Online businesses are constantly under pressure to create safe conditions for their customers. These businesses find solace in encryption methods that ensure better safety to their intellectual property.
Encryption means to take the data or text to be used and convert it into code with the access rights given only to authorized users. Those who don’t have a key can’t understand the information. It is quite useful for protecting the movies from getting leaked or for keeping the financial transactions secured.
Basis of classifying the online encryption methods
Online encryption methods differ on two grounds – the quantity of data possible to handle and the kind of key required to decrypt the data.
In some cases, the industrial standards form the basis of the type of online encryption to be implemented.
Main types of online encryption
Types of online encryption available are – AES, RSA, and DES. These are the basic encryption modes, which now have either undergone transformation or have become obsolete.
AES Encryption: It is one of the most robust encryption solutions that governments and businesses who deal in classified information employ for their data security purposes. This encryption method employs symmetrical key encryption. The user end requires the same key as the sender’s to decode the data protected through this encryption method.
Depending upon the number of blocks encrypted, this method is classified as:
AES-128: This encryption works on a block of 128-bit size
AES-256: A 256-bit sized block encryption is possible to achieve with this option
AES-192: The users can block a 192-bit size block
DES encryption: Though obsolete now, this encryption method was available in the 1970s. It could encrypt only 56 bits of data. Hackers found it very easy to decode. Further, the decoding process becomes lengthier too.
The newer version of this encryption is 3DES. It takes longer to encrypt using this method as the process involves triple encryption. Banks and some businesses still employ this encryption, but they are most likely to switch to more sophisticated options due to the hassles of use.
RSA encryption: The expanded form of this encryption is Reverse-Shamir-Adelman or RSA. In this encryption, a public key is created for data protection. The recipient is given a private key to decode. Thus, the process is asymmetrical in nature. Also, the security level is quite high. Only the private key person will have access; thus, the business becomes strictly between the sender and receiver.
These are the basic encryption types. With the upgradation of technologies, these have evolved. For example, the number of approved recipients can be increased by choosing encryption services like two fish, three fish, or blowfish. These allow keeping the privacy of data dissemination between a different number of recipients.
Online encryption types serve the need of people having different security level requirements. In addition to choosing the correct encryption, it is important not to fall prey to phishing emails or hackers’ attempts.
It is also advisable not to do business with companies that don’t disclose the encryption types they use. Keeping yourself updated about the newer encryption methods can also help derive their best benefits.
