A lot of users search for Cryptography, they want to know What is Cryptography. So, we have brought this article to clear your doubts about cryptography.
In this article, we will see about Cryptography and it working mechanism. Let’s start our article without wasting time.
What is Cryptography?
Cryptography is used for information and communication security, it also maintains the privacy of data of the users. In cryptography service, data is encrypted using a certain algorithm. The plain text is converted into a ciphertext where ciphertext is considered as encrypted text.
The word Cryptography is derived from the Greek word. kryptós means hidden or secret whereas graphein means to write.
We can take the example of WhatsApp. WhatsApp uses 256-bit encryption to make the message secure. In case of any data breaching, attackers will not get the exact message, they will get the message in encrypted form which is impossible to decrypt. In this way, all the message send through WhatsApp is end-to-end encrypted and safe.
This was the brief introduction of Cryptography with an example. You have got the answer to the question What is Cryptography. Now, we will see some terms related to cryptography. It will help you in understanding this topic easily.
What is Public Key Cryptography?
Public Key Cryptography is also known as Asymmetric Cryptography. In this Cryptography, there are two types of keys. One is Public key while other is Private key. The public key can be shared or distributed to another person. In the case of Private key, never share it with anyone. The pubic key is used for encryption while we use the Private key for decryption.
Till now, we know what is cryptography, what is public key cryptography. Now, it is time to get the answer to the question what is quantum cryptography?
What is Quantum Cryptography?
Quantum Cryptography is also known as Quantum Encryption. In this encryption, message is encrypted using the principles of Quantum mechanics. Due to this, the message cannot be read by any outsider except sender and receiver.
We hope that you have understand Quantum Cryptography. Now, we will see what is fips cryptography?
What is FIPS Cryptography?
FIPS Cryptography is one of the most popular Cryptography. Many companies use this method to make their data of Computing devices and telecommunication systems safe.
There are many standards of FIPS such as FPIS-1, FIPS-2, and much more.
What is the need for Cryptography?
Many people think that what is the need for Cryptography? Cannot we live without encryption? We will give answers to all your questions.
Actually, we need Cryptography because it makes our network and message safe. Without this encryption, attackers can steal your important data. If you are sharing any confidential data with someone on an encrypted network, attackers will not get your data at any cost. Due to this, you will become safe.
That’s all for this article, we hope that you have got the answer to your question What is cryptography.
Conclusion: What is Cryptography?
