Cryptokit.Hexa

# Module Cryptokit.Hexa

    module Hexa: sig .. end

The `Hexa` module supports the encoding and decoding of binary data as hexadecimal strings. This is a popular format for transmitting keys in textual form.

    val encode : unit -> Cryptokit.transform

Return a transform that encodes its input in hexadecimal. The output is twice as long as the input, and contains no spaces or newlines.

    val decode : unit -> Cryptokit.transform

Return a transform that decodes its input from hexadecimal. The output is twice as short as the input. Blanks (spaces, tabs, newlines) in the input are ignored. Raise `Error Bad_encoding` if the input contains characters other than hexadecimal digits and blanks.
