Story: Writing Scripts with Go

This is a story about how I tried to use Go for scripting. In this story, I’ll discuss the need for a Go script, how we would expect it to behave and the possible implementations; During the discussion I’ll deep dive to scripts, shells, and shebangs. Finally, we’ll discuss solutions that will make Go scripts work.

Why Go is good for scripting?

While python and bash are popular scripting languages, C, C++ and Java are not used for scripts at all, and some languages are somewhere in between.

ENCRYPT A FILE USING A PUBLIC SSH KEY

Generate the symmetric key (32 bytes gives us the 256 bit key):

$ openssl rand 32 -out secret.key

You should only use this key this one time, by the way. If you send something to the recipient at another time, don’t reuse it.
