I once made something similar after reading a blog post here on HN [1] just to see how easy it is to make something like this. Mine [2] uses passphrases to generate keys with the Argon2 algorithm and then uses NaCl's secretbox for encryption. I also made a version for use on streams. It's not up to snuff for industrial use, but it's really easy to use if you just want to encrypt some files with a password and also very simple if you want to modify it for your own purposes.
