Yes, I'm aware of that format and john only need the first 2 fields to
work with, and the rest, AFAIK is ignored.

So the format from my example should be:
000000:$1$670b14728ad9902aecba32e22fa4f6bd

Googling around, I found a piece of code that could do that.

not python expert and I have a little knowledge about encryption.
