Are you sure both files are truly identical (e.g. corrupted when
copied) ? like have you run md5sum or sha1sum on both computers ?
Next what happens if you change SHA256 for other hash algorithms, like
SHA1, MD5, SHA384, SHA512... do you get the same results ? or something
different ?
If this is similar for all but SHA256 then please open a bug report on
bugzilla.novell.com
Thanks
