- (bal) [auth-passwd.c openbsd-compat/Makefile.in openbsd-compat/xcrypt.c
openbsd-compat/xcrypt.h] Split off encryption into xcrypt() interface, and isolate shadow password functions. Tested in Solaris, but should not break other platforms too badly (except maybe HP =). Also brings auth-passwd.c into full sync with OpenBSD tree.
