public abstract class MessageDigest extends Object:
Object
└ MessageDigest
Abstract base class for text-oriented message digests. Concrete algorithms are exposed as dedicated subclasses such as `SHA256`, `SHA512`, `SHA3_256` or `MD5`. This keeps the public API explicit and easy to discover while preserving the shared buffering and file-digest helpers in one place. 
import klyn.cryptography

md as MessageDigest = SHA256()
digest = md.digest("hello")
print(digest.size)
print(SHA512().digestInfo("hello").hex)
