IS THERE ANY WAY TO EDIT THE CONTENTS OF A ZIP FILE WITHOUT LOOSING THE SIGNATURE OF IT.


Firstly HI to everyone.
Im totally new to this forum and this is my first post. So, sorry if this is violating any forum rules. And again sorry if this is not the right place to post.




Ok, coming to the point.
I had with me a zip file (of memory 15MB) signed by a company. Dam sure it is impossible to get the signature of it. I wanted to just replace a file inside the zip file. It was just 3MB. But this has to be done without loosing the signature. The signature is primary importance actually. Is there any chance (atleast 1%), so that i can replace the content without loosing the signature. And the zip file is not password protected. It is only signature protected. I can extract the contents of that zip file using winrar. But i cant edit the embedded contents of the zip file (without loosing signature) using winrar (and that is what signature is meant for).

PLS tell me if there is any chance that i can do this.
Thanks in advance. Any help is greatly appreciated.

This sounds very suspicious. If you want to replace the file then talk to the company about it. Other wise it sounds to me you are trying to disguise something. :)

I understand it is suspicious. But it is not for bad purposes. The problem is related to rooting android, the way the bootloaders are locked with encrypted signatures. They never let us to own our devices. They just think it of business and let us access to nothing, even our own hardware.


Anyhow, i think it must be impossible. But making a try just like that. Sorry mod if it is against rules.

Yep this is where it becomes a issue since they do not want their employees having access to those parts then it would be something they would have to help you with.
We cannot assist in what is basically a security measure put in place by your company and by passing it.

OK thanks. Then this thread might be useless. Pls do close it.

Atleast i understood that it is not impossible. But has bigger issues. That's ok.
