I've got encrypted string (data)

data = “i]\rD\004\025\027\004_~\002\006`HZ@UBY\Ku\002O2\003_MQB\020\007G~\004Q”

and key (in hex)

key = “0x7f0b0014”

Plain text = key xor data

I tried to decrypt it in ruby,but i've failed below is the code of one of my try.

data = "i]\rD\004\025\027\004_~\002\006`HZ@UBY\\Ku\002O2\003_MQB\020\007G~\004Q"key = "7f0b0014"# key changed to an array with chars in int stored in new_keyp new_key = [key].pack("H*").split(//).each.map { |x|  x.ord } #pack("H*") used on array GIVES STRING FROM HEX #.each.map change every [value] of an array by value.ordp new_data = [data].pack("H*").split(//).each.map { |x| x.ord }nd = Array.newi,j = 0, 0 while i < new_data.length do  while j < new_key.length do    new_data[i] = new_data[i].to_i ^ new_key[j].to_i    j+=1  end  j=0  nd << new_data[i].chr  i+=1endp new_datap nd.join #OUTPUT = "M\xBD%\x14\x9EFaP\x8BL.HC\x96\xCBgn*"

I tried to:

• add a padding "000...." on the left of the key

• add a padding "....000" on the right of the key

• loop the key to the same lenght as data "7f0b00147f0b0014...7f0b0014"

The output should give me a some kind of a string in format "1227a5aa-ce82-4da8-9ba6-c49e809ba720".

Here is the working code, but key here was integer, not a string:

key = 52 # "R" data = "\005\006\006\003U\001UU\031WQ\f\006\031\000PU\f\031\rVU\002\031W\000\rQ\f\004\rVU\003\006\004"new_data = Array.newdata.split(//).each do |e|   new_data << (e.unpack("H*")[0].to_i(16) ^ key).chrendp new_data.join#OUTPUT "1227a5aa-ce82-4da8-9ba6-c49e809ba720"

I have ABC123EFFF.

I want to have 001010101111000001001000111110111111111111 (i.e. binary repr. with, say, 42 digits and leading zeroes).

How?

I know this is not difficult but I am just learning python. I need to create text file with arrays of strings from 000000000000 to all ffffffffffff. So it should looks like below:

Total 12 characters start from 0 and finished by F

Thanks a lot in advance!

I am facing a difficulty in converting hex values of string characters to normal test valuesfor example hex value of ' to sting is ' i.e an apostrophe.

Another values of hex characters can be found on this link : http://character-code.com/.

Can someone please tell me if a javascript method exists to do so or should I be using some external javascript library plug-in for this purpose?

I have already tried using URIencode and URIencodecomponent but no luck

I am searching the method to convert hex string into byte string in C++.I want to convert s1 into s2 like below pseudo code. The output of to_byte_string must be std::string.

std::string s1 = "0xb5c8d7 ...";std::string s2;s2 = to_byte_string(s1) /* s2 == "\xb5\xc8\xd7 ..." */

Is there any library function to do this kind of thing ?
