I tried to reverse this function in order to convert the byte into strings , I could not do that
How can this be done

Code:

function string_tohex(str)
return (str:gsub('.', function (c)
return string.format ('%02X' ,string.byte(c)) end))
end

Code:

function fromhex(s)
return s:gsub("%w%w",function(c)
return string.char(tonumber(c,16))
end)
end

1st Test:

Code:

function string_tohex(str)
return (str:gsub('..', function (c)
return string.format ('%02X' ,string.byte(c)) end))
end

function fromhex(s)
return s:gsub("%w%w",function(c)
return string.char(tonumber(c,16))
end)
end

print(string_tohex("cheat engine"))
--- result : 636865617420656E67696E65

print(fromhex("636865617420656E67696E65"))
--- result : cheat engine 12

2nd Test:

Code:

function string_tohex(str)
return (str:gsub('.', function (c)
return string.format('%02X', string.byte(c))
end))
end

function string_fromhex(str)
return (str:gsub('..', function (cc)
return string.char(tonumber(cc, 16))
end))
end

print(string_tohex("cheat engine"))
-- result : 636865617420656E67696E65

print(string_fromhex("636865617420656E67696E65"))
-- result : cheat engine
