Previously we had many different code paths all handling digests in different places, all with wildly different digest support. This commit rewrites this to use a single digest handling mechanism for all digest operations. It adds various aliases for digest algorithms, like node does. For example `sha1WithRSAEncryption` is an alias for `sha1`. It also adds support for `md5-sha1` digests in various places.
