Hex Online Teks Decoder

I'm trying to do a little test here, I tried "write binary files" in delphi like TextFile. I create the exe file, but I can't write hex on it, when I use Write(Arq,Array of hex) this converts to numbers and write everything wrong. How can I write hex to a new created file, that will be an executable for Windows, I have an array of bytes with all the hex code I need, called HexCode. I'm on Delphi 7.

HexCode ={ E84E0600008D44242C89442410A100204000C744240400504000C7042404504000C744242C000000008944240C8D44242889442408E8390C0000A11850400085C074428B1D08614000A304204000894424048B4310890424E81E0C0000A118504000894424048B4330890424E80A0C0000A118504000894424048B4350890424E8F60B0000E8F90B00008B15 }

If I was a bit confused in my explanation, sorry, english isn't my first language. But what I need it's like to generate an exe, without using resources, because it's few little bytes inside my Delphi code. the pointer of my file is called "arq" that is a TextFile data type.

I'm writing a program in Java, using Spring-LDAP. I need to implement a method, which should search a user by SID. For this reason I use a filter like "&((objectClass=User)(objectSid="+sid+"))". The search doesn't work with sid in String format like "S-1-12-345677-5676743-223344-...".

Using Apache Directory Studio, I can query my AD LDAP database regulary using a filter like: (objectSid=\ff\01\03\04\1a\2b\...) successfully. Here is the objectSid in hexadecimal format.

Now, how to translate the SID from String to hexadecimal and vice versa in a program, in Java?

I have a string storing the path of file:

mystring='abc\32\32_r.png'

However, when I print out mystring. It was converted to:

abc\x1a\x1a_r.png

How to stop python from converting my text?

Lets say I have a text string :"Say Hello to My Little Friend"

A function should return hex value as:

5361792048656c6c6f20746f204d79204c6974746c6520467269656e64

I was trying to convert the bytesize to hex string in ruby.I tried various combinations of pack/unpack/chr/hex to no avail.

Here is what I managed to comeup with,

"1".bytesize.chr.to_s.split.pack('a4') => "\x01\x00\x00\x00"

As you know this wont work for larger strings, for example,

"11111111".bytesize.chr().to_s.split.pack('a4') => "\b\x00\x00\x00"

where first byte is expected to be \x0B, and

"testtttttttttttttttttttttttttttttttttttttttttt".bytesize.chr.to_s.split.pack('a4') # => ".\x00\x00\x00"

which is wrong.

i.e, just the opposite of this, Unpack 4 bytes to a signed integer, where, if the <string>.bytesize is 4294967295, it should be "\xFF\xFF\xFF\xFF".
