## API
### `shasum(input, algorithm = 'sha1', encoding = 'hex')`

Compute the hash for the given input.
- `input` - a string, buffer or JSON object. objects are stringified using [`fast-safe-stringify`](https://github.com/davidmarkclements/fast-safe-stringify).
- `algorithm` - the hash algorithm to use. see [`crypto.createHash`](https://nodejs.org/api/crypto.html#crypto_crypto_createhash_algorithm_options).
- `encoding` - how to encode the hash result. see [`hash.digest`](https://nodejs.org/api/crypto.html#crypto_hash_digest_encoding).
