Encrypting a file posted September 2018
Encrypting a file is hard. I often need to do it to protect confidential data before sending it to someone. Besides PGP (yerk) there doesn't seem to be any light tools to do that easily. The next best option is often to have a common messaging app like Signal. So I made my own. It's called Eureka and it's available in binaries or if you have Golang installed on your device, directly by doing this:
$ go get github.com/mimoo/eureka
It's also 100 LOC. It's just doing a simple job that seems to be missing from most default tooling.
