# Oracle
Oracle is a go library that provides the following cryptographic functions:
- generate key-pairs
- encrypt messages
- decrypt messages
- sign messages
- validate messages
Oracle is the basic object that can perform these functions. It also has the concept of a Peer. An Oracle is to a private key as a Peer is to a public key.
Keys are Curve25519. Messages are encrypted using ChaCha20-Poly1305 AEAD. Perfect forward secrecy is assured by making use of one-time ephemeral keys.
This project is heavily inspired by [age](https://github.com/C2SP/C2SP/blob/main/age.md), especially with respect to cryptographic design. However, I beleive that Oracle provides the following advantages, making it a better choice in some situations:
- Simpler API, doing away with unesseary abstractions
- A simple, standard format for messages (PEM)
- Package first. Oracle is first and foremost a Go package with a sensible API
- Do one thing and do it well. The companion binary `goracle` honours the Linux philosophy by accepting input from stdin and producing output to stdout, unlocking composability.
Oracle also comes with a binary called `pemreader` that reads PEM files.
