Expand description

Decoding and encoding of Base 16 a.k.a. hex digits.

The Base 16 encoding is defined in RFC 4648. It really is just a normal hex-encoding using the (case-insensitive) letters ‘A’ to ‘F’ as additional values for the digits.

The module defines the type Decoder which keeps the state necessary for decoding. The various functions offered use such a decoder to decode and encode octets in various forms.
