• Security: How does a crypter actually work?

    I'm studying to become a security expert and I've recently come across the idea of a "crypter". I'm talking about how these crypters encrypt files (such as viruses and keyloggers) so they can bypass antivirus detection. But I'm curious on how they actually work. Can someone help me with a brief...

  • Why does encryption take longer than decryption?

    Why does it take longer for a system to process encryption than decryption? That seems to be the case from my experience using AES. I would think the act of decrypting files would take much longer.

  • Can I use off-the-record style encryption for my emails?

    I'm new to the security world but I know that instant messaging uses "off-the-record" encryption (which means that a user would get authentication, encryption and forward deniability). But for my email, all we use is GPG/PGP, which offers authentication and encryption but doesn't allow forward...

  • Encryption: Using a static IV

    A part of our team has had to extend our website to try to communicate user credentials for a suppliers website. We're using a 256-bit key but they're using a static IV for decrypting the information. We've advised them not to use static because it's an a security risk. But we want to know how big...

  • Why use 256 bit encryption instead of 128 bit?

    Why is that 256 bit encryption has become so popular? Isn't 128 bit security enough for most applications?

  • Intercepting two-factor authentication (SMS)

    I'm trying to learn more about "IT Security" and I've come across two-factor authentication. I understand two-factor authentication mechanisms use SMS to deliver single-use passphrase to the user. But how secure is it? Is it hard to intercept the SMS message containing the passphrase? Do mobile...

  • Password encryption: WEP, WPA and WPA2

    I'm pretty much a beginner when it comes to security but I do know that there are pretty much three different methods when it comes to Wi-Fi security: WEP, WPA and WPA2. My question is this: Does one method have better "strength" when it comes password encryption? Or are they pretty much all the...

  • Would versioning a file make it less secure?

    I'm using KeePassX as a password manager, and I've stored a KDB file in a Sparkleshare folder to back it up / sync with other devices.But just as a question (with the file being encrypted) if someone stole the file, they would several different versions of the file with minor variations. Would that...

  • S/MIME and PGP: How do they differ?

    This is more of a general question but is S/MIME an abstracted system for MIME type encryption (Just as PGP is used more for email)? Why should I choose one over the other? Is it possible both could be used at the same time?
