   Solaris 2.6 and above, Linux, Win32, IBM OS/390
   Dependency: sfile_api.h, lib_sfile_XXX.a
   
   purpose:  explain the usage of the following functions:
   
   int PBE_EncryptFile(char* passwd,const char* in,const char* out);

   int PBE_DecryptFile(char* passwd,const char* in,const char* out);
