ob-base64

Decode and interpret base64 as images, binary (hexl) or raw (plaintext possibly).

How to

Install it from Melpa or clone and install manually, then:

1. Have org-mode enabled in a buffer and create a source block
2. Check example.org or documentation for org-babel-execute:base64
3. Execute the block with C-c C-c

Customization

By default the rendering is set to happen internally, with an option to use an external viewer (such as xviewer) and can be changed to any other binary.

Make sure to check related defconst parts of the file to customize or the ob-base64 customize group.
