Encode Bytes to a Base64 string.

import Bytes.Encode as Encode


Encode.encode (Encode.sequence [ Encode.unsignedInt8 102, Encode.unsignedInt8 111, Encode.unsignedInt8 111 ])
    |> fromBytes
--> "Zm9v"


Encode.encode (Encode.sequence [])
    |> fromBytes
--> ""

Decode a Base64 string to Bytes, returning Nothing if the input contains invalid characters or has an impossible length (e.g. 1 mod 4).

toBytes "Zm9v"
    |> Maybe.map Bytes.width
--> Just 3


toBytes "not valid!!"
--> Nothing

Decode a Base64 string to Bytes without validating the input.

This is faster than toBytes but will produce garbage output if the input is not a valid Base64 string. Use this when you trust the input (e.g. it was produced by fromBytes).

toBytesUnsafe "Zm9v"
    |> Bytes.width
--> 3
