The Digest package provides the following functionality:
- Message Digest algorithms - SHA1, SHA2 and SHA3
- Blake2 Cryptographic Hash and Message Authentication Code
- Extendable Output Functions - SHAKE and XOF
- Hash Based Message Authentication Codes - HMAC
- Key Derivation Functions - HKDF and X963KDF
- Mask Generation Function - MGF1
- Base64 encoding of bytes to text strings and the reverse decoding
- Base64 PEM encoding and decoding typically used to encode and decode cryptographic keys

Digest requires Swift 5.0. It also requires that the Int and UInt types be 64 bit types.
Its documentation is build with the DocC plugin and published on GitHub Pages at this location:

The documentation is also available in the Digest.doccarchive file.
Please note that the random number functionality that used to be in the Digest package, is now in the SwiftRandom package.
