Advanced Encryption Standard or AES under the keys of standard size like 128, 192 and 256 bits denotes while encryption of electronic data is established. As 256 bit version is slower compared to 128 bit version, 256 bit version is considered as the safest key. Therefore 256-bit becomes the major differentiating factor among the two types of SSL certificates.

Bit

A bit is considered as the smallest unit to represent data in a computer.

Comparison between 128 bit and 256 bit SSL Certificate

The differentiating feature among the two encryptions relies on the negotiated cipher suit. It controls the particular connection. They are described under transport layer security or TLS. Let us take an example:

During a random connection into a network, security protocols are used by the browser for determining the ciphers suit supported by the server and the network. Cipher support depends on browser and server configurations.  The connection has not any link with the certificate or installed server.

Therefore with a primary connection hello message is sent by the client or browser to the server with a collection of concerned cipher suites. Strongest or most ideal cipher suite is picked by the server in return to offer support and response consequently. It is among 40, 56, 128 or 256 bit. The cipher can make an equal session key for encrypting or decrypting information.

The data is encrypted between the server and itself therefore the importance of cipher strength for 128 or 256 bit is denoted here. A private key is used for an identical pair of 1024 and 2048 bit certificates. Out of the pair, the data is encrypted by the one that are linked to public key and the certificate. Other can decrypt the data that are linked to the stored private key in the server.
