rather than inability to choose one. "older approach, PuTTY developers said, was devised at a time when Microsoft Windows lacked native support for a cryptographic random number generator." So "enough of how things work" could just be "pick a modern encryption library" that doesn't come from the dark ages when t there were no random numbers Same with encodings, it requires a much lower level understanding to pick a library, you can rely on the expertise of others
