ASC X9 has released a new standard, X9.24-3, that allows the use of the AES DUKPT algorithm to enhance security in retail financial transactions.

Public-key algorithms are important too. They help get around the fundamental drawback of symmetric-key encryption, which is that you need a secure way to share symmetric keys in the first place.

The file data is then encrypted with a symmetric algorithm called as DESX. Encrypting File System (EFS) The key used for these kinds of symmetric encryption is called as File Encryption Key (or FEK).

As quantum computing threats loom, Microsoft updates its core crypto library Two algorithms added so far, two more planned in the coming months.

In contrast to symmetric-key algorithms, key encapsulation mechanisms in use today are easily broken by quantum computers.
