Adds functionality for instantiating and using `Algorithm` This CL moves some methods that exist in every hashing algorithm implementation to the `Algorithm` trait; namely, `new`, `update`, and `digest`. This allows for clients to instantiate the hashing algorithms, and to call `update` and `digest` on objects that have this trait. It allows a generic representation of an algorithm that can be used. In order to avoid users of concrete instance of `Algorithm` to have to import `Algorithm` and every time they want to use the functions implemented, these functions are also included in the inherent implementation of each algorithm (as it was originally set up, except that now the methods call the equivalent method in the Algorithm implementation' This CL also adds the block size as a const field in the `Algorithm` trait. Note: this specifically supports the hashing algorithm use in the style of what is done in AOSP's `packages/modules/Virtualization/libs/apkverify`, which was previously using the rust openssl `Hasher` to instantiate algorithms specified by their `MessageDigest`.

BoringSSL is a fork of OpenSSL that is designed to meet Google's needs.
Although BoringSSL is an open source project, it is not intended for general use, as OpenSSL is. We don't recommend that third parties depend upon it. Doing so is likely to be frustrating because there are no guarantees of API or ABI stability.
Programs ship their own copies of BoringSSL when they use it and we update everything as needed when deciding to make API changes. This allows us to mostly avoid compromises in the name of compatibility. It works for us, but it may not work for you.
BoringSSL arose because Google used OpenSSL for many years in various ways and, over time, built up a large number of patches that were maintained while tracking upstream OpenSSL. As Google's product portfolio became more complex, more copies of OpenSSL sprung up and the effort involved in maintaining all these patches in multiple places was growing steadily.
Currently BoringSSL is the SSL library in Chrome/Chromium, Android (but it's not part of the NDK) and a number of other apps/programs.
