hi!
passwords of our internet users are stored in BAPIUSW01-PASSWORD as a password hash. The hash is calculated by the system-call XXPASSNET.
After we changed the password ruleset (kernel parameters login/min_password_digits and so on), hashes generated previously are no valid passwords anymore. The call returns an empty hexpass. In other words: no user can login anymore.
Is there a way to calculate a hash from a given string (=password) in the same way as XXPASSNET does? I already tried FM MD5_CALCULATE_HASH_FOR_CHAR or CALCULATE_HASH_FOR_CHAR, but they do not return the same result. Looks like XXNETPASS does not use MD5 or SHA1 but something else?
We authenticate using BAPI_PAR_EMPLOYEE_CHECKPASSWOR, which calls FM WWW_USER_AUTHORITY - inside, there is XXNETPASS called.
Thanks for all information 
Roland
