xorcism: kind of like encryption
It's not encryption, of course; it's just barely more than rot13. Still, it symmetrically obfuscates a message with a key, which is something.
This implementation is written in terms of the Write and Read traits.
Features
This package has a single feature, bin, which is enabled by default.
When enabled, bin produces a binary xorcism which enables command-line usage of this package.
To disable production of the binary and just use the library, include this as
xorcism = { version = "*", default-features = false }
