Are you the user of SSL Certificate Indonesia? If you say that you just had a plan to install an SSL Certificate, it means that you still need to learn more about that digital certificate. SSL Certificate installation involves encryption technology, so you must also know how encryption works in securing digital data.
When you seek the best digital certificate for your website, don’t focus solely on SSL Certificate cost. There are many important things to consider in order to get the right certificate including the security level your website needs which depends on level of encryption. So, what should you know about data encryption to ensure you know how SSL Certificate secures your website?
Definition of Data Encryption
Data encryption is a security method where information is encoded and can only be accessed or decrypted by a user with a correct encryption key. Encrypted data is known as ciphertext while unencrypted data is called plaintext. Encryption is used by many organizations since it is known as one of the most popular and effective methods of data security. Two main types of data encryption are symmetric encryption and asymmetric encryption (also known as public-key encryption).
Primary Function of Data Encryption
Protecting data which is stored on a computer system and transmitted using the Internet or other networks of computer is the main purpose of data encryption. Modern encryption algorithms have replaced the outdated Data Encryption Standard (DES). That algorithm plays an important role in the security of communication and IT system. It provides and drives key security initiatives including authentication, integrity, and non-repudiation. Authentication verifies the origin of a message while integrity provides proof the contents of the message don’t get changed since it’s sent. Additionally, non-repudiation makes sure that the message sender can’t deny sending the message.
Data Encryption Process
The encryption algorithm and encryption key encrypt data or plain text. The result of the encryption process is ciphertext which is only able to view in its original form. People who want to view that data must decrypt it using the correct key. Symmetric ciphers use the same secret key to both encrypt and decrypt files or messages. Nowadays, most data encryption services adapt and use an asymmetric algorithm to exchange secret keys after using a symmetric algorithm for the data encryption process.
Asymmetric cryptography uses public key and private key. A public key is shared with everyone while the private key gets protected. RSA algorithm is a cryptosystem for public-key encryption used to secure sensitive data when it’s sent over the Internet or another insecure network. RSA stands for Rivest-Shamir-Adleman and it starts to get popularity since both public and private keys are used to encrypt the message in order to ensure confidentiality, integrity, authenticity, and non-reputability of electronic communication and data through the digital signature usage.
Data Encryption Solution
Data encryption can provide a solution for devices, email, and data itself. Organizations or companies face the challenge when protecting data and prevent data loss. However, no one can stop employees to use external devices, removable media, and web applications. A company can’t control and protect employees from copying data to a removable device or upload it to the cloud. This is the reason why companies use data encryption solutions.
Since companies decide to provide products and services online, they also have the challenge to protect sensitive data of website visitors and customers. Sensitive data protection impacts online reputation due to the trust of customers and visitors. With more internet users trust data security you provide, your business has more chance to increase sales.
