Ever wondered What is encryption technology? And how encryption technology works? Or What is end to end encryption?

Nowadays as the technology is growing, it makes us wonder more .Some of the technologies are easy to understand but many terms related to them are not easily understandable by common people which makes them easy to be fooled by others or confused.

 

 Encryption and how it works?

 Encryption is a term that we often see or heard of many times like: google - encryption , whatsapp - end to end encryption , and yahoo encryption. All of them say that your data is encrypted so, you need not to worry.


Search engines collect and pass a lot of data reguraly, so to protect their costumers data the use of encryption comes into play.

What is encryption?

 In cryptography,

encryption is the method of encoding valuable data which was present in a coded format manner, 

this process works by converting the original  form of the information, known as plaintext, into an alternative form called as ciphertext.

Only authorized parties can convert back a ciphertext back to plaintext and access the original information.

 Or in more easy way, you may think encryption as storing any information or data in a code format which can be only be solved and converted in easy to understand format by the allowed parties only.

Encryption uses an algorithm for encrypting the informational data and then uses an unlock key for the receiving person to decrypting the data.

algorithm

 An encryption scheme generally uses a pseudo-random-encryption key which is produced by an algorithm. It may be possible to decrypt the information without having the key, but it requires high computational resources and skills for breaking a well-designed encryption 

How does Encryption really work?

As described above encryption uses algorithms to encrypt your data. It us then send to the receiving party/person, who's system is provided with a key to decode the message. There are algorithms of different types, and they involve different methods for encrypting and then decrypting the data.

Any allowed party can easily decode the data with the key provided by the creator to the person's system but not to unauthorized agents.In the past, various encryptions have been used to giving an aid in cryptography. In the old days,the encryption techniques were commonly used in military for end to end encryption for transmitting and receiving messages. 



Since then, many advanced technology have came out and become generally used things in all areas of computer security. New encryption techniques uses the concepts of public-key and symmetric-key.New encoding ways guarantee security as a result of trendy computers square measure inefficient at cracking the encoding.

Researchers at NIST and some other cybersecurity experts had suggested that the development of quantum computers might harm the current encryption systems.

Data encryption

How the key to encryption is generated?

  Key generation is described as a process of generating keys for cryptography purpose. The generated key is then used in encrypting and decrypting process.

New cryptographic system includes symmetric-key algorithms ( like as DES and AES) and public-key algorithms ( like as RSA). 

1. Symmetric-key algorithm uses a single shared key, thus keeping data to secret level requires to keep the key secret. 

2. Public-key algorithms includes a public key and a private key. The public key is available to anyone (generally through of a digital certificate). A owner will encrypt information with a specific public key, then only the person or party with the private key can decrypt this data. 

 

cryptography keys are nothing but integers. In general cases, keys are randomly created using a random number generator (RNG) or pseudorandom number generator (PRNG), then the latter being an algorithm that produces information which appears as random under analysis. 



Few types of the PRNGs algorithms uses the system entropy to create a seed information, such seeds then produces the better results, since this makes the initial conditions of the PRNG more difficult for a hacker to guess.





In other conditions, the key is created using a passphrase and a key generation algorithm, using a cryptographic hash function such as SHA-1. 

What is Encryption Algorithm? 

 

Encryption algorithm is more of a mathematical process to perform encryption on provided information.The algorithms plays a major role of transforming any simple text or data into an encrypted document, and then transforming that encrypted data to readable format.



The encryption algorithms thus, by converting simple information into a coded format, prevents hackers and any other unauthorized parties to gain access to the transmitted data.

 What are some commonly used Encryption Algorithms?

 

There are present a number of encryption algorithms, thus performing in a different ways for different purposes.


The most commonly used encryption algorithms are - RSA, 3DES, and AES.

1. RSA or (Rivest Shamir Adleman) is AN uneven coding formula used in trendy computing for encrypting and decrypting the transmitted datas.

Asymmetric cryptography refers to cryptography having a pair of fully completely different keys, to boot called as public key cryptography, because of the actual fact that one in each of the keys is given to a person or party.The opposite key has to be unbroken personal to remain the information secure.

This formula relies on the princple that to seek out the factors of a bigger number is extremely hard- once the factors square measure prime numbers, the matter is named prime factorisation.It's to boot a key strive (public and private key) generator.

2. 3DES - In cryptography, Triple DES (3DES or TDES), formally the Triple encryption algorithmic program (TDEA or Triple DEA), may be a symmetric-key block cipher, that applies the DES cipher algorithmic program thrice to every information block.

The information secret writing Standard's (DES) 56-bit secret is now not thought of adequate within the face of contemporary cryptologic techniques and supercomputing power. However, associate degree tailored version of DES, Triple DES (3DES), uses a similar algorithmic program to supply a safer secret writing.






While the govt and business standards abbreviate the algorithm's name as TDES (Triple DES) and TDEA (Triple encryption Algorithm), RFC 1851 remarked it as 3DES from the time it 1st published the thought, and this someone has since acquire wide use by most vendors, users, and cryptographers.

3.AES - The Advanced Encryption Standard (AES),additionally better-known by its original name Rijndael, may be a specification for the cryptography of electronic knowledge established by the U.S. (NIST).



The formula delineate by AES could be a symmetric-key formula, which means identical key's used for each encrypting and decrypting the information.

Why is data encryption necessary? 

 

 

Encryption, is that the method of fixing data in such some way on create it unclear by anyone except those possessing special information (usually cited as a "key") that permits them to alter the data back to its original, decipherable type.

Encryption is vital as a result of it permits you to firmly defend information that you just don't desire anyone else to possess access to. Businesses use it to guard company secrets, governments use it to secure classified info, and lots of people use it to guard personal info to protect against things like fraud.

Espionage uses secret writing to firmly defend folder contents, that may contain emails, chat histories, tax data, mastercard numbers, or the other sensitive data. This way, although your computer is purloined that information is safe.

 

What is a brute force attack in encryption?

 

 A brute-force attack includes a degree wrongdoer submitting many passwords or passphrases with the hope of eventually shot properly.
The bad person systematically checks all potential passwords and passphrases until the proper one is found or else, the bad person can decide to guess the key that's usually created from the payrole using a key derivation operate.

 This can be noted as associate degree thoroughgoing key search.

A brute-force attack could be a science attack that may, in theory, be accustomed decide to rewrite associate degreey encrypted information (except for data encrypted in an information-theoretically secure manner). 

Such associate degree attack may be used once it's impossible to require advantage of different weaknesses in associate degree cryptography system (if any exist) that may create the task easier.
