Module Cryptokit.Hexa
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 -> 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 -> 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.
