An encryption key is a piece of data (a string of characters or digital value) used to convert plaintext into ciphertext. This process of converting data from a readable to a scrambled format is the encryption technique that can only be decoded by the authorized or intended receivers.
Encrypted message/data is unreadable to unauthorized or third-party intruders. One notable example of encrypted data exchange is your WhatsApp chat room. This popular instant messaging app offers its millions of worldwide users an end-to-end encrypted texting experience that even
WhatsApp authority cannot access.
Cyber experts implement two types of encryption keys for securing confidential organizational data and your digital privacy as well. They are:
Symmetric Key, which is private key cryptography, is used for both encrypting and decrypting the data but with the risk of potential vulnerability. The ultimate challenge lies in the management of the key and works best for a closed system.
Whereas,
Asymmetric key, also known as public key cryptography involves a pair of keys- one public key for encryption and one private key for decryption.
Among these two keys, the latter one provides enhanced security. However, the efficiency of an encryption key greatly depends on its length measured in bits. The longer key promises enhanced security.
Hashing is another method of data encryption, which generates a signature of a fixed length for a specific set of data or messages. However, the only drawback of a message with a hash is that it cannot be reversed back to the original text. Hashing is now used as the only way to confirm that the message or data has not been tampered with.
Data encryption is done to keep curious eyes from reading sensitive information while in transit. Encryption can be used to protect documents, files, messages, and any other type of network communication.
Encryption is a critical tool for maintaining the integrity of our data, and its importance cannot be emphasized. Almost everything we surf through the internet, whether company web pages or scrolling apps, has been through some level of encryption to keep breaches at bay.
For the sake of secure transmission of organizational information, cyber and security specialists convert sensitive data into an encoded or encrypted design. The purpose of network encryption is to ensure impenetrable transmission of data between server and client or server-server. The intended party or receiver must know the secret decryption key to encrypt the transmitted data.
Data is encrypted for the ultimate purpose of securing sensitive information that is exclusive to an organization or individual. As cybercrimes are crippling the dataspace, wrecking permanent damage to a company’s reputation; the importance of data encryption has intensified than ever. Enroll in an advanced course today!
Here are 4 subtle reasons that ignite the purpose of data encryption:
These are the possible reasons behind the scaling importance of data encryption only for enhanced security of your digital data.
So, let's discuss the best algorithms for encryption, among the plethora of encryption methods, we will discuss the top 6 popular algorithms in detail.
AES: The Advanced Encryption Standard (AES) is a widely applied encryption technique by the US government and other leading organizations. AES implements 192- and 256-bit keys for paramount encryption needs, besides the 128-bit version. Except for brute force, AES is widely thought to be impregnable to all attacks. Because of very few demerits, AES has been predicted to become the de facto standard for data encryption in the private sector shortly.
Triple DES: Triple DES replaced the first Data Encryption Standard (DES) algorithm, which became vulnerable to breaching. Its symmetric encryption, which was once the industry’s most extensively applied technique, is now being phased out.
RSA: RSA is an asymmetric public-key encryption technique for encrypting information shared over the internet. Since RSA encryption is hard to decode, it frustrates amateur hackers to invest a great deal of time and energy in cracking into it, creates a lot of babble, it baffles would-be programmers, driving them to invest a great deal of time and energy attempting to break into the frameworks.
Blowfish: Another algorithm aimed to replace DES is Blowfish. This symmetric utility breaks down messages into 64-bit blocks before encrypting each message individually. Blowfish are known for being quick, flexible, and unbreakable. This symmetric tool is widely used in e-commerce platforms, payment gateway, and password management.
Twofish: Blowfish’s successor is Twofish. It’s symmetric encryption that decrypts 128-bit data blocks without requiring a license. Twofish is one of the fastest of its kind and is suitable for both software and hardware contexts. This mechanism is used by many of today’s file and folder encryption software.
Rivest-Shamir-Adleman: It is an asymmetric encryption technique based on factoring the product of two large prime numbers. Only someone with access to those prime numbers can decipher the message.
Data encryption is a core aspect of cybersecurity, which is going to counter more complexities with the surface of newer cybercrime techniques.
