  GO AHEAD, SELL MY DATA

More and more I see articles popping up that bash social networks for "violating" our privacy and selling our information to advertisers. Inevitably, Facebook has been at the center of many of these "scandals". Today on HN I came across this interviewwith Disconnect co-founder Casey Oppenheim and I just don't get it.In it, he bashes Facebook (and other online advertisers) for using our information in order to serve up targeted ads. He points out that many of the " “free” service...

  Backend-as-a-service?

As the list of *-as-a-service’s continues to grow, I thought I’d throw one into the mix. What about the idea of a backend-as-a-service (BaaS)? The recent surge of client side Javascript frameworks along with the attractiveness of simple RESTful APIs has created an environment where server-side interaction can be reduced to simply database interaction (including validation and some computation). But why stop there? What if the server-side of the equation was simply a RESTful, ...

  bcrypt: Safeguarding Passwords with Strong Hashing and Adaptive Security

Introduction In today's digital world, passwords play a crucial role in protecting personal privacy and information security. Passwords are the most commonly used means of authentication because they are simple yet effective. Password security is the cornerstone of cybersecurity and plays a fundamental role in safeguarding the information security of individuals and organizations. However, with the increasing frequency and complexity of cyberattacks, traditional password hashing algorithms like ...

  SSH Security and You - /bin/false is *not* security

Backstory While at RIT around 2004 or 2005, I discovered that a few important machines at the datacenter allowed all students, faculty, and staff to authenticate against them via ssh. Everyone's shells appear to be set to /bin/false (or some derivative) on said machines, so the only thing you'll see after you authenticate is the login banner and your connection will close. I thought to myself, "Fine, no shell for me. I wonder if port forwarding works?" ...

  Using public key authentication in SSH

SSH is a popular cryptographic network protocol for secure network service operation. It is frequently used in remote server login. For a system administrator or software developer, SSH is frequently used to access remote servers or development servers or testing servers etc.  To login with SSH, there are different authentication mechanisms : password, public key and interactive etc. If a remote server needs to be accessed frequently, password authentication may be too troublesome as p...

  A HTTPS client and HTTPS server demo in Java

In this post, I will create a HTTPS server and HTTPS client demo which can establish HTTPS communication between a server and a client using Java. This should be very useful when we want to test our understanding about SSL communication. We will use both a detailed SSL client and a simple HttpsURLConnection as the HTTPS client. Before creating the actual HTTPS server and HTTPS client, we first need to generate the keystore and truststore to be used by the server and client. To generate the keyst...

  Implementing DESede/ECB/NoPadding cipher algorithm in GoLang

By default, GoLang doesn't provide the ECB mode cipher for DESede though there is CBC mode provided. In cases we need to encrypt/decrypt data with ECB mode, we need to implement those by ourselves. This mode is frequently used when encrypting/decrypting PIN block which is small block data less than 16 bytes. In this post, we will introduce how to implement the DESede/ECB/NoPadding algorithm in GoLang by using the existing cipher support. Here we will not cover how DESede works in detail, instead...

  Generate certificate from cert file in Java

A certificate is often used to prove the identity of a server. The certificate will contain information such as the subject and issuer of the certificate. It will also contain the validation date of the certificate. A certificate is often exported to an external cert file which is transferred over the internet. We will often see its use in SSL communication which provides secure communication between two entities. In this post, we will show how to read the data from an external certificate file ...
