converting a binary file to HEX representation using batch file

Question

I need to convert a DLL file to HEX representation to use it as a part of string to create a sql server assembly like this

CREATE ASSEMBLY [AssemblyNameHere]
FROM 0x4D5A90000300000004000000FFFF000......continue binary data
WITH PERMISSION_SET = EXTERNAL_ACCESS

I need this to be in a batch file for many reasons, but it seems that FOR statement only suitable for text files.

Answer 1

the easiest way is with CERTUTIL command:

certutil -encodehex c:myfile.dll myfile.hex
