    I am trying to do outside projects during college as part of self-learning, and trying to boost my resume/portfolio for internships. Recently I taught myself how to modify the temple run apk to give myself unlimited coins, but in doing so i had to resign the apk with my own certificate.

    If i wanted to post this online, and possibly write up a blog post about it, would it be legal? I assume it would be legal if i just wanted to talk about it and how i did it, but is posting the file okay too?

    Unlikely. It will depend on whether or not the author has licensed it with a license that allows distribution of derivative works (e.g. the GPL, or a Creative Commons license). If it doesn't say so on the apps page, then you should assume not, and contact the author for permission.

    I am compiling some documents on a proof of concept. I want to find an authority that could store a document and certify in the future that:

    • I am the author of said document.
    • The date at which the document was uploaded has not been tampered with.
    • The document remained unchanged since.

    Is there a website that can act as such an authority?

    Try some timestamping services online. They'll digitally sign a timestamp. You get both free and paid for services. To get you started, have a look at these:

    For more info, read the wikipedia article on the subject. You'll have to choose a service that answers to your needs. (that will depend on a lot of factors that only you will know)
