About 5 million Gmail IDs and passwords leaked

About 5 million Gmail IDs and passwords leaked

Is Google got hacked?
No, the leak was not the result of a security breach of Google systems.  The dump is said to have been obtained from other websites.
So, if you have used the same password used anywhere else, your Gmail account could be compromised.

Google's response:
"We found that less than 2% of the username and password combinations might have worked, and our automated anti-hijacking systems would have blocked many of those login attempts. We’ve protected the affected accounts and have required those users to reset their passwords." Google wrote.

What you should do?
•          There are few websites available online to check whether your Gmail ID have been compromised or not.  My suggestion is don't use them.  I suggest everyone to change the password. (I believe most of the people keep the same password for years, so it's better to change now).
•          If you have not enabled 2-step-factor feature, it is good to enable it.

•          Never use the Gmail password in any other websites.

Security Encryption Systems

Computer encryption is based on the science of cryptography, which has been used as long as humans have wanted to keep information secret. Before the digital age, the biggest users of cryptography were governments, particularly for military purposes.

The Greek historian Plutarch wrote, for example, about Spartan generals who sent and received sensitive messages using a scytale, a thin cylinder made out of wood. The general would wrap a piece of parchment around the scytale and write his message along its length. When someone removed the paper from the cylinder, the writing appeared to be a jumble of nonsense. But if the other general receiving the parchment had a scytale of similar size, he could wrap the paper around it and easily read the intended message.

The Greeks were also the first to use ciphers, specific codes that involve substitutions or transpositions of letters and numbers.
As long as both generals had the correct cipher, they could decode any message the other sent. To make the message more difficult to decipher, they could arrange the letters inside the grid in any combination.

Most forms of cryptography in use these days rely on computers, simply because a human-based code is too easy for a computer to crack. Ciphers are also better known today as algorithms, which are the guides for encryption -- they provide a way in which to craft a message and give a certain range of possible combinations.
Computer encryption systems generally belong in one of two categories:

Symmetric-key encryption
Public-key encryption
