- Define MD5, SHA1 and SHA256 algos
- Design typclass to handle type-specific hashing behavior
- hash digest generation
- printing to base32
- Differentiate between parts meant to be used outside (by hnix-store-*, hnix)
and parts meant to be used only internaly (in **.Internal.** modules)
- Observe that hashing "Hello World" @SHA1 and serializing to base32 gives
the same hash as the one in the thesis example
"s23c9fs0v32pf6bhmcph5rbqsyl5ak8a"
