Data Encryption Standard

And you're simply going to say, hey, if I need the same functionality, I need to replace it with something that does have it.

In a lot of cases, the vendor will have an upgrade for you, but it's important that you understand you need to communicate to your vendor and go, hey, what are you doing for post quantum? And let me say, I've been involved in hundreds of cryptographic migrations going from SHA-1 to SHA-2 and DES to AES.

I've probably done more cryptographic migrations than anybody I know.

I've done hundreds and hundreds over my career.

Symmetric, 23 braids.

2FISH3DES, Blowfish, RC5, AES, IDEA, DES, Skipjack, Asymmetric, Derrick-Q, Diffie-Hellman, Elgamal, RSA, ECC, Knapsack, Quantum.

The king of symmetric encryption is AES.

The Advanced Encryption Standard.

and it comes in 128, 192, and 256-bit strengths.

If you see a question asking for the best encryption for a hard drive, the answer is almost always AES.

You might also see 3DES or triple DES.

This is the old standard.

And I'll, I'll share just a, a very quick story.

In the nineties, there was the data encryption standard, was a, um, standardized algorithm for data encryption.

We went from DES to triple DES.

They said, "Well, we'll do it three times.

That's gotta be more secure." It was based on a substitution permutation network.

We, we don't know.

Should we trust it? And there was some concern about that.

It was revealed ten years later that the designers of the triple DES algorithm, they had uncovered a method of decryption called differential cryptanalysis.
