bin2hex tool

Initial release of the bin2hex.exe tool.

A tool to convert binary files to text (hex) and back to binary. It can be used as a poor person's binary editor.

Usage: bin2hex <input> <output> [<column-width>]*

If the input is a binary file, writes a human-readable hex contents to the output file (will overwrite if output exists).
Example: for bin2hex input.dll output.txt 8 8 the output.txt will contain

4D 5A 90 00 03 00 00 00  04 00 00 00 FF FF 00 00
B8 00 00 00 00 00 00 00  40 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00
...

By default the tool will output bytes on a single line separated by space. Specify one or more space-separated numbers after input and output to create columns.

  Example: bin2hex foo.dll foo.txt 8         - uses one 8-byte column
  Example: bin2hex foo.dll foo.txt 4 4       - uses two 4-byte columns
  Example: bin2hex foo.dll foo.txt 8 8 8     - uses three 8-byte columns

If the input is a text hex file produced by this tool (in a format like above), writes the bytes to the output as binary. In a hex file, whitespace is ignored, so the columns, line breaks etc. don't matter.
