A 256-bit encryption key means there’s 2256 possible combinations compared to 128-bit key which has 2128 possible combination a hacker would have try to break the encryption. In simple terms, 256-bit key takes 14 rounds of AES compare to 10 AES rounds of 128-bit key for each data block.

When you are searching for SSL Certificate, you will find 128-bit encryption and 256-bit encryption certificates.

It is an encryption method that uses just one key to help in both encrypting(encoding) and decrypting(decoding) data.

Due to the increase in cyber-attacks and newly techniques, higher encryption is needed so 256-bit encryption should be at least there to secure data.
