Patrick’s development blog

About me

My name is Patrick and i’m 20 years old. I’m a hobby developer who has been making programs and websites for a couple of years now. I currently study computer science in Sweden. I’ve decided to start a blog so I have somewhere to write my thoughts. It’s a sort of collection of things i’ve come across, so I don’t have to search the whole WWW in order to refind the problems.

If someone spots any errors in my posts. I would be glad if you pointed it out since i’m also writing to learn new things and I want to keep things as correct as possible.

    Hi Patrick,
    Thanks for the blogs on security, they are quite helpful to me.
    I have a question that I wonder if you can help, or any pointer will be appreciated.
    It’s about key management or key change in PKI. For example, I have key pair key-A
    that I used to encrypt my one million data records. Now, the key-A pair expired, and
    I renewed the key pair, now become key-B. Do I really have to decrypt all one million
    data records with key-A (before it expire) and re-encrypt all one million data records
    with key-B (for the valid PKI certf)? that would be insane. There got to have some
    better way of managing this key change in PKI system!

    Sorry James I can’t help you with that. I don’t think you can decrypt it with another key though.
