XUCODEVERS - Code Version of Password Hash Algorithm (Old Systems)
BAL Application Log Documentation Fill RESBD Structure from EBP Component StructureThis documentation is copyright by SAP AG.
Definition
The password hash algorithm and the selection of the fields to be filled are controlled using the code version:
The password hash value is in field USR02-BCODE (for code versions A and B) and in field USR02-PASSCODE (for code version C).
For code version C, the field USR02-BCODE is also filled with the hash (as with code version B), to be able to export this field contents to older systems(=> Central User Administration); the content of field USR02-BCODE is therfore identical for code versions B and C. The password history (fields USR02-OCOD1, USR02-OCOD2, ..., USR02-OCOD5, and USH02-BCODE) records the old password hash values for code version C as compressed values (mapping from 160 Bit to 64 Bit).
In future versions (as of code version D), only field USR02-PASSCODE will be filled; the field USR02-BCODE cannot then be evaluated any longer.
