128-bit encryption is a technique used to encrypt and/or decrypt data or files by using a 128-bit key to achieve that. It is considered to be one of the most secure and most popular online security methods. Interesting fact, 128-bit encryption is considered to be logically unbreakable, so you could say that 128-bit security is top notch!

Graphics processing unit (GPU) chips commonly move data across a 128-bit bus. 128 bits is a common key size for symmetric ciphers and a common block size for block ciphers in cryptography. 128-bit processors could be used for addressing directly up to 2 128 128 Bit SSL Encryption: What You Need to Know | Comodo SSL Key Length Matters — But That’s Not All. As you can see in the above table, it’s harder to crack keys of higher lengths. However, don’t automatically assume that because you’re using 128-bit key that it means your encryption strength is 128 bits. That’s because, right now, you could be using 40-bit encryption with 128-bit … What’s the deal with encryption strength —is 128 bit May 06, 2016

Ford 128-bit: Test Key: HU101: This 128-bit key is also backwards compatible with all other keys that use the Ford 40-bit and 80-bit chip and the HU101 high security keyway EXCEPT for the Ford Focus 2018.

These new types support 128-bit block encryption and key sizes of 128 or 256 bits. Using the "simplified profile" of [KCRYPTO], we can define a pair of encryption and checksum schemes. AES is used with ciphertext stealing to avoid message expansion, and SHA-1 [SHA1] is the associated checksum function.
