How Passwords are stored? Explaining encryption, hash and cracking

We’ve so far discussed the login process, authorized and unauthorized access. If you’ve noticed one of the main points in all these writeups were the Passwords. So I decided to reach you out with another short writeup about the storage of passwords in certain ways. A password is an important factor to guard our digital privacy. It’s just like the key to unlocking our privacy box. Before going to…

Encryption

Encryption

In the contemporary world where the news about data leaks and security breaches have become quite frequent, cyber-security and more specifically encryption is an important concept for many companies to understand and implement. Security breaches and data leaks cost millions of dollars to organizations. IT Security has become the highest priority for many global companies and government departments.

There are many security protocols and technologies available which help organizations to secure their infrastructure, data and communications. However, encryption is one of the most important part of IT security strategies that are implemented by companies and government departments.

Encryption is a technique which helps protect the data and communications.

What is encryption?

Encryption is a technique of encoding the information in such a manner that it becomes unreadable and only authorized parties are able to access it. The authorized party can access the information using a key which decodes the information.

The encrypting process basically transforms the information or a message from plain text to cipher text by encrypting it using an encryption algorithm. The cipher text can only be read when it is decrypted using a key, which only the authorized party will have. Encryption ensures that data is not read or altered by unauthorized parties.

Here is an example of how encryption works.

When you send an email using an encrypted email service, the plain text message is scrambled and made unreadable for unauthorized parties.

This is how an encrypted email message looks like:

Only the intended authorized recipient can decrypt the above encrypted text. The authorized party receives a private key from the sender of the email, using this private the authorized recipient can decrypt the email.

Decrypted email text:

"Hello John, How are you doing? Join me for a cup of coffee next week in San Francisco. Best, Alex."

Different Encryption Methods

Symmetric Encryption:

Symmetric Encryption, also known as private-key cryptography, uses a single key for encryption and decryption. The sender encrypts the data with a private-key, sends the encrypted data to the authorized recipient, the recipient uses the same private-key to decrypt the data. Symmetric Encryption is also known as private-key or secret-key cryptography because it uses a secure private-key for both encrypting and decrypting processes.

Asymmetric Encryption:

Asymmetric Encryption, also known as public-key cryptography, uses two different keys for encryption and decryption and hence differs from symmetric method. In asymmetric method, a public-key is used for encrypting process whereas a private-key is used for decrypting process.

Hashing:

Hashing is a type of cryptographic security which generates a unique fixed-length value or a hash for a message or data. Hashing is irreversible, once a message is condensed into an irreversible fixed-length value, it cannot be reversed. This is where hashing differs from encryption which is a two step process where a message is first encrypted and then decrypted, which is not the case with hashing. Hashing is a single step irreversible process.

Hashing is used to verify the data and check if the data has been tampered with, and cannot retrieve the original message.

Encryption is the last and strongest line of defense against the myriad attacks your computer experiences every day. Spam filters, Firewalls, Privacy Settings, Passwords and Anti-virus programs all offer defensive measures against broad based attacks, but none of these offer any defense against targeted data theft.

How Encryption works in PGP software

Despite from its humorous name Pretty Good Privacy, (PGP) encryption  is the most powerful encryption software in the cryptology industry. PGP is used commercially by most email providers and many computer users are using this for securing the confidential information over internet. Well, it is pretty good that we have such an extent by which we certainly can able to code the precise information without allowing others to read the information without having its key, or knowledge of the code.

Well, PGP software’s functionalities are completely relies on encryption standard, even more than of that supporting various other flexibilities such as allows encrypt and digital sign files, emails and instant messages and supports secure text editor, secure file deletion, secure zip archives, secure file deletion and many more other functionalities which are certainly worth for securing confidential information from others.

Well, PGP software is created by Phillip Zimmerman in 1991 and it follows the Open PGP standard for the encryption and decryption of data. Phillip Zimmerman has created this based on this concept of public-key cryptography for binding information to a username or any email address to send encrypted data securely through the Internet and decrypted when it reaches to its destination. So this is what PGP software all does for securing the information to being theft.

Well, as it said, encryption is the process of encoding messages and while it is encrypted it is hard to read them to get the information if one has no knowledge about its public-key cryptography. So even if your data is being hacked in between the communication and reaches to hacker instead of the destination, then the person who gets this can unable to read it at any way. So this is how PGP software can ensure you for securing your confidential information over internet.
