What is cryptography- Let us know about the major types and techniques?

Every little bit of data received and stored is essential in today’s world. Using the boom of digitization, the communication process is becoming secure and tighter. Transmitting sensitive information through a communication channel requires a large amount of security. A lot of people use data encryption methodology to safeguard their information. However, when an individual learns what is cryptography and the benefits are, they'd start following this technology.

  • The information needs to be protected from end-to-end because of the following reasons.
  • There are a lot of unethical hackers who'd steal the data.
  • The information that you are sending has to reach the proper only use.
  • The confidentiality of the information is intact well if you find proper protection.

Using encryption, you can secure data, only one cannot check user authentication. Therefore, understanding what is cryptography has become highly essential. Let us quickly understand the details of Crypto and the types of cryptography that people may use to guard the information.

What is Cryptography?

The conversion of plain text files into incomprehensible text files or vice-versa is known as Cryptography. You can process messages or even the information and read them by the proper receivers only. Using the using Crypto, the reader/receiver can easily get the authentication of the sender as well.

Crypto is totally levels over the other kinds of encryption techniques that are utilized to protect the data. Initially, It was also known by the name encryption. But, using the advancement and technology, the concept has its own identification. The process of cryptography largely uses the theories and ideas from Mathematics and Computer science to secure the information.

Advantages of utilizing cryptography

  • The information is highly safe and confidential. No one but the intended user would be able to decode the message completely.
  • Altering the data has zero scopes when cryptography can be used.
  • The intentions from the sender can be simply tracked with the help of cryptography. It's a Non-repudiation.
  • Both the senders and the receivers can confirm the authenticity of the messages and their identification.

After understanding the merits of Cryptography, it becomes essential to also understand the places where this technology can be used.

  • Usage of cryptography in places like Banks along with other financial institutions are pretty common. The passwords of the an atm card, credit cards, and then any other transactions within the banks utilize this technology vastly.
  • A lot of e-commerce websites also use Cryptography techniques to keep their data safe and secure.
  • Computer passwords also employ Cryptography. Cryptography is largely being used to protect data that are totally confidential.
  • In almost all the electronic transactions, you can use the Cryptography techniques.

types of cryptography

Knowing what is cryptography isn’t sufficient enough. Only if you realize the types of cryptography, you'd be able to use them in an appropriate manner. There are three main cryptography techniques that you can use, and they're the following:

Symmetric-key cryptography

In this kind of cryptography technique, both the sender and the receiver has access to a single key. This key sharing happens between these two people throughout the exchange from the data. The messages in the sender would be encrypted and transmitted using this key.

At the receiver's end, the messages are decoded utilizing the same key to obtain the plain text. Thus, with one secret key, the transmission and sharing from the message happen between your sender and the receiver without much complications or lengthy procedures.

Public-Key Cryptography

The Public Key Cryptography is one of the concepts that individuals use largely over the last 300-400 years. Unlike the Symmetry technique, the Public-Key Cryptography uses two keys; Public and private Key. The Public Secret is in the place freely between your transmitters and the receivers. The non-public key a pair of the public key, and that remains secret totally. Just with the usage of the general public key, the users could encrypt and decrypt the messages. Public-Key Cryptography is most likely probably the most revolutionary concepts in the current generation.

Hash Functions

This algorithm uses no key whatsoever, and this is totally different from the other two techniques. This method uses the most secure way to encode a message. It can be done while using hash value according to the plain text. The hash values are constant depending on the information present in the plain text. No-one can recover the messages that are encrypted while using Hash function. The majority of the Os's make use of this method to secure passwords.

These would be the three main types of Cryptography techniques, and you may use them based on the security required. In today’s world, currencies also utilize this technique. Cryptocurrencies are trending nowadays, which is the way forward for this generation. This method ensures the safe transaction process of these digital money transactions that occur between your users.

Facts that you need to know

You cannot use Cryptography everywhere. Also, just by gathering info on what's cryptography, applying it everywhere doesn't seem possible. There are a lot of other activities that one must realize before using this method.

  • Knowing why there is data encryption has to be clear.
  • Understanding the concepts from the cryptography techniques thoroughly is mandatory.
  • Possessing knowledge on the Three States of Data and also the lifecycle of the information is needed you to use the techniques appropriately
  • Understanding the real need for data encryption along with the fundamentals would also be helpful when you plan to use Crypto
  • Along with all of these things, it is also essential to understand the limitations of this technology even before utilizing it.

We have listed exactly what one has have to know about Crypto and also the techniques. With this information, you would be capable of getting a fundamental concept of fraxel treatments. Because this generation will largely utilize this technique, it might be mandatory to know a few fundamental reasons for it. We hope this write-up on Crypto would help you to definitely relate those activities that you are already doing without being aware of this technology.
