But the export dump file is compatible from 8i to 9i, from one platform to another one, so why could we not suppose that the hash algorithm is independant from the version, the dbid, the database creation time, .... If it was'nt, I suppose there will be some notice from Oracle on Metalink as the compatibility of the export file will not be fully assured (the password would be all be lost).
