## BCryptHasher
BCrypt is a password hashing function that automatically incorporates salts and offers a configurable work factor. The work factor can be used to increase the computation required to generate a hash.

You can use different BCrypt work factors for production and development modes to keep password hashing fast while working on a project.

### Manual
You can manually assign a `BCryptHasher` to `drop.hash`.
```swift
let hash = BCryptHasher(workFactor: 8)
let hash = BCryptHasher(cost: 8)
let drop = try Droplet(hash: hash)
```
