SSL (secured socket layer) explained

Secured Socket Layer

This technology was developed by Netscape in the Mid 1990s. The technology has become standard in exchanging data over unsecured environment like the internet.

Since we already mentioned that SSL secured data exchange on an unsecured environment like internet, and we all know that internet is almost all about websites. SSL helps in securing your website data. Once this service is installed on your server, a padlock sign will always appear on your address. Which will change HTTP (hypertext transfer protocol) to HTTPS (Hypertext transfer protocol secured). As already mentioned this technology has become standard to almost all websites. Once this certificate is installed on your server your data is secured (don't forget that a perfect system doesn't exist but at least the attacker has to put effort to get through).

SSL uses a handshake like techniques to make sure data is secured. When client needs to access data from a saver or location that uses SSL, the server will provide digital certificate to the client. This credentials will make the user identify the server. The client make sure the domain name matches the with the CA (certificate authority this is a body that issues digital certificates. Digital certificate certifies the ownership of the public key by the named subject of the certificate). The client has to make sure the name on the certificate corresponds with the domain name (web address) and the certificate is valid.

After completion of the handshake, the client will encrypt the data and send it over the server. This is done before the data leaves the client system (smart devices or computer). As we all knew that encrypted data cant read or tempered with, unless if it comes under heavy attack. At arriving at the server end, the server has to decrypt the data to use it. If the server needs to send by data to the client, the data has to be encrypted too.

Internet without this technology will have been an untrusted place! SSL make the internet a bit secured though not fully secured!

Microsoft Office for Tablet now on Google Play store

Back in November, Microsoft opened up early previews builds for its new mobile Office applications for Android tablets to those willing to sign up and wait for an invitation. After taking on feedback over the past couple of months, Microsoft has announced that it is expanding its preview scheme by releasing its Office applications to everyone directly through the Google Play Store. The new Office software for mobile unifies Android, IOS, and Windows platforms. Previously each platform had to make do with its own apps, meaning that feature sets differed depending on your operating system and updates were often slow and intermittent. By unifying the Office platform, Microsoft hopes to bring updates and new features to users in a timelier manner. There are still a couple of conditions attached to the preview builds though. Firstly, Office is still limited to ARM-based Android tablets with a screen size between 7 and 10.1 inches. Your tablet will also need to be running Ki...

Ethical Hacking Simplified. Applications of Cryptography

Pretty good Privacy PGP This type of cryptographic Application uses Public key encryption system and  is one of the most popular means of encryption in the world. It is used in securing data, data storage, email, Instant Messaging (instant messaging are messaging system that happens in real time, just like whatsApp, Facebook messenger etc.) and other forms of communication. The early version of this cryptographic application was written by Philip Zimmerman and has it public appearance in 1991. it is part of an open-source project with many version where user can choose the best that suit them. This cryptographic application comes with privacy and security measure that are found in many online systems. The data will travel in an encrypted form (chipertext), upon arriving at the receiving end, the receiving will use PGP to decrypt the data back to plaintext. PGP uses the Public/Private key encryption. Where the sender uses his public key to encrypt data, and the receiver ...

Tips for strong password

As we have already discussed that passwords are strong and at the same time weak! If user create password from his name, date of birth or any other combination that is related to him, cracking down his account doesn't need much technical know how. Meaning attacker who know you, can be lucky enough to access your sensitive information by only entering certain key combinations. Creating strong and almost non hackable wait!!! is there any non hackable password! I was once told that any system can be hacked! It only took time, skills and resources! You are absolutely right! But at-least one has to really suffer before getting your data! Arm robbers do rob banks! Do you think a local or common thief can rob bank? The ans is absolute NO! Strong passwords doesn't happen by chance! Below are the steps to create a very strong passwords! Passwords should be at-least 8 characters Its already becoming standard on the internet. Many websites doesn't allow less than 6 charact...
