Kms Encryption Type

[Jennifer Leos]

Nowyou must be wondering what is encryption? How does it work? How many types of encryption are there? Is there any encryption standard that one can follow? What else do you require to protect your data? I will answer all of these questions for you in this article. If you are curious to know, keep reading till the end!

Encryption is considered as a secure way of transferring or sharing data to avoid third-party intervention. It can be done at any given point of the entire data flow; it is not an isolated process. You can encrypt your data while you are working at it or you are about to send it.

In simpler words, encryption uses algorithms to jumble up whatever data you want to encrypt. You need to have a randomly generated key before sending the message or data to the person at the receiving end, through which they can decrypt it. Imagine you have put a lock on the box containing important documents with the help of a key. You send that box to your friend. She has the same key as yours through which she is able to unlock it and get access to those important documents. But in the digital world, all this is done electronically!

1) Symmetric: It works on a single private key, therefore it is faster than asymmetric encryption (explained in detail in the next bullet). For symmetric encryption methods, the sender must share the private key with the receiver to access the data or information.

It is an old encryption technique that is very well known. Since the secret key is supposed to be shared with both the sender and the receiver, it becomes fairly risky for the hackers to get to the data or information.

2) Asymmetric: This encryption method works with two keys: one public key and one private key. The public key is shared with anyone. However, the private key must remain a secret key because you will encrypt your data or message using a public key and decrypt using a private key. Again imagine a situation where you have put two locks on a box that has confidential information. One of those two locks has a master key that anyone can have access to. However, the second key is only with you and a friend with whom you have to share the box. You send the box to your friend with the help of another person. He tries to open it and only get through one lock because he has the master key. With no luck, he delivers the box to your friend, who with the help of a second key can have access to the information you shared.

Since this encryption technique works on two keys, therefore any algorithm based on it will be considered the strongest encryption type because it ensures high levels of security. Until now, no one has been able to hack asymmetric key encryption.

As technology is advancing, modern encryption techniques have taken over the outdated ones. Hence, there are several different types of encryption software that have made our job easy. So for your ease, I have provided you with a list of the best encryption types and examples below.

Triple Data Encryption Algorithm or Triple-DES uses symmetric encryption. It is an advanced version of DES block cipher, which used to have a 56-bit key. However, and as the name suggests, TDES encrypts data using a 56-bit key thrice, making it a 168-bit key. It works in three phases when encrypting the data:

Since it encrypts thrice, therefore it is much slower as compared to other types of encryption. Not only that, but it also encrypts data in shorter block lengths, therefore it becomes fairly easy to decrypt the data during the entire encryption process. Hence, there is a higher risk of data theft. However, before other modified types of encryptions emerged, it was the most recommended and widely adopted algorithm.

The Advanced Encryption Standard (AES) is also symmetric encryption based on the Rijndael algorithm. It uses block cipher and encrypts one fixed-size block at a time. It works in 128-bit or 192-bit but can be extended up to the 256-bit key length. To encrypt every bit, there are different rounds. For instance, 128-bit will have 10 rounds, 192-bit will have 12 rounds and so on.

It is considered one of the best encryption algorithms because it was developed by the US National Institute of Standards and Technology. It is also one of the secured types of encryptions as it works on a single private key.

Due to its larger key size, it is known to be one of the strongest encryption types. It is also considered as an encryption standard for data shared over the encrypt internet connection because it is the most secure encryption algorithm up till now. As compared to other types of encryption, RSA gives hackers quite a tough time because of the length of the keys it works with.

Another encryption algorithm designed to replace DES, Blowfish is a symmetric block cipher, which works on a variable key length from 32 bits to 448 bits. Since it is a block cipher, therefore it divides data or a message into fixed 64-bit blocks when encrypting and decrypting.

It was designed to function fast and is available as free public encryption software for any user. It is neither patented nor licensed. Being a public encryption platform, it has been tested multiple times for its speed, efficiency and security. Many organisations claim that no one has successfully hacked it. Hence, Blowfish has become a choice for vendors and e-commerce mainly helping them secure payments, passwords and other confidential information.

Also a symmetric block cipher, Twofish is an advanced version of Blowfish encryption. It has a block size of 128-bits and can extend to the 256-bit key length. Like other symmetric ciphers, it also breaks data into fixed-length blocks. However, it functions in 16 rounds regardless of how large the data is. Amongst the various types of encryption, this one is flexible. It allows you to choose the encryption process to be quick while the key setup to be slow and vice versa.

Since this is license-free and considerable fast, you have full control over it as compared to other types of encryption. If AES would not have become the best encryption algorithm, Twofish would have been considered as one.

Format Preserving Encryption (FPE) is one of the fairly new encryption methods. It encrypts your data in a similar format. For instance, if you have encrypted your password having 6 letters, 5 numbers and 4 special letters, then your output will be a different combination of a similar format.

By this point, I am assuming you are well-aware of how to secure your data. But there is another factor that needs to be addressed, which is how to make sure that the message you send does not get altered or changed. For that, you need to know about the following encryption applications that will make sure of that.

Once you have chosen your desired encryption type, you need to further make sure that your data is not altered and is authentic and verified. For that, you need to use hashes. They are a one-way function that takes a large set of data and convert them into small standard size data. You create a unique fingerprint that is proof that your data has not been altered during different encryption levels. The outcome of hashing is called hash value or hash digest.

If by any chance there is a doubt of data being changed or altered, you can always compare the original hash with that of the new one because two differently altered data cannot produce the same hashes.

If we look at the backend process, then hash functions when a user logins through their ID and password. The server searches for the associated hash value. The password which you entered is hashed with the same algorithm through which it was encrypted. If it matches with the already stored hash value then it is valid and authenticated.

Once you have identified that your encrypted information is not altered, it is also necessary to identify from which source your encrypted information is coming and who will decrypt it. This is where digital certificates come in, which are also known as identity certificates or public-key certificates.

They authenticate the details of the sender and receiver of the encrypted data over the internet using various types of encryption methods. Any certification authority will issue you your digital certificate. It will contain the following:

In order to conduct private communication over a network, we need to make sure that our devices and our channels of communication are safe and secure. The ways in which we can achieve this are called encryption protocols.

Internet Protocol Security (IPsec) is a framework for different types of encryption. It helps verify different packets, which are encrypted and decrypted using a public and a private key, within the protocol. For authentication, hash values are also added in those packets. If the sent packet is different from the received packet, then you can easily identify that there has been a change made during the process.

1. Tunnel mode: The entire packet, including the header, is encrypted and placed in another packet. It is then forwarded to a central VPN, where the endpoints decrypt. After decryption, the packets are sent to the correct IP.

Point-to-Point Tunneling Protocol (PPTP) was developed by Microsoft and other tech companies as a framework for types of encryption. It makes sure that the communication between the VPN (Virtual Private Network) client and the VPN server is without any disturbance.

Layer 2 Tunneling Protocol, endorsed by Microsoft and Cisco, is another framework for types of encryption which is used in hardware-based encryption devices. Unlike PPTP, it encloses the network data twice making the whole process slower.

Specifically designed to connect with a Web server, Secure Sockets Layer (SSL), now known as Transport Layer Security (TLS), provides data encryption, message integrity using certificates and authentication during encryption and decryption.

Data security has become the focus of the whole internet world. It is really up to you to decide which encryption technique is better suited for you, along with the right combination of encryption application and protocols.
