How does Symmetric Encryption Works?<\/h2>\n\n\n\n![\"Symmetric](\"https:\/\/cheapsslweb.com\/blog\/wp-content\/uploads\/2022\/10\/symmetric-encryption.webp\")
<\/figure>\n\n\n\nSymmetric encryption either uses a stream cipher or block cipher<\/a> for the encryption and decryption of data. A stream cipher converts plain text into ciphertext using one byte of data at a time. Whereas block data converts the entire unit of plaintext leveraging a predetermined key length of 128, 192, or 256 bits encryption strength<\/a>.<\/p>\n\n\n\nThe symmetric encryption process starts by encrypting the plain text into cipher text using a secret key. The data is transferred to its destination once it is encrypted. Then the sender shares its secret key with the recipient, where they decrypt the data back to its original plain text form using a similar secret key.<\/p>\n\n\n\n
Symmetric Encryption Examples<\/h2>\n\n\n\n
The symmetric encryption technique is used worldwide for data security and transportation. Here are a few popular processes that use this technique:<\/strong><\/p>\n\n\n\nAdvanced Encryption Standard (AES)<\/h3>\n\n\n\n
AES encryption<\/a> is one of the most common encryption standards mostly used in internet networks. It uses block ciphers of 128<\/a>, 192, or 256 bits<\/a> to encrypt and decrypt the data. The encryption procedure of AES is so complex that it is nearly impossible to crack this technique. <\/p>\n\n\n\nData Encryption Standard (DES)<\/h3>\n\n\n\n
DES<\/a>, or now the National Institute of Standards and Technology (NIST) is one of the oldest encryption algorithms. The algorithm breaks down the data to create 64-bit blocks. However, considering the current technology, it is easier to break this encryption method and hence is used by only a few private networks.<\/p>\n\n\n\nAlso Read:<\/strong> DES vs AES Difference<\/a><\/p>\n\n\n\nTransport Layer Security or SSL<\/h3>\n\n\n\n
You might have heard the term TLS\/SSL many times in your browser. It is a network protocol used to build a secure connection with the server-side. When a user accesses a server, symmetric keys are generated to encrypt and decrypt the data. So that it can be securely shared between the client and the server<\/a> in that particular session.<\/p>\n\n\n\nInternational Data Encryption Algorithm (IDEA)<\/h3>\n\n\n\n
IDEA is an open and free block-cipher algorithm which was first introduced in the 90\u2019s as a replacement to DES. However, as AES came into existence and turned out to be more efficient, IDEA did not succeed much and remained useful only for research and unofficial purposes.<\/p>\n\n\n\n
Benefits of Symmetric Cryptography<\/h2>\n\n\n\n
Here are some advantages of using symmetric encryption:<\/p>\n\n\n\n
Swift Processing<\/h3>\n\n\n\n
The symmetric encryption technique uses shorter key lengths as compared to asymmetric encryption, so they are much faster to execute.<\/p>\n\n\n\n
Higher Security<\/h3>\n\n\n\n
Symmetric encryption algorithms such as AES are highly secure and nearly impossible to crack.<\/p>\n\n\n\n
Ability to Process Large Files<\/h3>\n\n\n\n
One of the significant benefits of symmetric encryption is that it can work with large-size files more easily and faster.<\/p>\n\n\n\n
Disadvantages of Symmetric Encryption<\/h2>\n\n\n\n
Here are a few demerits of symmetric encryption:<\/p>\n\n\n\n
No Secure Method for Key Distribution<\/h3>\n\n\n\n
In this method, an insecure channel compromises the security of the process by transmitting the keys.<\/p>\n\n\n\n
No Digital Signatures<\/h3>\n\n\n\n
Digital signatures ensure that the message comes from a secure source. Unfortunately, symmetric encryption does not have any method for enabling digital signatures.<\/p>\n\n\n\n
What is Asymmetric Encryption?<\/h2>\n\n\n\n
Contrary to symmetric encryption, asymmetric encryption<\/a> is a process in which the data is encrypted using one key and decrypted using another. So the process involves the usage of two keys.<\/p>\n\n\n\nIt is also known as public-key cryptography. This form of encryption is more secure than symmetric encryption. However, you need to remember two sets of keys for the right implementation of this technique.<\/p>\n\n\n\n

<\/figure>\n\n\n\nCompared to symmetric encryption, asymmetric encryption technique requires two sets of keys for the entire process. This technique involves the use of both private key and public key<\/a>.<\/p>\n\n\n\nThe sender converts the plain text into cipher text using public key cryptography. After the data reaches its destination, the receiver decrypts the same data file using his private keys. The data is brought back to its original plain text form without theft of any information.<\/p>\n\n\n\n
Asymmetric Encryption Examples<\/h2>\n\n\n\n
Following are some of the examples of this encryption technique:<\/p>\n\n\n\n
Rivest Shamir Adleman (RSA)<\/h3>\n\n\n\n
RSA<\/a> is one of the most prominent examples of this encryption technique. It generates a public key for the encryption part by multiplying two large-sized, random prime numbers together. It also generates the private key needed for decrypting the data from the same prime numbers.<\/p>\n\n\n\nDigital Signature Standard (DSS)<\/h3>\n\n\n\n
Mostly used for digital signatures, people usually combine DSS with Digital Signature Algorithm (DSA). The sender uses their private key to sign a message digitally, and the receiver uses the sender\u2019s corresponding public key to acknowledge that signature and receive the encrypted file.<\/p>\n\n\n\n

Elliptic Curve Cryptography (ECC)<\/a> is an alternative to RSA that uses a small size of key mathematical elliptic curves for the process of data encryption. This algorithm technique is hugely popular because of its use in cryptocurrency. In general, ECC is much faster than RSA<\/a>.<\/p>\n\n\n\nThe Diffie-Hellman Exchange Method<\/h3>\n\n\n\n
This method is extremely vital in the history of encryption. It is a key exchange method where the two parties can share their keys with each other without physical interaction. Prior to this method, the sender and the receiver had to meet to exchange the keys with one another physically.<\/p>\n\n\n\n
