Use this crate to add various hash functions to SQLite, including MD5, SHA1, SHA256, and SHA512.

This crate uses [rusqlite](https://crates.io/crates/rusqlite) to add user-defined scalar functions and statically linking everything. Eventually it may also support dynamic extension loading (PRs welcome).

## Usage

```rust
use sqlite_hashes::{register_sha256_function, rusqlite::Connection};

fn main() {
  let db = Connection::open_in_memory().unwrap();
  register_sha256_function(&db).unwrap();

  let sql = "SELECT hex(sha256('password'))";
  let hash: String = db.query_row_and_then(&sql, [], |r| r.get(0)).unwrap();
  assert_eq!(hash, "5E884898DA28047151D0E56F8DC6292773603D0D6AABBDD62A11EF721D1542D8");
}
```
