DATA encryption

[Vara Prasad]

Hi All,

I am having a problem to be solved Data text encryption and decryption.
I got an answer from the link
http://listserv.uga.edu/cgi-bin/wa?A2=ind0412&L=spssx-l&P=16411
as this shows how to encrypt the numeric.

But is there any method to do the same for Character aswell.
Like for example:
my text is "SPSSX-L" I want to encrypt this to "JSJJT-N".

Please help me on this.

Thanks.

Perhaps this won't work for you or you do not have 21 but if you look at the save command, you'll see an option for encryption.

If you don't like that, you could do the reverse or a variation of your example posting. The key is this code element

loop #POS = 1 to 10.
- compute substr(ENCRYP,#POS,1) = string((number(substr(string(MYNUM,f10),#POS),pib1)+99),pib1).
end loop.

Character by character you subtract (or add) a constant number to the integer binary value of the character.

In Statistics V21 or later, you can encrypt a sav file by using File > Save As and checking the encryption box or via the
PASSPROTECT subcommand on SAVE.  You can also encrypt output (spv) files.

In Statistics 22 you can also encrypt syntax files.
