# What is a digest?
A digest is just a hash.
A digest is just a [hash](https://en.wikipedia.org/wiki/Hash_function).
The most common use case for a digest is to create a content
identifier for use in [Content Addressable Storage](https://en.wikipedia.org/wiki/Content-addressable_storage)
systems:
The most common use case for a digest is to create a content identifier for use in [Content Addressable Storage](https://en.wikipedia.org/wiki/Content-addressable_storage) systems:
```go
id := digest.FromBytes([]byte("my content"))
```
In the example above, the id can be used to uniquely identify
the byte slice "my content". This allows two disparate applications
to agree on a verifiable identifier without having to trust one
another.

# Usage
While the [godoc](https://godoc.org/github.com/opencontainers/go-digest) is
considered the best resource, a few important items need to be called
out when using this package.

1. Make sure to import the hash implementations into your application

1. Make sure to import the hash implementations into your application or the package will panic.
You should have something like the following in the main (or other entrypoint) of your application:
```go
import (
_ "crypto/sha256"
_ "crypto/sha512"
_ "crypto/sha512"
)
```
This may seem inconvenient but it allows you replace the hash
implementations with others, such as https://github.com/stevvooe/resumable.
2. Even though `digest.Digest` may be assemable as a string, _always_
verify your input with `digest.Parse` or use `Digest.Validate`
when accepting untrusted input. While there are measures to
avoid common problems, this will ensure you have valid digests
in the rest of your application.

3. While alternative encodings of hash values (digests) are possible (for example, base64), this package deals exclusively with hex-encoded digests.

This package is considered fairly complete. It has been in production
in thousands (millions?) of deployments and is fairly battle-hardened.
New additions will be met with skepticism. If you think there is a
missing feature, please file a bug clearly describing the problem and
the alternatives you tried before submitting a PR.
