NixBase32

Base16

^ Nix has a special map of Base32 encoding Placed first, since it determines Haskell optimizations of pattern matches, & NixBase seems be the most widely used in Nix.

Base64

encodeDigestWith :: BaseEncoding -> Digest a -> Text

Take BaseEncoding type of the output -> take the Digeest as input -> encode Digest

decodeDigestWith :: HashAlgorithm a => BaseEncoding -> Text -> Either String (Digest a)

Take BaseEncoding type of the input -> take the input itself -> decodeBase into Digest
