A screenshot for my favorite hex editor, HxD.

• Copy as string literal "\x12\x34\x56\x78"
• Copy as Python array [0x12, 0x34, 0x56, 0x78]
• To/from Base64

Based off the example by the HxD author

Unfortunately, the selection size is limited to 0x1000 for performance reasons.

Download from releases and add to C:\Program Files\HxD\Plugins. Create the folder if it doesn't already exist

This is only supported on HxD 2.4.0.0 but it will still work on other versions.

Compile the solution in Examples\C++ with VS2019
