Encryption is the mathematical shell that protects the data stream. There are different levels of encryption that vendors refer to in their promotional materials such as 128 or 256-bit AES, which reflects the algorithm used to protect the data and how hard it is for an attacker to break in (128 or 256-bit).
The answer is that it is never secure enough (even though I suspect that using 256 bit vs 128 bit keys is a marketing strategy to make the client feel more secure). And don't forget the rise of quantum computing, which significantly lowers the amount of time needed for a brute-force attack. question of 128-bit versus 256-bit encryption is even a consideration. As a final note, and segue to the encryption engine discussion, the following observation is made. Seagate Secure™ hard drives have been designed with authentication key size of 256-bits.

There are different levels of encryption that vendors refer to in their promotional materials such as 128 or 256-bit AES, which reflects the algorithm used to protect the data and how hard it is for an attacker to break in (128 or 256-bit). 256-bit encryption is fairly standard in 2019, but every mention of 256-bit encryption doesn't refer to the same thing. Sometimes 256-bits of encryption only rises to a security level of 128 bits. Sometimes key size and security level are intrinsically linked while other times one is just used to approximate the other. 10 rounds for 128-bit keys. 12 rounds for 192-bit keys. 14 rounds for 256-bit keys. Each round consists of several processing steps, including one that depends on the encryption key itself. A set of reverse rounds are applied to transform ciphertext back into the original plaintext using the same encryption key. The BitLocker encryption algorithm is used when BitLocker is first enabled, and sets the strength to which full volume encryption should occur. Available encryption algorithms are: AES-CBC 128-bit, AES-CBC 256-bit, XTS-AES 128-bit, or XTS-AES 256-bit encryption. The default value is XTS-AES 128-bit encryption. Surely 256 is better than 128, and 2048 is even better yet. What does it all mean, and how much do you need? Encryption on computers uses the same principle as encryption of messages over the ages.

Still, within the AES encryption algorithm, it's better to go with the 256-bit key given that it is substantially more difficult to crack. However, once again, remember that your key length is not a true indicator of your actual encryption strength. 256-bit SSL may not always facilitate 256-bit encryption in practice.

As expected, the AES-192 and AES-256 bit keys have even more combinations they could be compared to AES-128. AES-256 vs AES-128. Naturally, a question will arise of which type of AES key should be used to encrypt video assets. This often translates into the question of which one offers superior encryption. The same is true about the encryption: no technology exists now that would break either 128-bit or 256-bit encryption. It would take the power of 15 Hoover dams for one year to just flip all of the 128 bits , not including the actual verification of each such key.
