I’d been asked a few times recently for the code that generates the ICHDEX01 RACF masking exit. If you recall, this was the pre-DES (and long pre-KDFAES) algorithm that RACF used to store its passwords. (If you want more detail about this as the other algorithms, see my presentation from SHARE 2016) The algorithm, through… Continue reading RACF masking algorithm, unmasked
