Module eco.encoding.hex

Hex encoding/decoding utilities.

This module provides helpers to encode raw bytes into lowercase hexadecimal strings, decode hex strings back into raw bytes, and format a hexdump similar to hexdump -C.

Functions

encode (bin[, sep=''])	Encode bytes to a hexadecimal string.
decode (s)	Decode a hexadecimal string into bytes.
dump (data)	Format a hexdump of the given data.

Functions

encode (bin[, sep=''])

Encode bytes to a hexadecimal string.

Parameters:

• bin string Input bytes.
• sep string Optional separator inserted between bytes. (default '')

Returns:

string Lowercase hexadecimal string.

decode (s)

Decode a hexadecimal string into bytes.

On malformed input, returns nil, 'input is malformed'.

Parameters:

• s string Hex string.

Returns:

string out Decoded bytes.

Or

1. nil On malformed input.
2. string Error message.

dump (data)

Format a hexdump of the given data.

The format matches the output of hexdump -C.

Parameters:

• data string Input bytes.

Returns:

string Dump string (contains newlines).

Usage:

local hex = require 'eco.encoding.hex'
print(hex.dump('hello'))
