But once after creating the iso file i would want to edit it. Because i want to find the md5sum of the ISO file, and store it there.
You appear to not understand the point of doing a md5sum hash of the image after it is created. If you change anything about the ISO image after you have hashed it, then by definition the hash is incorrect and useless for checking the integrity of the image.

You have to store the md5sum hash somewhere outside of the ISO file.
