encrypted SPSS .sav files

[Ben Pfaff]

I see that recent SPSS supports password-based encryption of .sav
files.  If anyone is interested in having support for reading or
writing these files, then a good place to start would be to take a
small .sav and then save three or so versions of it, two of them with
the same password (to see whether the file content changes even if the
password does not) and a third with a different password, and then
send all the files, and the passwords, to the list.
