John the ripper crack salted md59/18/2023 ![]() This table summarizes the details of all currently available password hash algorithms (as per Q4/2012): USR02. Give it a try, if you’re serious about the security of your passwords! Hash algorithms The password cracking tool John the Ripper (with the “Jumbo” patch) supports two of SAP’s common hash algorithms (CODVN B & F/G). SAP Note 1237762 gives a good overview of hash attacks and has some rather helpful tips on how to prevent them! one cannot/shouldn’t be able to retrieve the plain text password from the hash value… but that’s the point where the fun starts! □ Per definition, the result of a cryptographic hash function is/should be irreversible, i.e. The hash algorithm has changed several times over time – either due to weaknesses or as a result of the increase in computing performance (see “CODVN H” below). This history used to be limited to the last 5 entries per user before NW 7.0 meanwhile, the number of entries is customizable via the profile parameter login/password_history_size (see SAP Note 862989). Table USH02 and some others contain the password history (see SAP Note 1484692). ![]() The passwords of all users are stored in table USR02 as one (or more) cryptographic hash value(s). In this article, I’ll summarize, what I found out about SAP’s password storage mechanism (for SU01 users, not the SecStore).
