Base64 Tools - five little ones ;)

Update Now added a fifth "little one", Base64Convertor. This will convert a binary file to a base64 string, and convert a suitable base64 string to a binary file. You will have to set absolute paths (possibly full paths in some circumstances) to the files... You can download this extension from the first post in this topic.
