Talk:Data Encryption Standard

From Rosetta Code

REXX decryption[edit]

Has anyone an idea how to implement this:
"Decryption is simply the inverse of encryption, follwing the same steps as above, but reversing the order in which the subkeys are applied."

It works. Above failure was due to an error in my test. --Walter Pachl 11:05, 23 July 2017 (UTC)
