According to the latest encryption standards, 256 bit SSL encryption is considered the latest and safest encryption strength standard. However, when talking about 256-bit encryption, generally, users don’t know what it’s and what security it provides to websites. Therefore, let’s dig into the detail and know what you should know about 256-bit encryption.
Put simply, 256-bit encryption is one of the techniques that uses 256 bit keys for encrypting and decrypting the data transmission between the server and the client. Likewise, today’s most modern algorithms and protocols, along with AES and SSL, uses 256-bit encryption to generate secure pair keys of private and public security keys.
Furthermore, encryption is one of the processes that takes plaintext data, and with the help of an algorithm, it scrambles that data into an unreadable format which is called ciphertext. Likewise, it uses encryption keys that come in different sizes. So, if we look at 256 bit encryption strength, what it means is both the algorithm’s key and length used for encrypting the data are resistant to attacks. For instance, the larger the key size of the encryption, the harder it’s to crack or use attacks such as brute force.
Henceforth, whenever you find 256 bit SSL encryption within an SSL certificate description, it means it needs 2256 different combinations. Likewise, it also means it has around 115,792,089,237,316,195,423,570,985,008,687,907,853,269,984,665,640,564,039,457,584,007,913,129,639,936 combinations, which can take anywhere 3.31 x 1056 years to be cracked.
A secure 256 bit encryption standard is used for securing your online communication between the server and the client. It encrypts the information or data using a 256 bit long key before transmitting over the internet. Likewise, modern encryption protocols such as AES and even cheap SSL certificate uses 256 bit encryption for building a secure communication tunnel.
256 bit encryption is one of the common industry standards that’s used in many different ways. And some of the most commonly seen usages of 256-bit encryption are:
Put simply, 256 bits show the length of the encryption key. And the data transferred between the client and the server is encrypted through 256 bit encryption keys.
Nonetheless, let’s go through the below steps and understand the working of 256 bit SSL encryption:
The 256-bit encryption standard is among the safest security technology of the modern technology era that uses a 256-bit long key for encrypting and decrypting the data transmitted between the client and the server. Security protocols such as DV SSL certificates and AES uses for generating the public and private key pair as a part of PKI (Public Key Infrastructure).
Likewise, all types of SSL certificates provide the same encryption security level regardless of cost, brand, or validation level you choose to go with. And when it comes to encryption, a standard SSL certificate of $10 will provide the same encryption security which is found in the SSL certificate of $100 per year.
The strength of encryption that you get through an SSL protocol entirely depends upon how good the browser and server are configured. For instance, 256-bit encryption may provide you only 128 bits level security in some cases. So, if that’s the case, your server and browser aren’t configured with the latest features that help handle 256-bit encryption.
Therefore, it’s also recommended to make sure the browser and client are configured with all the latest security features so both are compatible enough to handle 256-bit encryption.
The 256 bit encryption strength you get along with an SSL certificate depends upon the capabilities of the browser and server and how well configured they’re. For instance, 256-bit encryption may provide security of only 128 bits if the browser isn’t updated with the latest version. And on the other hand, if the browser is equipped with all the latest configurations, it’ll successfully handle 256-bit encryption. Furthermore, with SSL, 256-bit encryption is pretty strong. And, by the time an attacker using the latest computer tries cracking 256-bit encryption, it’ll get discarded, and, likely, your SSL certificate will also get replaced with the newer one.
