|
|
Hi There,
From old topic in this forum, one of decode function as below :
Code: |
local b='ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/'
function bec(data)
return ((data:gsub('.', function(x)
local r,b='',x:byte()
for i=8,1,-1 do r=r..(b%2^i-b%2^(i-1)>0 and '1' or '0') end
return r;
end)..'0000'):gsub('%d%d%d?%d?%d?%d?', function(x)
if (#x < 6) then return '' end
local c=0
for i=1,6 do c=c+(x:sub(i,i)=='1' and 2^(6-i) or 0) end
return b:sub(c+1,c+1)
end)..({ '', '==', '=' })[#data%3+1])
end
function bdc(data)
data = string.gsub(data, '[^'..b..'=]', '')
return (data:gsub('.', function(x)
if (x == '=') then return '' end
local r,f='',(b:find(x)-1)
for i=6,1,-1 do r=r..(f%2^i-f%2^(i-1)>0 and '1' or '0') end
return r;
end):gsub('%d%d%d?%d?%d?%d?%d?%d?', function(x)
if (#x ~= 8) then return '' end
local c=0
for i=1,8 do c=c+(x:sub(i,i)=='1' and 2^(8-i) or 0) end
return string.char(c)
end))
end
-- Testing
word="This is test for decoding"
deco=bec(word)
print(deco)
---give result :
VGhpcyBpcyB0ZXN0IGZvciBkZWNvZGluZw==
---- now when try to reverse it back
words='
VGhpscyBpcyB0ZXN0IGZvciBkZWNvZGluZw== '
reve=bdc(wprds)
print(reve)
--- result : Thi?́?́ѕ?Ё?ȁ??
|
is there any mistakes in the function above ?
Thanks for hints or solve the problem

Seems you just can't copy and paste correctly...
Code: | local b='ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/'
function bec(data)
return ((data:gsub('.', function(x)
local r,b='',x:byte()
for i=8,1,-1 do r=r..(b%2^i-b%2^(i-1)>0 and '1' or '0') end
return r;
end)..'0000'):gsub('%d%d%d?%d?%d?%d?', function(x)
if (#x < 6) then return '' end
local c=0
for i=1,6 do c=c+(x:sub(i,i)=='1' and 2^(6-i) or 0) end
return b:sub(c+1,c+1)
end)..({ '', '==', '=' })[#data%3+1])
end
function bdc(data)
data = string.gsub(data, '[^'..b..'=]', '')
return (data:gsub('.', function(x)
if (x == '=') then return '' end
local r,f='',(b:find(x)-1)
for i=6,1,-1 do r=r..(f%2^i-f%2^(i-1)>0 and '1' or '0') end
return r;
end):gsub('%d%d%d?%d?%d?%d?%d?%d?', function(x)
if (#x ~= 8) then return '' end
local c=0
for i=1,8 do c=c+(x:sub(i,i)=='1' and 2^(8-i) or 0) end
return string.char(c)
end))
end

Zanzer sir,
by use same encode / decode function, why decode function give wrong result when try to reverse back the code ?
From old post in this forum
http://cheatengine.org/forum/viewtopic.php?p=5659431&sid=c3ccb9b553007ff9abeb78b90186b87c
Code: |
local b='ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/'
function bec(data)
return ((data:gsub('.', function(x)
local r,b='',x:byte()
for i=8,1,-1 do r=r..(b%2^i-b%2^(i-1)>0 and '1' or '0') end
return r;
end)..'0000'):gsub('%d%d%d?%d?%d?%d?', function(x)
if (#x < 6) then return '' end
local c=0
for i=1,6 do c=c+(x:sub(i,i)=='1' and 2^(6-i) or 0) end
return b:sub(c+1,c+1)
end)..({ '', '==', '=' })[#data%3+1])
end
function bdc(data)
data = string.gsub(data, '[^'..b..'=]', '')
return (data:gsub('.', function(x)
if (x == '=') then return '' end
local r,f='',(b:find(x)-1)
for i=6,1,-1 do r=r..(f%2^i-f%2^(i-1)>0 and '1' or '0') end
return r;
end):gsub('%d%d%d?%d?%d?%d?%d?%d?', function(x)
if (#x ~= 8) then return '' end
local c=0
for i=1,8 do c=c+(x:sub(i,i)=='1' and 2^(8-i) or 0) end
return string.char(c)
end))
end
---- already Encrypted Data
deco=bdc('NjAgOUIgMDMgNjYgNDAgNjUgMDEgNkMgMDYgNjUgMDEgNkMgMDUgNjUgMDEgNkMgMDggNjUgMDEgNkMgMDk=')
print(deco)
--- result : 60 9B 03 66 40 65 01 6C 06 65 01 6C 05 65 01 6C 08 65 01 6C 09
deco2=bdc('SUp4REJDPT0= ')
print(deco2)
-- result : IJxDBC==
|
Is the second code use other method while encoding ?
Is it same base64 encoding system ?
Regards

Where did you get 'SUp4REJDPT0=' from?
What is it supposed to decode into?

Actually that from Critical Ops. trainer made by Cyber Hack
save[5]=bdc(SUp4REJDPT0=)
this is not follow the function bdc(data)
I think it given wrong decode because of this :
Code: |
local function browser(text, key)
return text:gsub("%a", function(t)
local base = (t:lower() == t and string.byte('a') or string.byte('A'))
local r = t:byte() - base
r = r + key
r = r%26 -- works correctly even if r is negative
r = r + base
return string.char(r)
end)
end
local function PIDD(text, key)
return browser(text, -key)
end
Scanning = {
browser = browser,
PIDD = PIDD,
}
--- and also
function scan(enter, exit)
pretemp1 =Scanning.PIDD(enter,12)
pretemp2 =Scanning.PIDD(exit,12)
temp1 = bdc(pretemp1)
temp2 = bdc(pretemp2)
temp3 = Scanning.PIDD(temp1,12)
temp4 = Scanning.PIDD(temp2,12)
search = bdc(temp3)
change = bdc(temp4)
aobs = AOBScan(search, "+W")
if(aobs == nil) then
scanCheck=false
else
j = stringlist_getCount(aobs)
for i = 1, j do
address=stringlist_getString(aobs,i-1)
for i = 1, string.len(change), 3 do
z = string.sub(change, i, i+2)
x, y = string.find(z, "%?+")
if (x == nil) then
script=[[
]]..address.."+"..(DEC_HEX((i-1)/3))..[[:
db ]]..z..[[
]]
autoAssemble(script)
end
end
end
object_destroy(aobs);
aobs=nil
scanCheck=true
end
end
|
of course i can see AOB code by insert print() statement at :
Code: |
...
search = bdc(temp3)
print(search)
change = bdc(temp4)
print(change)
...
|
Anyhow AOB is not important. Which I am curious is about encode decode system using temp (maybe store in memory) and then load it with function scan and change.
This is very good (to make leecher / steal code hardest).

I don't think it makes leachers/stealers any harder
They just copy it including the encoded strings without understanding what it does

If the trainer is not a online trainer,
decode function must be there inside the trainer script.
Check it out..
